摘　　要：随着全球温室气体浓度增加,气候环境逐渐变差,将影响人类可持续发展,因而节能减排显得越发重要。当前的技术水平下采用燃煤耦合生物质固废发电是种可行且经济的手段,项目组通过理论分析及工业应用,开发了多个燃煤耦合生物质固废发电应用工艺及关键设备,验证了利用300 MW循环流化床锅炉同时处理生物质200t/d、固废400 t/d、污泥200 t/d、RDF 50 t/d的可行性。为便于掺烧管理,开发了一种生物质直燃耦合发电系统,包括生物质输送给料系统、防作弊系统和数据分析集控系统,以便进行掺烧电量统计和避免掺烧作假。With the increase of global greenhouse gas concentration, the climate environment is getting worse. Climate change is one of the important reasons affecting the sustainable development of mankind. Energy conservation and emission reduction are becoming more and more important for the sustainable development of mankind. Power generation by coupling direct-combustion of biomass, solid waste and coal under the current technical level is a feasible and economic method. Through theoretical analysis and industrial application, the project team developed the coupling power generation technology and the key equipment. The feasibility of burning 200 t/d biomass, 400 t/d solid waste,200 t/d sludge, 50 t/d RDF in the 300 MW circulating fluidized bed boiler was verified. To facilitate the management of co-firing, a biomass direct combustion coupling power generation system was developed, including biomass feed system,anti-cheating system and data analysis centralized control system. Through these systems, the power counting could be realized, and the co-firing fraud could be avoided.
