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。
The globe and detailed mechanism of H2S 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(MH&AS)combustion technology is proposed to restrain the H2S formation.The primary experimental results show that,the MH&AS technology not only can realize low NOx emission and high efficient combustion,but also inhibit the formation of H2S on the water cooled wall surface.Furthermore,it suggests that the future research should focus on improving the globe reaction mechanism for H2S 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.
