本文报道了国内首台工业规模的吸收式热转换器（AHT）设备对北京燕山石化公司合成橡胶厂冷凝段98℃蒸汽和有机蒸汽混合气释放的余热进行回收的试验结果。回收的热量用于将热水从95℃加热到110℃，作为补充热源反馈到混凝器。AHT系统使用H2O/LiBr溶液运行，热流为5000 kW。给出了AHT系统的性能系数、热效率和温度升程。通过实验数据与模型计算结果的对比，说明了AHT各部件（吸收器、发生器、蒸发器、冷凝器和液液交换器）的换热特性。结果表明，平均COP为0.47，可实现总温升25℃，投资回收期约为2年。2003爱思唯尔科学有限公司版权所有。
This paper reports the test results of the first industrial-scale absorption heat transformer (AHT) equipment in China, to recover the waste heat released from mixture of steam and organic vapor at 98degreesC in coacervation section, synthetic rubber plant of Yanshan Petrochemical Corporation, Beijing, China. The recovered heat is used to heat hot water from 95 to 110degreesC, feeding back to the coagulator as the supplementary heating source. The AHT system is operating with H2O/LiBr solution with heat flow of 5000 kW. The coefficient of performance (COP), the thermal efficiency and the temperature lift of the AHT system are presented. The heat transfer characteristics of the AHT components, i.e. absorber, generator, evaporator, condenser and the liquid liquid solution heat exchanger, are also illustrated by comparison of experimental data and the model calculated results. The results show that the mean COP is 0.47, the gross temperature lift of 25degreesC can be realized and the payback period is approximate to2 years. (C) 2003 Elsevier Science Ltd.
