What is the Working Principle of a Burner?
The working principle of a burner can be briefly summarized as; the burner turns the fuel into a combustible gas and sprays it into a combustion chamber where it burns. This combustion generates heat and energy, which is used in heating systems.
As we mentioned in detail in our previous blog post titled "What is a burner?", burners are mechanisms that use fuels such as natural gas, biogas, fuel oil, diesel oil, solid fuels, LPG, LNG, CNG, etc., and produce heat and energy as a result of their combustion. Burners are systems that work thanks to the combustion process in combustion chambers. Burners work through air, fans powered by electric motors and liquid fuel pumps, and the working principle of the burners is designed according to the characteristics of the control system and the combustion chamber. In response to the question of how the burner works, heat is released due to the chemicals in the fuel coming into contact with air. In this context, burners are classified according to their features and fuel types.
In this article, we will briefly discuss the basics of boiler burners, the characteristics of burners, their purpose in the system, and different burner types.
The purpose of burners, which ensure the complete combustion of fuel by mixing it with air in the appropriate ratio, is to safely provide the formation of a flame by mixing liquid or gas fuel and air in normal proportions. The fuel's carbon, hydrogen, and sulfur elements react with oxygen. As a result, the combustion process takes place. The burner operating system can also be expressed as supporting the complete combustion of the fuel coming to the burner by mixing the fuel used in the boilers with the air to the optimum extent. The most crucial feature of burner systems is that the combustion air is distributed utilizing a fan.
In burner design, burner types are determined according to the combustion chamber's characteristics and the fuel used. Below, you can find definitions and explanations of the most common burner types:
In atmospheric burner systems, the gas used as fuel is mixed with the air absorbed by the burner as it expands in the device, and thus the combustion activity is realized. Heat traps in this type of burner, mainly alloy metal or ceramic rods, can reduce the flame temperature. Atmospheric burners use natural air for gas combustion, while blown burners use pressurized air with the help of a fan. Natural gas burners are divided into atmospheric and blowing burners.
Proportional burners are devices that control the heat generated during combustion by changing the combustion rate of the fuel. This ensures an ignition point that can be maintained at a specific temperature. Proportional burners use a control unit that adjusts the flow of air and gas to control the combustion rate of the fuel. This improves the combustion efficiency of the fuel and reduces emissions. Proportional burners are used in many applications, such as industrial heating systems, boilers, and furnaces.
A gas burner is a device that transports fuel gas into the combustion chamber and allows it to burn there. The working principle is that the gas is mixed with air during transportation to the combustion chamber and ignited with a spark or pilot flame. The heat energy generated from this combustion process can be used for different purposes depending on the design of the burner. For example, gas burners used in homes provide heating and hot water. In contrast, burners used in industrial plants provide heat for power generation or production processes.
Liquid fuel burners are used when the fuel is in liquid form. These burners generate heat by spraying the fuel and then burning it. The burners use a spray nozzle to spray the fuel, which is ignited by an ignition source. The flame created by the combustion of the fuel heats a heat exchanger inside the burner, which in turn gives off heat to the outside. Liquid fuel burners are widely used for heating and power generation in homes, industrial plants, and vehicles.
