ORC与SRC余热发电系统的选型原则

Selection Principle of ORC and SRC Technology in Waste Heat Recovery System

介绍了ORC余热发电技术国内外发展现状。ORC余热发电系统是以低沸点有机物为工质的朗肯循环,是一种可以将低品位热能高效转化为电能的余热发电技术,主要由烟气余热回收系统、导热油—有机工质热交换系统及有机工质发电系统三部分组成,其工作原理与SRC余热发电系统相同。通过对比不同条件下ORC和SRC余热发电系统的构成和发电效率,提出了ORC和SRC余热发电系统的选型原则。

The current status of ORC waste heat power generation technology at home and abroad is introduced.The ORC waste heat power generation system is a Rankine cycle with low-boiling organic matter as the working fluid.It is a waste heat power generation technology that can efficiently convert low-grade thermal energy into electrical energy.It is mainly composed of three parts:the flue gas waste heat recovery system,oil-organic working fluid heat exchange system and organic working fluid power generation system.Its working principle is the same as that of the SRC waste heat power generation system.By comparing the composition and power generation efficiency of ORC and SRC waste heat power generation systems under different conditions,the selection principles of ORC and SRC waste heat power generation systems are proposed.
