兰炭粉末与电石炉尾气混烧石灰窑的研究

摘要

在煅烧石灰用煤粉和电石炉尾气双燃料混烧双梁式石灰窑的基础上，对炭材干燥过程中产生的兰炭粉末进行回收，用兰炭粉末代替煤粉煅烧石灰，不仅可以使电石炉尾气和兰炭粉末得到充分的回收利用，而且还可以降低生产成本，产生很大的经济和社会效益。%Based on the basis of double beam lime kiln which was burned with double fuels of coal powder for lime calcined and exhaust of calcium carbide furnace ,semi-coke powder was recycled in drying process of carbon material .Replacing coal powder with semi-coke powder in lime calcination not only can fully recycle the exhaust of calcium carbide and semi-coke powder ,but also can reduce the production cost and make a great deal of economic benefit and social benefit .
