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。

Abstract:

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.

Key words: integrated energy service, multi-pass, circulating fluidized bed technology, biomass, industrial solid waste
