YuFeng interpretation kiln preheater kiln blockage reasons

Article source：

Cement Kiln in the production process is the most common malady preheater blockage and crust. This not only affects the quality of the clinker, but also directly affect the safe operation of the kiln cycle. The main reason analysis to produce such situations are: the impact of raw materials and fuel, and factors affecting the operation of the equipment considered. Influence the impact of raw materials and fuel raw material composition of the raw material flammability KH raw material influence on the maximum. Jaw crusher control when raw meal is low, if not promptly adjust the calcination temperature, can lead to crust, clogging. When the water is high pulverized coal fineness, also have a similar situation. When the ash content of coal is changed, the amount of coal fuel in the sintering process used to increase the speed of coal combustion and causes severe reduction atmosphere, resulting crust preheater plug. The impact of harmful ingredients harmful ingredients mainly refers Na2O and K2O, in the clinker calcination process, the harmful ingredients in the kiln system cycle, gather. Once the content is too high, then the chemical reaction with other components, thereby reducing the amount of liquid phase formation temperature. When the temperature is lowered to the extreme, resulting crust phenomenon. Human impact of coal caused by improper operation, with no material at high temperature Dangdang calciner, feeding amount not timely follow, resulting in a small amount of liquid material soon appear at high temperatures to form crust. When decomposing furnace temperature is low, so that can not be pulverized coal into the furnace combustion or incomplete combustion, so that local overheating four cylinder formed crust. Thermal system is unstable when the kiln is not functioning properly, thermal system instability, slow kiln when needed, so that the material deposited on the kiln, resulting in delivery is not timely, resulting in under four cylinder tube blockage. Crust, clogging a precaution, strictly control the quality of raw materials and fuels. 2, the thermal stability of the kiln system to ensure that organic complexes wind, coal, material. 3, strengthen the management of the kiln system, focus on doing the work to seal plugging.
