摘　　要：园区级的清洁供热是目前综合能源服务中需要迫切解决的问题。多流程循环流化床技术采用"三床两返多流程"的结构设计,解决了传统的循环流化床锅炉小型化的问题。工业实践证明,多流程循环流化床锅炉可以选用生物质、工业固体废弃物、煤炭等作为燃料,针对多种燃料的热效率达到88%~92%,且污染物排放均达到了国家和地方标准中对排放浓度限值的要求。多流程循环流化床技术具有分散能源分散利用、多种燃料同时适用的优势,可以有效地为园区级的综合能源服务提供帮助。Park level clean heating is an urgent problem to be solved in integrated energy service. The multi-pass circulating fluidized bed technology adopts a three-stage furnace structure to form a two-stage material circulation in the furnace, which solves the problem of miniaturization of traditional circulating fluidized bed boilers. The industrial practice has proved that the multi-pass circulating fluidized bed boiler can use biomass, industrial solid waste, coal and other fuels. The thermal efficiencies of various fuels reach 88%~92%, and the emissions of the pollutants meet the required permissible effluent concentrations of the national standards and local standards. The multi-pass circulating fluidized bed technology has the advantages of decentralized energy utilization and simultaneous application of multiple fuels, which can be effectively applied to park level integrated energy service.
