Reduce NOx emissions from biomass boilers by implementing the following measures:
Combustion Control Technology: Utilizes advanced combustion control techniques, such as low nitrogen combustion technology. By optimizing the combustion process, controlling the combustion temperature and oxygen concentration, and reducing the formation of nitrogen oxides. Methods like staged combustion and optimized combustion chamber design can be employed to lower combustion temperatures and extend combustion times, thereby decreasing nitrogen oxide formation.
SNCR Technology: Selective Non-Catalytic Reduction (SNCR) technology involves injecting reductants, such as urea solution, into the combustion process to react with nitrogen oxides, converting them into nitrogen and water. This technique reduces the formation and emissions of nitrogen oxides during combustion.
SCR Technology: Selective Catalytic Reduction (SCR) technology is a nitrogen oxide control technique. By injecting urea solution into flue gas and utilizing a catalyst, nitrogen oxides are converted into nitrogen and water. SCR technology achieves nitrogen oxide removal at lower temperatures, making it suitable for large biomass boilers.
Flue Gas Recirculation (FGR): FGR technology recycles a portion of flue gas back into the boiler combustion chamber, reducing combustion temperature and oxygen concentration, thereby decreasing nitrogen oxide formation. This technique can control nitrogen oxide emissions by adjusting the recirculation ratio.
Fuel Selection and Pretreatment: Choosing low nitrogen fuels, such as low nitrogen biomass fuels, can reduce the formation of nitrogen oxides. Additionally, for biomass fuels with high nitrogen content, pretreatment measures such as drying and gasification can be taken to decrease the formation of nitrogen oxides during combustion.
Regular maintenance and cleaning: Regularly maintain and clean biomass boilers to ensure the cleanliness and proper operation of components like burners and heat exchangers. Cleaning the combustion chamber and heat exchangers reduces soot buildup, enhances heat transfer efficiency, and lowers nitrogen oxide emissions.
By implementing the aforementioned measures comprehensively, emissions of nitrogen oxides from biomass boilers can be effectively reduced, achieving both environmental protection and energy-saving goals. The specific measures to be chosen should be based on the characteristics of the boiler, its operating conditions, and emission requirements.

Advantages of biomass fuel:
Renewable Energy: Biomass fuel is a renewable energy source with a wide range of sources, including wood, straw, and waste materials. Compared to fossil fuels, the supply of biomass fuel is more sustainable.
Environmental Friendly & Low Carbon: The amount of carbon dioxide released during the combustion of biomass fuel is roughly equivalent to the amount absorbed during its growth, resulting in almost no net increase in carbon dioxide emissions, which has a positive effect on mitigating climate change.
Reduce Waste Disposal: Biomass fuel can utilize agricultural straw, wood waste, and other waste materials, thereby reducing waste disposal and emission issues.

The internal structure of an automatic biomass boiler typically includes the following main components:
Combustion Chamber: The combustion chamber is the area within a biomass boiler where combustion takes place. It typically consists of a burner, combustion chamber walls, top, and bottom. The combustion chamber provides the space and oxygen required for combustion, allowing biomass fuel to burn and generate heat.
Chimney System: The chimney system is designed to guide flue gases produced by combustion out of the combustion chamber. It includes flue pipes, chimneys, and flue gas purification equipment, etc. The design and layout of the chimney system can effectively enhance the efficiency of flue gas emissions and thermal energy utilization.
Heat Exchangers: Heat exchangers are a crucial component in biomass boilers, used to transfer the thermal energy from the flue gas produced by combustion to water or other working fluids. Common types of heat exchangers include water tube heat exchangers and flue tube heat exchangers. The design and material selection of heat exchangers are essential for improving
