摘　　要：介绍了一种利用溴化锂溶液的热力学特性,合理安排废热回收的废热溴化锂吸收式动力、冷、热量梯阶转换系统。该系统将其中一部分高品位的能量进行动力转换,其余转换成热量和冷量,实现能量梯阶转换,提高废热能源中可用能的合理利用率。利用自编的计算程序对系统的废热回收量以及能量利用与转换做了详细分析,得出烟气进出口温度对系统的能量转换的影响。A LiBr-H2O absorption cascading conversion system driven by waste heat for power,cool and heat was presented.The system transformed the high-grade energy into power and the relative low-grade energy into cool and heat so as to realize energy cascading conversion and improve the energy utilization of the available waste energy.Waste heat recovery,energy utility and its transformation were analyzed in detail by the self-designed computer program.Effect of the gas inlet or outlet temperature on the energy transformation was gained.
