Abstract:

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.
