Quick burning of cement kiln thin material.Txt
Quick burning of thin material
The fast burning of thin material can fully utilize the high activation energy of the new ecological CaO produced by the decomposition, and can improve the crystalline morphology of silicate minerals in cement clinker, improve the hydration activity of clinker minerals and strength of clinker. Kiln speed faster, the material is raised higher and higher, better contact material and hot air flow inside the kiln, the heat transfer efficiency is high; the faster the kiln, materials and materials, materials and the kiln temperature difference is small, so the bonding materials and materials will be less, not easy to ring, heading, hang long kiln skin phenomenon the kiln; the faster the supporting oil film formed between wheel and tyre is more uniform, better lubrication effect, prolong the life of roller and tyre.
On the other hand, because of the fast burning of thin material, the hot gas flow in the kiln is fast and the heat consumption is high. The thermal intensity of the kiln flame must be improved so as to ensure that the firing has enough firing temperature. However, it is not the sooner the better the kiln speed, otherwise the coal consumption of tons of clinker will be greatly increased.
2 full capacity production
As the core equipment of decomposing furnace technology decomposition, its main function is to complete combustion of pulverized coal and raw meal decomposition rate of 85%95% furnace. The best matching of the production wind, coal and material at full load is beneficial to the stability of the reaction and decomposition reaction of the decomposition furnace, to improve the benefit, and to reduce the coal consumption and electricity consumption of the ton clinker. In operation, the volume of feed is larger, the total air volume is larger, can increase the oxygen content in the kiln, improve two air temperature, the powerf
