摘要
为回收炼厂丰富的低温余热用于生活区的集中供暖,本文对余热资源和生活区采暖热负荷分别进行了综合标定和统计计算,确定采用回收余热、汽暖改水暖的集中供热系统方案。技术经济分析表明,该方案的节能效果和经济效益十分显著。
In order to recover and utilize the low temperature waste heat from large refinery to satisfy district heating for residential buildings,composition survey and statistic calculation of waste heat resource and heating load of residential buildings are respectively carried out in this paper.Then district heating system with hot water from waste heat recovery instead of steam is determined,and the optimal insulation structure of directly buried pipe is discussed.The cost-effectiveness analysis shows that the energy -saving effect and economic performance of this project are very notable.
