摘要
针对整体煤气化联合循环(IGCC)总的热效率没有得到充分提高这一问题。为了获得更高的发电效率,发展了先进的IGCC技术,而此种技术是基于回收概念基础之上的。从IGCC整体系统与设备结构看来,这种技术将发电先进技术合为一体化,综合利用当前的发电技术,并通过蒸汽在气化炉内的吸热反应,回收燃气轮机或固体氧化物燃料电池的排气热。据估计,这种回收利用具有易于使用、分离、收集固定CO_2的效果使其非常具有吸引力,并且可以提高总效率的10%甚至更高。研究整体煤气化联合循环发电系统的核心设备之一的流化床气化炉的特征性能,以及它对整个系统的作用和影响。
The overall thermal efficiency of the integrated gasification combined cycle（ IGCC） has not been sufficiently improved. In order to achieve higher power generation efficiency,the advanced technology of IGCC has been developed which is on the basis of the concept of exergy recovery. IGCC systems and devices from the overall structure of opinion,this technology will generate electricity for the integration of advanced technology together,the current utilization of power generation technology and by endothermic reaction of steam in the gasifier,a gas turbine exhaust heat recovery or the solid oxide fuel cell. It is estimated that such the use of exergy recycling has the advantage of being easy to use,separating,collecting fixed CO2,making it very attractive,and can increase the overall efficiency by 10% or more. The characteristics of fluidized bed gasifier,one of the core equipment of the IGCC system,and its effect on the whole system were studied.
