Reducing nitrogen oxides (NOx) emissions from biomass boilers can be achieved through the following measures:
Combustion Control Technology: Utilizes advanced combustion control techniques, such as low nitrogen combustion technology. By optimizing the combustion process and controlling the combustion temperature and oxygen concentration, nitrogen oxide emissions are reduced. Methods like staged combustion and optimized combustion chamber design can be employed to lower combustion temperatures and extend combustion times, further decreasing nitrogen oxide formation.
SNCR Technology: Selective Non-Catalytic Reduction (SNCR) technology involves injecting a reductant, such as urea solution, into the combustion process to react with nitrogen oxides, converting them into nitrogen and water. This technique can reduce the formation and emission of nitrogen oxides during combustion.
SCR Technology: Selective Catalytic Reduction (SCR) technology is a nitrogen oxide control method. 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): The Flue Gas Recirculation (FGR) technology recycles a portion of flue gas back into the boiler combustion chamber, reducing combustion temperature and oxygen concentration, thereby minimizing the formation of nitrogen oxides. 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: Perform regular maintenance and cleaning on biomass boilers to ensure the cleanliness and proper operation of components like burners and heat exchangers. Cleaning the combustion chamber and heat exchangers can reduce the buildup of dirt, enhance heat transfer efficiency, and decrease nitrogen oxide emissions.
By implementing the aforementioned measures comprehensively, nitrogen oxide emissions from biomass boilers can be effectively reduced, achieving both environmental protection and energy-saving objectives. 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, making its supply more sustainable compared to fossil fuels.
Environmental and Low-Carbon: The amount of carbon dioxide emitted 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 impact on mitigating climate change.
Reduce Waste Management: Biomass fuel can utilize agricultural straw, wood waste, and other waste materials, thereby reducing waste management 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 the burner, combustion chamber walls, top, and bottom. The combustion chamber provides the space and oxygen needed for the biomass fuel to burn and generate heat energy.
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 Exchanger: A heat exchanger is a critical component in biomass boilers, designed to transfer thermal energy from the flue gas produced by combustion to water or other working fluids. Common types of heat exchangers include tube-type and flue-tube type. The design and material selection of the heat exchanger are essential for improving
