Electric heating cement clinker firing system and method
The invention provides an electric heating cement clinker sintering system and method. The electric heating cement clinker sintering system comprises an electric heating circulating fluidized bed decomposing furnace, a raw material preheater, an electric heating rotary kiln and a clinker cooling device, a discharging port of the raw material preheater is connected with a feeding port of the electric heating circulating fluidized bed decomposing furnace, a discharging port of the electric heating circulating fluidized bed decomposing furnace is connected with a feeding port of the electric heating rotary kiln, and a discharging port of the electric heating rotary kiln is connected with a feeding port of the clinker cooling device. According to the electric heating cement clinker sintering system and method, the electric heating circulating fluidized bed decomposing furnace, the raw material preheater, the electric heating rotary kiln and the clinker cooling device are used in cooperation, the cement clinker sintering process can be conducted in an electric heating mode in the whole process, fossil fuel is saved, NOx gas is not generated, a denitration system does not need to be arranged, and the cost is reduced. And meanwhile, the concentration of carbon dioxide gas generated in the cement clinker production process can be improved, and a subsequent carbon dioxide recovery system can be matched, so that carbon emission is effectively reduced.
本发明提供了一种电加热水泥熟料烧成系统及方法，包括电加热循环流化床分解炉、生料预热器、电加热回转窑以及熟料冷却装置；生料预热器的出料口连接电加热循环流化床分解炉的进料口，电加热循环流化床分解炉的出料口连接电加热回转窑的进料口，电加热回转窑的出料口连接熟料冷却装置进料口。本发明一种电加热水泥熟料烧成系统及方法，配合使用电加热循环流化床分解炉、生料预热器、电加热回转窑以及熟料冷却装置，可以实现全程使用电加热的方式进行水泥熟料烧成过程，节省化石燃料的使用，不产生NOx气体，无需设置脱硝系统，同时可以提高水泥熟料生产过程中产生的二氧化碳气体浓度，有利于配合后续二氧化碳回收系统，从而有效降低碳排放。
