摘要
介绍了清华大学提出的"基于吸收式循环热电联产集中供热技术"在大同煤矿集团公司"两区"供热中的应用,通过一个采暖期的运行数据与测试分析表明,该系统运行稳定可靠,热能利用效率高,热力站的吸收式换热机组能够将一次网回水温度降到25℃左右,同时电厂的余热回收热泵机组可回收电厂循环水余热,两者结合运用,节能与经济效果显著。
This paper introduces the application of district heating system based on co-ah cycles,proposed by Qinghua University,in combined heating and power systems in Datong Coal Mine Group.Analysis on running data of a whole running season showed that the system ran stably and increased energy efficiency significantly.In the heating substations,the temperature of return water is reduced to 25℃ by absorption-exchangers.In the cogeneration plant,circulating water is heated by extraction steam of steam turbines and exhausted heat in absorption pumps.This system achieves a high energy saving effect and economic benefit,so it is proper to apply this system in large-scale.
