Gas burner device, starting and adjusting the flame, recommendations for disassembly and storage

Every owner of an apartment or private house, where gas equipment for the heating system is installed, faced problems related to its adjustment or interruptions in work, right? To ensure the correct operation of the heating system, you need to know the nuances of the operation of gas appliances and the peculiarities of their settings, and all this information is collected in this article.

This publication also contains comprehensive information on the types and design of a gas burner. In addition, you will find information on setting the flame in gas burners and the main reasons why your equipment is malfunctioning or not working at all.

Burner device and its varieties

All heating boilers differ in the type of fuel that is used in them. The most accessible, of course, is

gas. This type of fuel is the most common and from it the least amount of combustion waste. At the same time, the level of efficiency is quite high.

A standard gas burner is the main element in the heating system, which supplies and ignites fuel in a gas boiler. We will talk in detail about the device and principle of operation of the burner below.

How does a gas burner work and work?

The gas burner is designed to supply a combustible mixture together with air, then these components are mixed in the combustion chamber. The next process is to keep the fuel burning evenly.

The principle of operation is presumably divided into the following stages:

• preparation;
• compound;
• combustion.

So, first, all the necessary components of the combustible mixture go through a preparatory process. They gain a certain speed, temperature and the desired direction of movement of particles. Further, the fuel is combined with air and enters the fuel combustion chamber. After that, it ignites.

The main structural elements of a gas burner are considered in the diagram below.

With regard to possible burner breakdowns and safety use of gas equipment at the same time, the boiler manufacturers did not forget to take this point into account. So, in all modern boilers there are additional structural elements that ensure safer operation and automatic shutdown in case of burner breakdown or other emergency situations.

When some elements of the equipment fail, then in the event of a breakdown, the device turns off on its own.

There are models in which ignition occurs by supplying a spark from an electric piezoelectric element. But even in such boilers there are also constituent elements that are able to ensure the safety of the use of equipment in the event breakdown of a gas burner or for other malfunctions.

To avoid any problems during the ignition of the burner, it is important to carry out maintenance in a timely manner. Obligatory inspection and maintenance of the gas boiler must be carried out before the heating season, but at least once a year.

The main types of burners for a gas boiler

For maximum efficiency of the heating system in a private house, a burner is installed in a gas boiler. Such equipment facilitates the regulation of combustion processes in the system. As a result, the fuel burns evenly.

Burners are divided according to the principle of operation into:

• injection;
• turbocharged;
• combined.

Injection (injection) type of gas burners - an integral part of the gas boiler. It works in such a way that air enters the working area by injection. To evenly maintain the combustion process, the oxidizer enters the tank under a certain pressure and mixes with the gaseous fuel.

This type of appliance is designed exclusively for use with natural gas. For another type of gas, for example, liquefied, it is necessary to install additional elements.

The second type of burners (turbocharged) works in a different way. Here air enters the working area and mixes with combustible fuel using a fan. Thanks to the control system, it is possible to regulate the speed of rotation of the blades, thereby regulating the supply of the oxidizer. Such a device allows high-quality increase boiler efficiency.

Despite the noise that comes from the fan, such devices are quite effective, and unwanted sounds can be eliminated by installing additional noise canceling devices. They are more productive. But, as you know, turbines often fail if the operating rules are not followed.

But, there are also burners combined type. They are also designed for boilers and work not only on gas, but also on other types of fuel. For such heating systems, additional structural elements are not needed, since they were installed initially. These types of equipment are much more expensive.

Also burners are divided into industrial and household. There is practically no difference between their principle of operation.

But, despite the differences in the design of gas burners, they are all designed for high-quality fuel combustion.

Setting the gas burner flame

To properly adjust the burner of a gas boiler, first of all, you must follow the instructions for use of the gas appliance. Next, we will talk about how to properly start up and adjust the gas burner, and in what cases it is necessary to adjust the flame. But first things first.

Features of setting the boiler burner

It is recommended to tune the burner flame using a gas analyzer. It shows information about the amount of air, which mixes with the gas, namely the level of oxygen involved in the process and the amount of CO.

Typically, the CO should be no more than 50 ppm, and the oxygen concentration should be about 3 to 5%. If it is less, then it is most likely that the gas will not have time to burn, as a result of which, a lot of soot will accumulate, the level of CO₂ will be higher than the norm, and the efficiency of the equipment will decrease.

If the air is more than normal, then the temperature of the household burner of the gas boiler will be too high, and this can lead to tragic consequences, up to the explosion of equipment.

The flame in the gas burner should be blue. If you find that the color has an orange tint, then try to reduce the amount of gas. Reduce until the color turns blue (cyan). This color is a sign of optimal operation of the gas appliance. The main thing is not to reduce the fuel supply until the moment when the flame becomes almost colorless. In this case, it will go out very quickly.

Setting the starting gas supply is necessary only during ignition and does not affect the performance of the device. But if necessary, it is possible to adjust it. First you need to reduce the starting fuel supply. Decrease until the burner stops turning on. After that, you can turn the knob until the ignition is resumed. For more details on setting the flame of a household gas burner, see the video at the end of this article.

We also recommend that you familiarize yourself with the intricacies gas boiler regulation.

When is flame adjustment necessary?

An atmospheric-type gas burner that works without a built-in fan often fails, a turbocharged one is much less likely to break down. During prolonged use of the device, its components may break or stop working at full capacity.

For example, a gas-fired boiler may have a drop in efficiency, or a decrease in flame may be observed.

And this can happen for the following reasons:

• Higher burner capacity installed for equipment designed for lower burner capacity. In this case, there is not enough space for proper fuel combustion, the fuel burns unevenly, which leads to the fact that carbon deposits quickly accumulate on the parts of the equipment.
• A lot of carbon deposits in the chimney can have a bad effect on the draft of a gas boiler. Because of this, the subsequent withdrawal of combustion products is very weak, little air enters, and the flame turns yellow.
• The presence of burner defects is one of the reasons for the decrease in boiler efficiency, but in this case, adjusting the flame will not help not fix the problem.
• Pressure drops during gas supply can also contribute to the formation of soot and carbon deposits, and this will significantly reduce the productivity of the equipment.

All these reasons can affect the temperature of the flame in the gas burner, in which case repairs will be required.

Storage and Disassembly Recommendations

All gas appliances require careful handling and adherence rules for safe operation. Therefore, it is not recommended to unauthorizedly eliminate malfunctions or disassemble the burner and the gas boiler itself.

In order to avoid accidents, as well as to ensure the correct and efficient operation of the device, it is best to contact the gas company with which you have contract signed for THAT. Calling a specialist will be the most reasonable decision, because the cost of your life and the lives of the people around you is much higher than contacting a specialist.

As for the storage of household gas burners, everything is simple here. They must be stored in a dry and ventilated area to avoid corrosion of metal parts.

To store the boiler itself, you must make sure that there are no plugs at the outlets for connecting the heating pipes.

You also need to make sure that there is no water inside. If the water is not drained, the reservoir will rust and the boiler will be unusable.

Conclusions and useful video on the topic

We advise you to watch a video on setting the flame in a gas burner. This video describes the main problems of a gas burner when a flame adjustment is required.

Watch the following video clip, which details the main reasons why your gas burner is not working properly, or has stopped firing at all. The most common reason is the accumulation of large amounts of soot, which forms from incomplete combustion of gas:

Try to use your own equipment correctly if the start of the gas boiler burner occurs with some interruptions, it means that you urgently need to carry out diagnostics and find out the cause of the interruptions, otherwise the device can harm your property or life.

It is also worth remembering about the storage and transportation of gas burners. To do this, you need to study the operating rules, which are written in the documentation. Such documents should be included in the package when purchasing the equipment. In any case, when clarifying any malfunctions, urgently contact the gas service or reliable specialists who will help you solve the current situation.
