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.
