Rotary kiln calciner in operation, should always observe the instructions of the instrument data, the occurrence of anomalous, to timely find out the cause and take appropriate measures, measures need to be taken are the following: 1, the decomposition temperature of the furnace and the changes have taken place, indicating improper decomposition furnace oil to adjust fuel usage. 2, if the decomposition furnace oil does not change, the previous stage temperature is normal, is changed at a later stage, indicating a change in the volume of feed, the amount of change according to the feeding, adjusting the amount of fuel and secondary air. 3, if the decomposing furnace temperature is low, the high temperature levels preheater, calciner explain too much oil, through reduced oil or a way to increase secondary air temperature to be brought calciner, preheater at all levels temperature drop down. 4, the general case, the upper level and the lower level preheater preheater temperature is to maintain a substantially constant, if the temperature difference is reduced, indicating that material has to go short-circuit phenomena, such as: two normal temperature of 650 ° C, three normal temperature of 800 ° C, if the two temperature rises to 700 ° C, three temperature dropped to 700 ° C, illustrate two little, three materials, and this is due to a short circuit into three levels The results, which shows the need to adjust a discharge valve hammer, avoid cutting uneven, resulting in collapse of material short circuit. Pay particular attention to the operation, preheater, calciner, pipe seal, I heard the sound of air leakage, use alumina cement and asbestos rope seal block strict. Production Practice has proved that if the seal is not good, it will seriously affect the rotary kiln production and heat loss, the above article by Henan YuFeng Heavy Machinery (http://www.yufchina.com) collate published, reproduced, please indicate the source!
