Double-beam lime kilns are fit for many kinds of fuel, waste less energy and have high activity.For simple structure and Iow cost, they are widely used for iron and steel,and chemical industries to calcine high quality active lime,using blast furnace gas,coke oven gas and coal dust to raise lime quality and save energy.This kind lime kiln has been registered,gained the national patent and to be used widely in large iron and steel enterprises and chemical industries throughout the whole country.I. Technical features:1. Production capacity:lOOt/d to 600t/d. Operation range is 70% to 100%. Take the 300t/d kiln as example.It can be regulated within 180t/d-300t/d range without influencing quality and consumption targets。2.fuel: natural gas, oil, coal dust, coke oven gas, coal gas of low heat value(e.g pure blast furnace gas ) and mixed fuel of all kinds of fuel(gas and gas, gas and liquid gas and solid, liquid and solid and so on).3.Lime: fine lime and high activity (reaching 360ml, 4N HCL Ten minutes). The ratio of lime stone under-firing and over-baking is 3%-6%. 5.Low heat wastage.
