清洁煤发电的CCS和IGCC联产技术

煤气化联合循环(IGCC)发电技术是煤气化和燃气—蒸汽联合循环的结合,是当今国际正在兴起的一种先进的洁净煤(CCT)发电技术,其具有高效、低污染、节水、综合利用好等优点。碳捕捉及封存技术(CCS)和整体煤气化联合循环技术(IGCC)被认为是最有潜力的技术。这里简要介绍了整体煤气化联合循环(IGCC)系统、构成及发展现状,总结了二氧化碳的收集方式和封存方法。指出了成本问题是困扰CCS和IGCC的联产应用的主要障碍。

Clean Coal Power Generation, CCS and IGCC Caol Power Techology

IGCC power generation is a combination of coal gasfication and gas-steam-turbine combined circlation generation. Combining with CCT, IGCC is a springing up advanced clean coal power generation techology with advantages of high efficience, low pollution, water saving. IGCC combined with CCS is considered to be a potential generation technology. Here the structural system, configuration and recent utilitis is introduced in brief. The collection technique of CO2 is concluded as well. The high cost of IGCC, the reasons that baffles its application is pointed out.
