摘要

采用GT PRO软件分别建立了基于GE-Texaco及Shell气化技术的IGCC电站模型

利用余热锅炉高压省煤器不饱和水预热清洁合成气

考查预热清洁合成气对IGCC电站能量分配、发电容量、供电效率及净热耗率等性能的影响。模拟计算结果表明

预热清洁合成气后GE-Texaco IGCC和Shell IGCC电站的净发电量占总输入能量的比例分别提高了0.2%和0.3%;电站总输入能量分别降低了26 MW和25 MW;电站供电效率分别提高了0.26%和0.36%

净热耗率分别降低了51kJ/(kW·h)和56kJ/(kW·h)。预热清洁合成气有利于改善IGCC电站的整体性能。

Abstract

The GE-Texaco and Shell gasification technology based model of the IGCC power station was established by using the GT PRO software.The unsaturated water extracted from high pressure economizer of waste heat boiler was adopted to preheat the clean syngas

to investigate its influence on such performance as energy distribution

power generation capacity

electricity supply efficiency and net heat consumption rate of the IGCC power station.The simulation results showed that

after the clean syngas was preheated

the proportion of net generation of the GETexaco and Shell IGCC power station to the total input energy increased by 0.2%and 0.3%

respectively;the total input energy of the above two power stations decreased by 26 MW and25MW;the electricity supply efficiency of them rose by 0.26%and 0.36%

and the net heat consumption rate dropped by 51kJ/(kW·h)and 56kJ/(kW·h)

respectively.This indicates that preheating syngas can enhance the overall performance of IGCC power stations.
