摘要
针对已在125MW及300MW等级火电厂中投产的大型吸收式热泵系统的变工况热力特性进行试验测试,并分析其试验数据,对吸收式热泵系统在驱动蒸汽压力、热网水回水温度、余热水进水温度等主要外部条件和参数变化条件下的运行指标进行了测试和分析,从而获得了这些主要外部参数改变对吸收式热泵制热能力、余热回收量、能效比等重要指标的定量影响。该试验结果为采用大型吸收式热泵系统进行电厂冷凝热回收供热改造工程的初期设计及投产后的优化运行提供了第一手参考资料。
An experiment on waste heat recovery thermal characteristics from circulating water in 125MW and 300MW thermal power plants using large absorption heat pump is conducted. The steam pressure, the temperature of the backwater from heat-supply network, the inlet circulat- ing water temperature of the large absorption heat pump sys- tem are analyzed under other external conditions and differ- ent parameters. Then the effects of main external parame- ters on heating capacity, the recovery of residual heat, en- ergy efficiency ratio and other important indicators in the large absorption heat pump are quantitatively discussed . The conclusion provide the firsthand information for the de- sign of the waste heat recovery engineering and regular op- eration of large absorption heat pump.
