Rotary kiln internal temperature gradient control

Article source：

Rotary kiln temperature gradient is mainly the quantity, air flow, the combustion temperature is determined by three factors, to minimize the number of adjustments and adjustment range, not frequent adjustment. One kind of Rotary kiln temperature gradient optimization control method, according to the Rotary kiln temperature change and its rate of change to achieve closed-loop control of the Rotary kiln negative, according to the negative pressure and the load to achieve closed-loop control of the air flow.Can effectively solve the Rotary kiln temperature distribution caused by the irrational product quality problems.Fuel and unreasonable because the Rotary kiln temperature gradient caused by incomplete combustion problems, to reduce fuel consumption, stable product quality purposes.
