Calcination process for replacing pulverized coal with calorific value fly ash of cement kiln
The invention relates to a cement kiln, in particular to a calcining process for replacing pulverized coal with calorific value fly ash of the cement kiln. The calorific value fly ash enters an inlet of a conveying pipeline after being unloaded from a carrying machine tool, an outlet of the conveying pipeline is communicated with an inlet of a top plate of a calorific value fly ash storage bin, the conveying pipeline conveys the calorific value fly ash into the calorific value fly ash storage bin, and a rotor scale is installed below the calorific value fly ash storage bin. The calorific value fly ash enters the output pipeline after being dynamically metered by the rotor scale, the fan conveys the calorific value fly ash into the coal mill through the output pipeline, and the coal mill grinds the calorific value fly ash. The coal consumption cost and the production cost are reduced, energy conservation, consumption reduction and emission reduction are realized, carbon emission is reduced, and meanwhile, safe and stable operation of equipment can be ensured.
本发明涉及水泥窑，特别是一种水泥窑热值粉煤灰替代煤粉煅烧工艺。热值粉煤灰从运载机具卸料后进入输送管道的进口，所述输送管道的出口与热值粉煤灰储存仓的顶板的进口连通，所述输送管道将热值粉煤灰输送至热值粉煤灰储存仓内，所述热值粉煤灰储存仓的下方安装转子秤，热值粉煤灰由所述转子秤进行动态计量后进入输出管道，风机将热值粉煤灰通过输出管道输送至煤磨内，所述煤磨对热值粉煤灰研磨。本发明降低用煤成本，降低生产成本，实现节能降耗、减排，减少了碳排放，同时能保证设备安全稳定运行。
