水煤浆与煤粉燃烧脱硫比较

Comparison Between Desulfurization During Pulverized Coal Combustion and Desulfurization During Coal Water Slurry Combustion

以煤代油是能源工业的发展方向。作为新型代油燃料 ,水煤浆有广阔的应用前景。从硫析出特点、脱硫影响因素 (温度、Ca/S比 )以及烟尘排放等方面 ,研究了水煤浆燃烧脱硫与煤粉燃烧脱硫的异同。试验结果表明水煤浆燃烧脱硫优于煤粉 ,是值得推广的脱硫技术。

It is a trend to replace oil fuel by coal in the field of energy industry.CWS(coal water slurry) is a new substitute for oil fuel which has been widely used.In this paper the sulfur release,parameters of desulfurization (temperature,Ca/S ratio),particulate emission and so on were studied during CWS combustion.Compared with the desulfurization during PC(pulverized coal)combustion,the desulfurization during CWS combustion has a high SO 2 removal efficiency.The results prove that the desulfurization during CWS combustion is a good method of desulfurization.
