摘要

本文综述了H_2S生成的总包反应机理和详细反应机理

分析了相关研究中还需进一步解决的问题。在此基础上

提出了多孔壁风耦合空气燃烧技术

以抑制煤粉燃烧过程中H_2S的生成。初步的实验结果表明

该技术可望在实现低NO_x排放和高效燃烧的同时

有效抑制水冷壁面附近H_2S的生成。今后的研究应集中在完善H_2S生成的总包反应机理、修正其详细反应机理及构建简化机理

并论证多孔壁风耦合空气分级燃烧技术优势。

Abstract

The globe and detailed mechanism of H_2S formation during pulverized coal combustion is reviewed in detail

and the problems of the current studies are pointed out and analyzed. Moreover

the multi-hole wall air coupling with air staged(MHAS) combustion technology is proposed to restrain the H_2S formation. The primary experimental results show that

the MHAS technology not only can realize low NO_x emission and high efficient combustion

but also inhibit the formation of H_2S on the water cooled wall surface. Furthermore

it suggests that the future research should focus on improving the globe reaction mechanism for H_2S formation

modifying the detailed reaction mechanism

constructing the simplified mechanism

and demonstrating the advantages of the air-staged combustion technology with air-coupled porous wall.
