摘要

介绍常规燃煤电厂两种CO2排放控制技术

即利用吸收溶剂对锅炉烟气进行选择性吸收分离技术及富氧燃烧技术

分析两种技术导致电厂效率下降的因素

推导出电厂净效率计算公式。以600 MW燃煤机组为例进行了实际计算

结果表明:采用上述两技术后

电厂的净效率分别为22.55%和27.25%。同时

指出了能量损失的原因和改进的方向。

Abstract

Two technologies for controlling CO2 emission from conventional coal-fired power plants

i.e.selectively absorbing technology for separating CO2 from flue gas by using absorbing resolvent

and oxygen-enriched combustion technology

have been presented

the factors leading to decrease of power plant efficiency in using the said two technologies being analysed

and formula for calculating the net efficiency of power plant being deduced.Taking the 600 MW coal-fired unit as example

the practical calculation has been carried out

results show that the net efficiency of power plant after adopting above-mentioned two technologies to be 22.55% and 27.25% respectively

at the same time

the causes leading to energy loss and directions for improvement being pointed out.
