Low-NOx burners and low-NOx burners refer to burners with low NOx emissions during the fuel combustion process. The use of low-NOx burners can reduce nitrogen oxide emissions during the combustion process.
The essential elements of boiler low-nitrogen burner technology: in order to solve the problem of how to effectively use low-quality exhaust gas and ensure the temperature of the flue gas in the denitration system to complete the flue gas denitration treatment, a flue gas heating device for the denitration system is provided.
The technical solution adopted for one of the key elements is: the flue gas heating device for the denitrification system, including the main pipe through which the fuel is introduced, the main pipe is connected to the combustion chamber and the denitrification flue in turn, and the main pipe is connected to the combustion chamber through a gas burner , It also includes an air supply device connected with the gas burner, the main pipe is provided with a pressure measuring device, a flow measuring device and an adjusting device, and the pipe between the combustion chamber and the denitration flue is provided with a temperature measuring device.
An independent combustion chamber is used to burn the fuel to produce high-temperature flue gas and then mixed with the low-temperature flue gas in the denitration flue to ensure the temperature required for flue gas denitration; an independent combustion chamber can better ensure ignition and combustion It is stable and has strong adaptability to heating fuel; according to the flue gas temperature measured by the temperature measuring device, the adjusting device can adjust the amount of fuel injected into the combustion chamber. Through the adjusting device, the combustion chamber can be controlled better. Control the flue gas volume and temperature of the combustion chamber.
The air supply device includes an air blower and an air supply pipe. The air blower is connected to the gas burner through the air supply pipe, and has a simple structure and low cost.
The pipes of the combustion chamber and the denitration flue are evenly arranged with a plurality of flue openings deep into the denitration flue to strengthen the mixing of the high-temperature flue gas discharged from the combustion chamber and the low-temperature flue gas in the denitration flue.
The above is an introduction to the implementation elements of low-nitrogen burner technology for Zhoukou professional boilers. If you want to know other content of low-nitrogen burners, please pay attention to Zhengzhou Bona Thermal Energy Equipment Co., Ltd.!
