为解决煤矿用热需求不断增大而电厂能量转化过程中热利用率较低这一矛盾,采用搭建的专门热泵试验检测平台进行电厂辅机冷却水余热回收运行模拟试验研究。通过试验掌握了电厂辅机冷却水水量、水温及蕴含的能量等参数,测试了电厂辅机冷却水废热回收的运行工况,为电厂辅机冷却水废热回收的工业应用提供了理论基础。研究表明:模拟运行末端室内温度达33～35℃,洗浴热水温度达45～50℃,热风出风口温度50～55℃,能够满足煤矿洗浴热水以及建筑冬季采暖等用热温度需求。

In order to solve to the contradiction between the thermal requirements increased continuously in coal mine and the low thermal utilization of the energy conversion process in the power generation plant, a special heat pump experiment measuring platform was established to the study on the simulation experiment of wa ste heat recovery operation from the cooling water of the auxiliaries in the power generation plant.With the experiments, the cooling water quantity, water temperature, potential energy and other parameters of the auxiliaries in the power generation plant were mastered, the operation performances of the cooling water heat recovery of the auxiliaries in the power generation plant were measured and those provided the accurate theoretical basis to the industrial application of the cooling water heat reco very of the auxiliaries in the power generation plant.The study showed that the indoor temperature at the operation end of the simulation reached at 335 °C, the bath w ater temperature reached at 4550 °C and the temperature at the heat ventilation outlet reached at 5055 °C.All those could meet the mine bath hot water, the heating sup ply of the buildings in winter and other heating requirements.
