水泥窑筒体余热回收热电冷联产分析

Analysis of CCHP in Waste Heat Recovery of Cement Kiln Shell

该文从现有的水泥生产线回转窑筒体余热回收技术背景出发,介绍了回转窑筒体散热及回收利用情况,同时采用热电冷联产,夏季采用溴化锂吸收式制冷机组制冷,冬季产生热水供暖,过渡季采用闪蒸技术提高余热发电系统发电量,从而更加合理的利用回转窑筒体散热。

This paper starts from the waste heat recovery technology for rotary kiln shell in existing cement production line,introduces heat dissipation and recycling of rotary kiln shell.By adopting the cogeneration cooling heating and power,in summer,lithium bromide absorption refrigeration unit is used for refrigeration,while hot water is generated for heating in winter.In transition season,flash evaporation technology is used to improve the electricity generation output of waste heat power generation system,thus making more reasonable use of heat dissipation of rotary kiln shell.
