The analysis of the heat loss causes of rotary kilnRotary kiln is that sulphur from the fuel, and, to a lesser extent from the limestone, can be expelled from the kiln in the kiln gases, without over-burning the lime, by a combination of controlling the temperature and the % CO in the calcining zone. Thus high reactivity, low sulphur limes can be produced using relatively inexpensive high sulphur fuels – subject to any emission limits for SO2 in the exhaust gases. During the use of rotary kiln, heat loss is a common thing, then how it happen? Here, Hongxing gives you a analysis of rotary kiln heat damage for several reasons.1. The thermal shockThe operation of kiln is unstable and kiln operation is not normal. The kiln surface collapses suddenly, and the brick temperature is soaring, even close to a megawatt-hour, kiln frequently open and stop frequently produce thermal stress in the brick, brick internal absorption heat stress ability has certain limits, once beyond its structural strength, brick and structure weakened expands unceasingly deeply, and making brick pieces. Kiln vanishes in the rubble of the hot surface, and makes the brick damage over-time.2. The overheatingThe heat load o rotary kiln is too high, above the refractoriness load, kiln surface could not form. Brick skin for a long time lost protection by kiln surface, brick eutectic impurity in the high temperature melting, the migration direction of cold front layer, are permeable bed close-grained, leaving the hot surface is porous. Porous thermal coat wear no brush, collision and shock and thermal fatigue, easy to damage.Henan Hongxing Mining Machinery Co., Ltd. y specializes in the production of lime kiln, cement rotary kiln, rotary kiln equipment and lime, cement, mineral processing production line equipment.
