蒸汽水合生石灰的脱硫实验研究

Experimental Study of the Desulfurization Performance of Calcium Oxide Activated by Steam Humidification

在烟气增湿脱硫实验台上 ,进行了蒸汽水合生石灰的脱硫实验研究。结果表明 ,钙硫比、饱和温距 (烟气温度与水蒸气露点的温差 )ΔT和烟气流速 (停留时间 )是影响脱硫效率的主要因素 ,合理地配置这些因素能够有效地提高脱硫效率。

On a test rig of flue gas humidification and desulfurization an experimental study was conducted of the desulfurization performance of calcium oxide activated by steam humidification. The study results indicate that a whole range of parameters, such as Ca/S molar ratio, approach to saturation temperature (temperature difference between flue gas and water steam dew point), flue gas flow speed (residence time), exercise a major influence on the desulfurization efficiency. A rational allocation of the above parameters can result in a significant enhancement of the desulfurization efficiency.
