Rotary kiln preheater rising flue crust, blockage is often appear in the production of new dry process cement kiln. Crust, lime rotary kiln preheater rise of flue ventilation area is smaller. Serious when actual rising smoke ventilation area is only about a quarter of the normal situation.No deployment of kiln preheater rise of the flue gas control gate three duct airflow, preheater resistance loss increased significantly, poor ventilation, the stove kiln hair heat capacity is restrained, kiln head firing with a sharp drop in temperature above 200 degrees, can not meet the clinker calcining demand, severe run phenomenon of raw lime rotary kiln stove, even can extinguish the flame, the combustion of pulverized coal is not completely will add up the flue reducing atmosphere, accelerate the speed of crust.Therefore, rising flue crust blocking leads to kiln system disorder, the control parameters are difficult to adjust the control. So we should know something about it.

Our experts will teach you the way of dealing with rotary kiln temperature change strategy, which is as follows: sintering temperature from the normal to the development of low temperature and heat color fading, shadows move, should be timely and coal.When material gains from few, shorten flame, burning with the back of the change from light to dark, should increase coal as early as possible, with the increase of pulverized coal, primary air should also increase, to ensure the coal mix, wind burn quickly and completely. When the flame slightly short and powerful, the firing heat color than the normal dust is bigger, the clinker cooler is green gray, after the break open holes.

If the temperature stability, continue to develop in the low temperature, should be a little early local train, appropriate down exhaust, keep the same temperature, flame concentration. Otherwise, lower temperature continues to fall, heat color change from pink to red, burning out the rising number of clinker powder, the...
