What is the temperature of a gas burner flame?

December 17, 2015

Gas burners are an indispensable assistant in the household, workshops and production shops, on a picnic and on hikes. Ease and ease of use have long given the primacy to gas appliances over other types. When choosing a burner, you should take into account the scope of application, the required power, as well as the maximum flame temperature. The last factor is especially important when performing more delicate types of work. Therefore, it is necessary to know the basic parameters directly related to the temperature distribution of the gas burner flame.

What determines the temperature of a gas burner flame?

A gas burner in a can and the flame temperature in it directly depends on the composition of the gas fuel, the ambient combustion conditions and the power of the equipment used. In this case, a direct relationship is observed between the calorific value of the gas and the temperature of the flame torch - an increase in the first indicator leads to an increase in the second.

When the process of mixing the fuel used with air occurs, the gas is completely consumed, which in turn increases the burning rate and increases the flame temperature. This indicator can be improved through additional use of air blast. For example, without the use of blowing, the maximum temperature regime is 1500 °C, but when using it, results up to 2200 °C are possible.

The temperature is also affected by the flame pattern. It is not homogeneous and is divided into three zones:

  • internal - is the shortest and has the lowest temperature indicators. It is in it that the gas mixture is heated, but without combustion;
  • The average reduction zone is the so-called light fire zone, in which the highest temperature is reached. Combustion already occurs here, but not at full power, due to the lack of oxygen and the presence of carbonaceous gas decomposition products;
  • bordering - characterized by the lightest flame, is oxidizing. The temperature of this zone is also high and due to excess air, complete combustion of the gas occurs.

Main selection criteria

Experienced buyers advise when choosing a gas burner to consider the following parameters:

  • – The main thing is to decide on the purpose of purchasing the burner. To perform construction work and simple household needs, different models are needed.
  • – For construction work, it is best to choose a gun-shaped torch. It will be convenient to hold it in one hand, while the other can be used to support the material with which you are working.
  • – Manufacturers offer compact models for hiking and trips to the country. They can easily fit in a backpack or car glove compartment.
  • – Models with a low melting point are suitable for soldering pipes.
  • – One of the main parameters is gas consumption. This will allow you to calculate how long one replacement cylinder will last.

Gas combustion temperature under different modes in a gas stove

Let's find out what gas is used in household appliances - stoves and boilers for heating systems, as well as its properties.

Gas is the most common energy resource used for cooking, heating water and heating buildings. The amount of heat released during its combustion is considered an important technical parameter of this fuel, and also determines the ease of use of one or another gas equipment and fuel consumption for various purposes.

Types of portable burners

Gas burners are devices that differ in design and purpose, but they are united by a common feature - they operate using gas.

Portable devices designed to operate from a small tube filled with propane-butane or other gas should not be confused with ovens or powerful welding units that operate from natural gas or a large cylinder.

We offer a brief overview of the main design elements of an inexpensive gas cartridge burner, which serves as an excellent example of a home device. It may be useful for repairs in the country or for a barbecue.

Using a compact device, you can quickly light a barbecue, heat bolts or nuts in the cold, melt plastic parts, and process heat shrinks. The flame temperature (up to +1300°C) is enough for soldering metal pipes.

This is an example of a burner type that is popular among users, but the range of devices is much wider. Let's look at the most popular types.

Difference by area of ​​use

An open flame may be required at home, on vacation, and during installation work. One of the areas of application is tourism. When camping, use a simple device to light a fire and heat up canned food.


Devices for heating food have a special design - instead of a muzzle-nozzle, there is a long thin gas supply hose to an external burner with a stand

Burners with a directional torch of a “pistol” type are often used in installation work when soldering copper pipes and for bending plastic elements.


The flame, heated to the required temperature, is directed to the mating area of ​​the copper parts, resulting in a strong permanent connection between pipe and pipe or fitting.

High-temperature high-power lamps can also process steel parts, but this requires hard solder and a slightly modified soldering technique.

Gas portable burners are also used for the following work:

  • processing of wooden parts;
  • lighting a barbecue or a fire in the country without the use of chemicals;
  • calcination and cutting of metal blanks;
  • singeing animal carcasses during butchering;
  • thawing frozen pipelines.

This useful device is always at hand for craftsmen who love to improve their homes and improve their garden plots on their own. The burner can be useful in a car repair shop, during the construction of a greenhouse or other structures.

Division according to the method of attaching the can

The fuel cartridge is a consumable item. As soon as the fuel runs out, it is disconnected from the burner, and a new cartridge is installed in its place.

There are several ways to attach a cartridge to a device:

  • threaded - fixed with a thread, in other words - screwed on;
  • collet - put on and slightly rotated to one side;
  • valve - secured with a retainer;
  • pierced - connected with light pressure.

Threaded models are more common than others. They form a strong connection between two elements that can be separated at any time. Punctureable ones, on the contrary, cannot be turned off until the gas in the can runs out.


Devices with collet fixation are quickly installed. To attach them to the cylinder, you just need to put them on and turn them 25-30 degrees to the side

The weakness of collet devices is the rapid loosening of the clamp, resulting in loss of gas.

Valve burners, which are usually designed for heating food, are considered more reliable.

Differences in gas burners by fuel type

Manufacturers use various fuels to fill consumable cartridges. The choice of liquefied gas is based on the purpose of the burners, the required flame temperature, and power. To improve the characteristics of the composition, several different types of fuel are sometimes mixed.

The following combinations of substances are used most often:

  • a mixture of propane and butane (70:30) - mainly for summer use, but with a heating device it is also used in winter;
  • a combination of propane, butane and isobutane in various proportions;
  • a mixture of MAPP - methyl acetylene-propadiene-propane, most often used for welding at temperatures of 1600-2500 ° C.

But there are cans filled with one gas, for example, butane.


An example of inexpensive gas cartridges is “Pathfinder”. Price – 90 rubles. Filling – universal gas fuel, suitable for portable burners, cutters, stoves, heaters

The choice of fuel is important when work is to be done in harsh conditions - in the cold or at high altitudes. And in the summer, any universal gas is suitable for lighting a barbecue or fire.

How to choose a gas burner for a spray can

This type of equipment is highly autonomous, which expands its scope of application. The simple design reduces the price and reduces scheduled maintenance to a minimum. The use of tight push-in connections ensures safety. Manufacturers offer models with injectors and check valves, working in conjunction with various types of tanks. Which nozzle to choose? It is not difficult to understand this issue. The buyer needs to understand the main purpose, pay attention to the presence of a flame regulator, piezo ignition and evaluate gas consumption. This will help you buy a tool that will last for several years.

Purpose

To light a fire in the country or during a camping trip, you can use the simplest nozzle, which can easily cope with the task or replace the stove if necessary to boil water. Such models have a flame temperature of 500-700 degrees and have a low price. Losing equipment during your next trip to nature will not be a serious loss. Tourists are advised to evaluate the size of the attachments, which should not take up much space in a backpack or car trunk.

For soldering, heating plastic and glass, you can use models with a torch temperature of 1200-1300 degrees. These are the most universal attachments, actively used in construction and in the home workshop. To solve specialized problems, for example, bending reinforcement, you will need powerful models with a flame temperature of 2200-2300 degrees. When choosing a tool, the conditions in which the user uses the burner are also taken into account. When used in conditions of limited space, nozzles with small sizes have an advantage.

Flame regulator

When choosing a universal model that is designed to solve different problems, nozzles with a flame regulator have an advantage. This device allows you to regulate the gas pressure and measure the power of the fire flow and its temperature. Using the regulator, the optimal mode is selected for soldering with copper or tin, heating a rusty part or old paintwork. The wider the adjustment range, the better for universal equipment.

The regulator should have a convenient location and allow you to change the power of the nozzle while working with the tool. Manufacturers who care about their customers put a power scale and direction of adjustment on the valve. This simplifies setting up the burner when performing critical tasks.

Piezo ignition

The piezo ignition system allows you to do without the use of matches when igniting the flame. This increases the safety of use: when igniting, accidental burns can be avoided. Piezo ignition is triggered in the wind and during rain, ensuring the operation of the device in all weather conditions. The spark instantly ignites the fuel, saving the user’s personal time. Piezo ignition must have a reliable and durable switching system: if the button breaks or sticks, then it will not be possible to use the piezo element for ignition. The system does not greatly increase the price of the tool, so it is recommended to choose models with piezo ignition.

Gas consumption

The nozzles are used with cylinders that have a limited fuel supply. The main part of the burners works in tandem with tanks that hold 220 grams of butane-propane mixture. The lower the fuel consumption, the longer the operating time. Consumption depends on the design features of the equipment. The optimal gas consumption is 75-80 grams per hour. This allows you to work for 2-2.5 hours.

Injection type nozzles have a higher flame temperature and power. High-temperature burners consume up to 120-140 grams of fuel per hour. To increase operating time, it is recommended to use 600 ml cylinders with such nozzles, which can hold more than 300 grams of the gas mixture.

The difference between propane and methane

Among the distinctive features of propane it is worth noting:

  • higher combustion efficiency, making it much more efficient than methane during welding;
  • high inertness of the gas, which allows it to more actively enter into various chemical reactions;
  • propane is safer than methane and has a narcotic effect;
  • When transporting propane, you do not need to use any special equipment; ordinary steel cylinders are sufficient.

In addition, propane is cheaper and easier to refill.

Tips for choosing the best burner

People buy compact hand burners with pleasure, as they have many advantages over liquid fuel, more “serious” devices. They light quickly, hardly get dirty, and require a minimum of care.


Using a manual model is easy: the flame power can be adjusted and the torch can be directed at any angle, which is important when working in cramped conditions

Criterion #1 – scope of use of the device

First of all, you should determine exactly what the gas appliance will be used for, since burners for soldering and for heating food are radically different in both design and parameters.


Tourist devices have the shape of a stand and resemble a household gas stove, on which it is convenient to place dishes with heated food

Construction tools often resemble a gun in shape. When working, it is convenient to hold them with one hand, and with the other at this time you can support the part or bring solder.

Criterion #2 – technical characteristics of the model

Characteristics such as weight and size are important if the burner has to be taken on hikes or often used at home. A heavy tool causes rapid fatigue, while a light one is much more comfortable to work with.

We pay attention to such characteristics as:

  • flame temperature – from 480 to 2500°C;
  • heating temperature – from 550 to 2500°C;
  • power – 0.5-3 kW;
  • the ability to connect cans with different fuels;
  • method of connecting the cartridge to the burner;
  • flame type, torch shape;
  • fuel consumption – from 60 to 1000 g/h;
  • weight – from 50 grams to 1.7 kg.

If you are purchasing a torch specifically for soldering copper pipes, then a low-temperature model will do.

To cut or weld steel parts, you will need a more powerful machine, usually called a torch or welding torch.

Overview of additional useful options:

It is not surprising that portable devices are popular, but when purchasing, you need to take into account all the nuances, including technical characteristics, design features, efficiency, and ease of use.

Technical parameters of blue fuel

  • Flame temperature at different modes
  • Dependence of temperature on fuel type
  • Determination of flame temperature

Flame temperature at different modes

The gas mixture begins to ignite at 640–700 degrees, depending on the quality and composition of the gas, and the combustion process begins only at 800–900 degrees. This temperature is quite enough for cooking and heating water in a gas water heater. Gas boilers intended for home heating also operate in the same temperature range.

However, the temperature of the flame in different parts of it is not the same. The heterogeneity of the flame can be clearly seen upon closer examination.

The highest temperature is observed in the upper part of the flame, where it reaches a value of 1400 degrees. The maximum combustion temperature of the gas is 2043 degrees. However, such figures can only be obtained with powerful industrial equipment. On a kitchen stove, the flame is limited to a maximum of 1500 degrees.

In addition to the quality of the gas mixture, the temperature of the burner depends on the intensity of the fire, which is regulated by rotary knobs located on the gas stove or regulators on the boiler. Turning the tap at a small angle increases or decreases the fuel supply to the burner, thereby increasing or decreasing the heat transfer of the flame.

How to choose a gas burner

Tourist burners are the most popular; many buyers who are faced with a choice for the first time sometimes prefer expensive Polish models, which in this situation does not justify itself.

Inexpensive, simple, non-supercharged torch designs are quite suitable for hiking. The cheapest Chinese models can light a fire and heat up food, which you won’t mind losing or damaging in camping conditions.

For use at home and when performing simple repairs, they purchase amateur series instruments, which are more expensive compared to tourist options, but they do not have problems such as melting of the plastic coating of the mouthpiece and disruption of the piezo ignition system.

In order to make a choice of model, the user needs to pay attention to the following characteristics of the device:

  1. The presence of a control valve, especially when performing a large volume of soldering work.
  2. To perform fine soldering or welding, pay attention to the balancing and ergonomics of the design, since frequent switching on/off of the torch must be done with one hand.
  3. Power is selected according to the thickness and materials of the processed products. Burners with a power of up to 0.7 kW are capable of soldering copper wires or burning paint; for soldering steel products up to 3 mm, a power of about 1.5 kW will be required, and powerful devices from 2.0 to 3 kW are used to heat fittings up to 12 mm.
  4. You also need to know how long the gas cylinder lasts.

Highest flame temperature

This indicator determines the cutting speed of the material and is determined by the properties of the gas-air mixture and the type of fuel. A high value is guaranteed by acetylene; the substance rapidly heats the metal to melt . At the tip of the fire the temperature reaches about 3000 degrees. The farther from this point, the smaller the number.

Welder of the highest category of Progress LLC Degtyarenko V.O: “The increased temperature of the torch also has negative consequences: melting of some of the edges of the workpiece. For this reason, acetylene does not produce the same cutting quality as kerosene or gasoline vapors.”

Rules for safe use

Gas burners on a canister operate with flammable mixtures and open fire, which is always associated with the risk of fire and thermal burns. In connection with this, even when using the simplest such device, it is necessary to strictly observe fire safety rules.

It is recommended to start using such a torch by studying the manufacturer’s instructions and then strictly follow them when performing soldering work.

When using the burner, do not allow the can to overheat due to its close location to an external source: fireplace, boiler, in the sun or near a fire. Heating the housing can lead to an explosion, which will damage the walls and can cause injury to others with sharp edges.

Professional reusable gas burners require special care, which is also specified in the manufacturer’s instructions. For example, in order to maintain the functionality of the burner, the power and length of the torch, the burner is packaged in a catalytic heating pad.

Adjustment

The cleanliness of the cut depends on the correct flame setting . Oxygen treatment is carried out with a slightly oxidized or normal torch. The carefully adjusted flame of cutters with concentric nozzles is surrounded by a cutting stream of oxygen. The core of the torch in each section should be symmetrical and not differ in brightness.

Cutting with a torch with the mouthpiece moved cannot be carried out, as this will lead to heating of the edge, which will negatively affect the quality of the cut. The use of self-centering mouthpieces increases the ease of use of such equipment, because the device makes the flame symmetrical.

Sometimes the movement of the gas mixture is hampered due to clogging of the channel, which divides the torch into streams and leads to loss of stability. Such a product not only reduces the quality of processing, but also reduces productivity. Flame adjustment is based on creating a symmetrical flame of the required power in relation to the oxygen cutting jet.

Do-it-yourself refilling of mini-burner cans

Before starting the refilling process, make sure that the cylinder does not have any remaining gas mixture. It is turned over so that the valve is at the bottom and shaken.

Refilling process for mini burner:

  1. Take ordinary scales and weigh the empty cylinder so that after the process is completed you can determine the exact amount of fuel mixture filled.
  2. Connect the container to be filled with a propane cylinder using an adapter.
  3. Close the valve on the adapter.
  4. Open the valve on the can.
  5. Gradually open the valve on the adapter, at this moment gas enters, squeezing the air out of the hose.
  6. Monitor the filling process and, after completion, disassemble the circuit in the reverse order.
  7. Disconnect the tourist cylinder.
  8. Using the shaking method, the presence of gas is determined; the liquid in the vessel should flutter, which indicates the presence of a mandatory free space, which experts call a gas cap.
  9. Check the valve for leaks with a soap solution. Verification by fire is strictly prohibited.

What to do if it doesn't burn well

Often users of a gas burner on a can encounter a situation where the gas burner does not burn well. To avoid clogging of the burner nozzle, experts advise filling such devices only with purified fuel mixture used for filling lighters.

A common reason for the mini-burner to stop functioning is the ring in the nozzle falling out, after which the spark does not hit the ring, but flies in different directions, in which case ignition does not occur.

If the ring is lost during operation, it must be replaced by making it from ordinary copper wire.

Tips for choosing

To make the right purchase and not regret it after some time of use, we suggest using a few tips from experienced buyers and experts:

  • The first step is to decide on the purpose of using the burner. It can be used for soldering pipes or cooking food on the go.
  • Construction models are made in the shape of a pistol, since it is convenient to hold them with one hand and hold the material needed for work with the other.
  • Pay attention to the dimensions of the structure if you take the burner with you on hikes.
  • It is better to take a model with a maximum melting point.
  • If you will be working with pipe soldering, then a model with a low operating temperature is sufficient.
  • In order to cut and weld steel products, you should purchase a device with high power, which is sometimes called a welding lamp.
  • Look at the gas consumption per minute, since this parameter will determine how long one cylinder will last and when you will have to install a second one.

Operating principle and features

The user receives an even torch, the power of which is controlled by a special valve.
Due to this, the temperature at which it heats up changes depending on the thickness of the material and the tasks being pursued. The device is more cost-effective for welding and cutting than massive, expensive equipment.

The range of uses is so wide that the product is even used for disinfecting wooden hives, treating animal cages, roofing, and so on..

The burner is ignited with matches, a lighter or an open fire source. This option is cheaper than models with installed piezo ignition. This element leads to combustion after pressing the button, which provokes the appearance of a spark, which ignites the gas jet.

According to the principle of operation, the piezoelectric element resembles a familiar lighter.
