![]() Kiln feed has been uneven impact
Kiln incoming instability to produce an enormous impact, I plant based on years of practical experience, summed up the kiln feed to avoid unstable approach. Kiln
when the feed is higher, there will be pressure kiln appeared cyclone exit and calciner temperature, kiln temperature would drop dramatically, and you should be appropriately reduced kiln speed, reducing the volume of feed, open a large exhaust, stretch into the pulverized coal burner, which can improve the kiln temperature to strengthen materials burn effects; may also be appropriate stokers, but never too much, otherwise it will result in a reducing atmosphere, the kiln temperature lower. When the kiln owners pass motor current decreased rapidly, to reduce kiln speed, quit coal burner, the appropriate transfer a small amount of exhaust, this time can be acute and short flame burning, so back to normal. When the kiln after normal working conditions, and then feed, do not feed tiouine, it would operate in a passive state, production, quality is also very difficult to guarantee. When the kiln feed less , should not be pulverized coal injection tube into it, open a large exhaust, elongated flame, it would be a sharp increase in temperature kiln, calciner, cyclone temperatures will soon rise, thereby vulnerable to cyclones or unloading pipe bonding or even blocked, kiln calciner smoke chamber and also easy crust, and the system resistance increases. The correct way is to appropriate some of the pulverized coal burner out back, off a small exhaust, reducing the calciner and kiln feed coal, good control of the temperature and cyclone kiln temperature, using a short flame burning anxious, waiting for materials soon. In normal production, there are fluctuations in the rotary kiln feed, but less volatile. But some problems when equipment or raw water in the rainy season is not easy to control, prone to raw material in the top of your library or library wall agglomeration, resulting in poor cutting, there will be greater volatility. In this case the operator is required to ground observation, ground adjustment, but also have a certain predictability. Conveying device according to some current changes to determine how much of the material. Pre-made response to treatment measures to reduce the yield, quality and equipment adversely affected.
