Automatic control system and control method for circulating air temperature of annular sleeve kiln
The invention relates to an automatic control method for the circulating air temperature of an annular sleeve kiln. The automatic control method comprises the following steps that firstly, according to a parameter table, corresponding circulating air temperature reference values T are set by a system under different yields M automatically, and different heat consumption reference values H, upper and lower burner gas distribution ratios A and upper and lower burner combustion-supporting air ratios B are set under different heat value R intervals; then the detection value and the reference value of the circulating air temperature is tracked and compared by the system automatically, and the heat consumption parameter H is corrected; and the change of the temperature of a lower burner in unit time is tracked, and gas heat value detection data is corrected, so that the gas heat value data is close to a real value. According to the automatic control method for the circulating air temperature of the annular sleeve kiln, parameters can be quickly and accurately calculated when the heat value changes greatly, the flow of gas entering the kiln is accurately controlled in time, the temperature of circulating gas is controlled, the stability of lime quality is kept, the reasonable utilization of energy is achieved, and production energy consumption and waste gas emission are reduced.
本发明涉及一种环形套筒窑循环空气温度自动控制方法，首先根据参数表在不同产量M，系统自动设定对应的循环空气温度基准值T，以及在不同热值R区间下，设定不同的热耗基准值H、上下烧嘴燃气分配比A和上下烧嘴助燃空气配比B；然后系统自动跟踪对比循环空气温度的检测值与基准值，实施对热耗参数H进行修正；跟踪下烧嘴温度单位时间的变化，实施对燃气热值检测数据进行修正，使得燃气热值数据接近真实值。实现了热值大变化时的参数快速准确的计算，及时准确控制进入窑内的燃气流量，达到控制循环气体的温度，保持石灰质量的稳定，实现了能源的合理利用，降低了生产能耗和废气的排放。
