资料简介

在世界范围内,基于 高效煤气化技术,是商业或半商业操作,少数 更多的项目正在建设中,还有一些示范项目,包括碳捕获 而隔离(CCS)则处于规划的高级阶段。各种煤气化技术 这些工厂包括不同的供煤系统(干煤或煤浆),防火内部 墙体(耐火砖或水冷管)、氧化剂(氧气或空气)和其他因素。其中许多 现在设计已经有几十年的历史了,但是新的周期和系统正在出现,以进一步改进 煤气化过程的效率。这份报告借鉴了已发表的文献, 工业界和学术界在煤气化行业工作的专家评论如下 并总结近期的发展动态。

Worldwide, a small number of integrated gasification combined cycle power plants (IGCC), based on high-efficiency coal gasification technologies, are operated commercially or semi-commercially, a few more are under construction, and a number of demonstration projects, some including carbon capture and sequestration (CCS), are at an advanced stage of planning. Various coal gasification technologies are embodied in these plants including different coal feed systems (dry or slurry), fireproof interiors walls (fire brick or water-cooled tubes), oxidants (oxygen or air), and other factors. Many of these designs are now several decades old but new cycles and systems are emerging to further improve the efficiency of the coal gasification process. This report draws upon the published literature and commentary from experts in industry and academia working in the coal gasification sector to present and summarise recent developments.
