Ha pan biomass power generation technology including direct combustion biomass power generation technology and mixed combustion power generation technology, including biomass direct combustion power generation technology and biomass fluidized bed boiler grate furnace technology, mixing combustion power generation technology including the coupling of biomass gasification power generation and direct coupling technology, such as power generation technology has a large number of engineering performance, some units have been running more than ten years, mature technology and reliable, The power generation power of a single unit covers 15~40MW, and the unit parameters cover the reheat units with medium temperature and pressure to ultra-high temperature and ultra-high pressure. The fuel includes all kinds of agricultural and forestry wastes such as straw, rice husk, wood block and bark. The boiler is designed according to the characteristics of biomass fuel, and the key technologies such as the stability of the boiler feeding system, the corrosion resistance of the unit heating surface, and the emission control of pollutants are mastered. The boiler design is optimized by using CFD numerical simulation technology. The unit runs steadily, and the annual utilization hours can reach more than 8000 hours. The Datang Changshan Biomass Gasification Coupled Power Generation Project contracted to build is a national biomass coupled power generation demonstration project. A single 30MW biomass generator set can consume more than 200,000 tons of agricultural and forestry biomass within 50 kilometers of the surrounding area each year, satisfying the large-scale consumption and utilization of biomass resources, which has broad application prospects in the future.
