摘要
结合热力学第一、第二定律,阐述了小型工业汽轮机引入热电联产系统的基本特性,并以某热电厂为例,给出了小型工业汽轮机驱动给水泵及供热系统循环泵的能量梯级利用的分析方法。结果表明,合理利用工业汽轮机驱动给水泵及循环水泵使循环的尽可能地得到利用,有利于热电厂的能量转换和提高电厂的经济性。
Based on the thermodynamics＇ First Law and Second Law, the fundamental characteristics of heat-exergy transfer and the relation and difference between heat transfer and heat-exergy transfer were analyzed. The general exergy analysis model for exergy transfer process analysis for a cogeneration system in which the feed-water pump and the heating system cycle pump were driven by small industrial turbines was given. The analysis showed that reasonable utilization of small industrial turbines to drive the feed-water pump and the circulating pump could help make full use of the circulating exergy, which was beneficial to energy transformation and economy improvement for cogeneration plants.
