Abstract
Liquid air energy storage (LAES)is a novel electric energy storage technology,with advantages such as excellent environmental adaptability and high capacity.This paper combined LAES technology with IGCC system.Compared to the old ones,the advanced LAES-IGCC power plant has better performance in power quality control and peak shaving.It uses LAES technology to obtain high-pressure air for power generation.In this paper,a thermodynamic analysis is presented for such a system.The mass and energy balance of the power plant was calculated,and the key process parameters of the system and all reactors got optimized.The results showed that a 150MW LAES-IGCC power plant could work normally with thermal efficiency of 52.8%.In addition,gas turbine power and steam turbine power of this system is about 95.9MW and 53.9MW,respectively.Correspondingly,power of a traditional IGCC system without LAES is about 151.4MW with the same parameters,while a simple cycle gas turbine with thermal efficiency of only 3 5.8%.关键词
