Two-way combustion method with normal and reversal combustion is a new type of practical technology, with which clean combustion of bitumite-moulded coal can be realized. This paper will discuss the experimental results about the mechanism of eliminating smoke, distribution of temperature field, evolution regularities of volatile matter and fuel sulfur,and sulfur capturing characteristic when burning bitumite-moulded coal with the technology mentioned above.

正、反烧相结合的双向燃烧法是实现烟煤型煤洁净燃烧的新型实用技术。本文论述采用双向法燃烧烟煤型煤时的消烟机理、温度场分布、挥发分析出规律、燃料硫的析出规律与固硫特性的试验研究结果。

in this paper we give a review of removal of hydrogen sulfide(H 2S) and sulfur dioxide(SO 2) by adsorption method (dry method).First,we point out that fossil fuels are main source of sulfur;then explain the chemical principles for removal of H 2S and SO 2;next,lay emphasis on two kinds of adsorbents.One is used in hot gas cleanup of coal gas in IGCC plants;the other is in simultaneously desulfurization and denitrification of flue gas.In the end,we show the factors that may affect the choosing of adsorbents....
