摘要

本文提出了一种创新的煤气化发电系统，即用气化后的煤燃料煤气产生的1300 K左右的高温空气气化煤。这些系统的主要特点是热效率高，低NO/sub /排放，紧凑的脱硫和除尘设备以及使用非常紧凑的气化炉高效地去除熔渣。本文报道了适用于高温空气煤气化的球床煤气炉的实验结果，球床成功捕获了97.7%的煤灰，并无堵塞提取。提出了一种高可靠性、低成本的高温空气预热系统的新概念。

Innovative coal gasification system with high temperature air

This paper proposes innovative coal gasification power generation systems where coal is gasified with high temperature air of about 1300 K produced by gasified coal fuel gas. The main features of these systems are high thermal efficiency, low NO/sub x/ emission, compact desulfurization and dust removal equipment and high efficiency molten slag removal with a very compact gasifier. Experimental results on the pebble bed coal gasifier appropriate for high temperature air coal gasification are reported, where 97.7% of coal ash is successfully caught in the pebble bed and extracted without clogging. A new concept of high temperature air preheating system is proposed which is characterized by its high reliability and low cost.
