新型复合动力/制冷循环空冷系统电站的经济分析

Economic Analysis on the Combined Power/Refrigerating Cycle Air Cooling System in Power Plant

当前,电力行业的发展面临节能减排的压力。简要回顾动力循环优化和提高热能综合利用方面的工作,对前期提出的复合动力/制冷循环电站空冷系统(以下简称复合循环空冷系统)进行经济分析,并分析其节能减排的贡献。以压缩制冷复合循环空冷为例的模拟计算表明复合空冷系统的可行性,指出新形势下空冷系统面临的重新选择,间冷系统将会受到重视和发展,采用制冷剂的复合动力/制冷循环空冷系统将成为一种新的选择。

At present,the development of power industry is facing the pressure of energy saving and emission reduction.The strategy for development in optimizing power cycle and improving comprehensive utilization of heat energy were revieved.A economic analysis was made to the combined power/refrigerating cycle air cooling system(hereinafter called 'combined cycle air cooling system') which presented previously and estimated its contribution to energy saving and emission reduction.An analog computation example shows that the combined cycle air cooling system based on the compression refrigeration is feasible and effective.Finally,the air-cooling system is facing the re-selection under the new situation was pointed out,the indirect air-cooling system will be of importance to the development,and the combined cycle air cooling system will become a kinds of new options.
