Crystalline structure of limestone calcination speed, the ash quality have a greater impact. Such as soft rock, marbled thin limestone, limestone calcite (CaCO3) crystal size is small, there is a gap between grain Shaanxi lime kiln construction, at a low temperature calcination volume expansion and difficult to break, easy to separate CO2 at high temperatures Plaza out of this limestone are more flammable, fine lime particles generated good activity; slope stone, rough marbled limestone contrary. When the temperature at 500 ~ 600 ℃, CaCO3 decomposition point has not been reached, because the limestone calcite crystal size of coarse, dense structure, due to the volume expansion cracked heat after they pass easily into pieces, fine, kiln will block the wind road, firing conditions worsen, the decomposition of CO2 escaping resistance big Anhui kiln construction, decomposition is slow, should not be used. Product rationalization fuel mix lime kiln fuel combustion Hubei construction, should not contaminate the product, or the degree of pollution in the quality of products within the allowable range. Therefore, when the calcination and firing high concentrate products, we must insist on the use of low-ash high calorific value gaseous fuel or liquid fuel. Because of China's unit GDP occupied by the fuel is too high, resulting in shortage of fuel resources, relatively speaking kiln construction, coal, less oil, blast furnace, coke oven, converter gas recovery, etc. inadequate use. From our actual situation, the focus of the work carried out: 1) the development of efficient coal preparation equipment, application of anthracite powder as kiln fuel; 2) utilization of coal resources, coal-water slurry as a refractory kiln fuel (> 1350 ℃ ); 3) the development of both the use of gas fuel and solid fuel, high calorific value and low calorie ene ene feed material and oxygen-enriched with two or with three burner technology.
