[0002] Biomass combustion energy supply is a technology that uses biomass resources as fuel and converts the chemical energy in biomass into heat or electricity through the combustion process. Biomass resources can be regenerated every year and have a large output, making it a sustainable source of energy. Biomass fuels have low sulfur and nitrogen contents, and produce fewer pollutants such as sulfur oxides and nitrogen oxides during combustion. At the same time, the CO2 released by biomass during combustion is roughly equivalent to the CO2 absorbed by photosynthesis during its growth. Therefore, the carbon emissions of biomass combustion energy supply are relatively low, which helps to reduce the greenhouse effect. Biomass resources are widely distributed in nature, including agricultural and forestry wastes such as plant straw, corn cobs, rice husks, sawdust, and organic parts of urban garbage. However, biomass combustion will produce solid wastes such as particulate matter and ash, which may contain heavy metals and other harmful substances, easily causing water pollution and affecting the surrounding environment.
