炼焦煤指标(国外英文资料)Gas coalGas coal is the most coal-burning coal, which is non-binding or microcaking. Not coking in a laminated coking oven. When it burns, the flame is short and it burns.A kind of coal. The coal and appellation of coal that is less coal.It can be coking and can be used as the raw material. But because of weak caking property, thermal decomposition generated when a large number of gas and coal tar, coke shrinkage degree is big, the crack is more, must match the coking coal, fat coal, etc., in order to improve coke quality.The gas coal is made up of two parts: the first one is dry and non-grey, the volatile component Vdaf 37%, the bonding index G 35, the maximum thickness of the glue layer is less than 25mm coal. This type of coal is characterized by a particularly high volatility and low viscosity. The second category is Vdaf , 28% ~ 37%, G , 50 ~ 65 coal. It is characterized by high volatility and medium viscosity.It is one of the components of coking and coal, and can also be used as power for coal, gasification and coal. It can also be used as raw material for industrial materials such as gasification and low temperature dry distillation.It can also be used as a locomotive, a generator, an industrial boiler, a recycled kiln for cement and a gas from the city.Coking coalThe first type of coking coal is dry and ash-free, the Vdaf 10% ~ 28%, the bonding index G 65, the maximum thickness of the gum layer, and y is less than 25mm. This part of coal is extremely coking, which can be used separately to produce a qualified blast furnace coke.The other type of coking coal is dry and ash-free and the volatile component Vdaf 20% to 28%, and the bonding index G , 50 ~ 65, is worse than the former. Coking coal has medium volatile and good adhesion, which is typical coking coal, which can form a good colloid when heated. When coke is made separately, it can get a large, crack, and crushing strength, and it is good for abrasion. However, the resulting expansio
