燃煤低氧燃烧硫化物析出特性试验研究

The Experimental Research on Coal Combustion Sulfur Release Under the Combustion with Low Oxygen Content

在低氧燃烧条件下,通过研究变氧浓度对燃煤SO2、H2S析出速率和析出量的影响以及与燃煤分别在空气和惰性气氛下燃烧和热解进行比较,得出了硫析出的规律。为燃煤电站在低氧运行条件下控制SO2排放和消除高温腐蚀提供一定的理论依据。

Under the combustion with low oxygen content, the conclusion of coal combustion sulfur release is obtained by studying the effect which the changeable oxygen concentration have on the velocity and quality of SO2 ,H2S release, and comparing with the coal combustion sulfur release under the combustion and pyrolysis with air and inert gases. The direction is provided for the coal combustion power plant to control the SO2 emission and eliminate high temperature erosion under the combustion with low oxygen content.
