流化床锅炉单、双辅机布置运行方式及经济性比较

Analysis of Operation Mode and Economical Efficiency for Single Equipment Boiler and Double Row Equipment Boiler

对甲、乙2个火电厂流化床锅炉分别采用的单辅机、双辅机布置的运行方式及经济性进行比较。采用锅炉单辅机布置的机组,在风机投资及建设维护方面,比双辅机布置的机组可一次性节省较大费用,但在运行可靠性方面略低于双辅机布置的机组,因此单辅机布置的机组在风机选型上要合理。通过对比,为CFB锅炉的烟风系统、辅机设计、布置选型及节能改造提供技术参考。

Make comparision of operation mode and economic benefit between single equipment boiler and double row equipment boiler. The investment and construction maintainance of the single equipment boiler has an advantage over double row equipment, companies can save a lot of costs, but equipment operational reliability to be worse. So it should be reasonable when choose single equipment boiler wind turbine equipment. Through comparison, the author prefers to take technical reference for the CFB boiler flue gas system, auxiliary design, layout selection and energy-saving.
