摘要
IGCC系统中最主要的热回收装置之一是合成气回热换热器。由于经过了水洗等工艺,合成气回热换热器中的合成气不但具有一定的显热,而且其所含潜热量也是相当可观。对不同类型回热器、回热器的不同换热方式、回热器的不同布置方案的IGCC系统进行了分析和计算,根据能量梯级利用理论,采用专用的热平衡软件,综合考虑回热器对IGCC系统经济性、安全性、效率的影响,给出了全热回收方式IGCC系统中的合成气回热器的设计建议。
Syngas heat exchanger was one of the most important waste heat recover equipments in IGCC system. The syngas in the heat recover exchanger after being scrubed had a great deal of obvious heat and considerable latent heat. This paper analyzed IGCC systems with different types, different heat transfer modes and different layout schemes of heat recover exchangers, according to the theory of energy cascade utilization and using special heat equilibrium software, and considered the impact of exchanger on the economical efficiency, safety and heat efficiency of IGCC system, and gave reasonable design suggestions for whole heat recover exchanger in IGCC system.
