DEVICE FOR PREVENTING FORMATION OF DEPOSITS IN GAS CIRCULATION LINE OF BACK-END BATCH KILN

摘要

PURPOSE: Provided is a device for preventing the formation of deposits in a gas circulation line of a back-end batch kiln, which facilitates the gas circulation, prevents the overconsumption of fuels, and increases the heat efficiency and productivity. CONSTITUTION: The device comprises: a circulation gas puzzy nozzle(59) which supplies a circulation gas puzzy second air(58) at a high speed so as to the powdery lime stacked at the inside of the gas circulation line of the back-end batch kiln toward the inside of a middle barrel(25); and a circulation gas puzzy controlling valve(57) which is disposed on the circulation gas puzzy nozzle(59) to control the supply of the circulation gas puzzy second air(58) periodically.
