High -efficient low -nitrogen combustion cement raw of serial -type is decomposition device in advance

The utility model discloses a high -efficient low -nitrogen combustion cement raw of serial -type is decomposition device in advance, the device by main fire the reducing zone, assist fire zoneofoxidation, after -flame reinforce resolver, gas -solid two -phase equally divide export pipeline, once spurt throat, secondary spurt throat, cubic spurt throat, main wind entry, main coal entry, major ingredient entry, divide the wind entry, divide the coal entry and divide the material entry to constitute. In being applied to cement clinker calcination technology with the device, denitration efficiency reaches 35%-50%, and the denitration cost is showing and descends, is favorable to the environmental protection, guarantee producing, going into kiln raw material rate of decomposition under the condition of quality and reach 96%, adjust in a flexible way, the material homogenization is effectual, and the flow field is stable, and to raw materials, the fuel strong adaptability of difference, the thermal efficiency is high, and the heat rate reduces.
