摘要/Abstract

摘要： 液态空气储能技术是一种环境适应性好、容量大的电能存储技术,将液态空气储能技术与整体煤气化联合循环发电系统(IGCC)相结合,利用液空储能技术获取燃气轮机发电所需的高压空气,提高燃气轮机的出功,同时提高IGCC发电系统调峰、调频的能力,提高电能质量。本文从热力学角度出发,对该新型整体煤气化联合循环发电系统进行分析计算,建立系统物质和能量平衡,计算了系统的主要工艺参数。结果表明,净功率为150MW的液态空气-整体煤气化联合循环发电系统,燃气轮机净功率为95.9MW,汽轮机功率为53.9MW,系统热效率为52.8%;相同参数下未应用液态空气储能技术的整体煤气化联合循环发电机组功率为151.4MW,而传统简单循环燃气发电机组热效率仅为35.8%。

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 35.8%.
