摘　　要：针对迁安中化采用蒸汽作为采暖热源存在的暖气组温度高、风险大,蒸汽浪费等问题,进行了循环氨水余热利用项目改造,通过设计循环氨水采暖换热器,采用采暖水闭式循环,增加自动监测及补水系统等措施,用循环氨水替代原有蒸汽供部分区域采暖,提高了采暖的安全性,实现了节能减排,每年节约蒸汽费用129.6万元。In response to the high temperature risk,difficulty in controlling the indoor temperature,and high steam loss caused by the use of steam as a heating source in Qian′an Zhonghua Coal Chemical Co.,Ltd.,a renovation project for the utilization of waste heat from circulating ammonia water was carried out.By designing a circulating ammonia water heat exchanger for heating,adopting a closed loop heating water system,adding automatic monitoring and water replenishment systems,etc.,circulating ammonia water was used to replace the original steam for heating in some areas,thus improving the safety of heating,achieving the energy conservation and emission reduction,and saving the steam cost by 1.296 million yuan annually.
