摘要
利用吸收式热泵来减少热电厂排汽损失,不仅能提升机组供热能力,同时能给企业带来一定经济效益。对于热泵组长期运行中发现的一些问题,提出加强热泵系统参数的监视和检查的建议,并针对热泵蒸发器水室和传热管内部结垢、余热水入口温度及流量调整、热泵加热蒸汽压力及温度调整等方面提出了具体措施。
Absorption heat pump is used to reduce the exhaust steam loss in thermal power plants,which improves the heat supply capacity of units and brings economic benefits to enterprises.In allusion to some problems in the long-term operation of heat pumps,suggestions are proposed for more supervision and inspections on the heat pump system parameters,as well as specific countermeasures for dealing with the scaling anomaly inside the evaporator water chambers and heat transfer tubes of heat pumps,the inlet temperature and flow adjustment of residual hot water,and the pressure and temperature regulation of steam heated by heat pumps,etc.
