我国煤基电厂CO_2捕集技术发展的探讨

Discussion on the Development of CO_2 Capture Technology at Coal-fired Power Plant in China

介绍煤基电厂CO2排放的特征,并从燃烧前、燃烧后和富氧燃烧三个方面介绍了CO2捕集技术的特点。通过分析国内外煤基电厂CO2捕集技术的发展现状,提出我国煤基电厂CO2捕集的主要问题,指出适合中国国情的电厂CO2捕集发展方向。最后对我国全面开展煤基电厂CO2捕集技术基础研究和工业研究提出建议。

The paper first introduced the characteristics of CO2 emission from coal-fired power plant,and analyzed their related separation techniques,including pre-combustion,post-combustion and oxygen-enriched combustion.Meanwhile,it also introduced the situation and development of CO2 capture technology in China.Through the analysis of current situation,it put forward the main problem of Chinese CO2 capture technology in coal-fired power plant,and pointed out the better development direction of CO2 capture technology for existing pulverized coal plants.Finally,the route and direction of development of basic and industrial research in China are elaborated.
