根据热源换热方式或臭气处理方式不同，采用不同工艺系统：窑头热风间接烘干，臭气自循环；窑头热风直接烘干，臭气入冷却机进行焚烧；窑头热风直接烘干，臭气入除臭塔净化外排；热风炉热风直接烘干，物料无臭气产生。

There are great differences in bulk density, moisture content and compressibility among various alternative fuels. This easily leads to equipment blockage and material interruption, or severe fluctuation of feeding capacity, which further causes unstable consumption of calcining pulverized coal and results in poor thermal condition stability of the kiln system.
Therefore, this equipment is mainly used for accurate metering and stable feeding of alternative fuels before they are fed into the prec

由于生活垃圾及部分替代燃料中含有难燃的杂质，对后端如水泥窑分解炉接收造成较大影响，对节煤效果及系统稳定性都有严重不利影响，通过滚筒筛可实现杂质筛除，提高产品质量。

此配料系统能实现替代燃料的前端计量，根据所需的热值，对于多种替代燃料进行配比，然后分别给每种物料对应的配料秤设定产量，通过铲车或抓斗进料，配料系统根据设定的产量实时进行反馈调节，多种物料在经过配料秤系统计量后混合进入分解炉，实现多种物料的定量给料；可在替代燃料进入窑炉之前，作为称重计量装置进行使用，以控制和调节入炉给料量。

The stepped pre-combustion furnace is an online combustion technology deployed at the kiln tail. Alternative fuels feature complex combustion characteristics, large particle sizes and high moisture content. Direct feeding of such fuels is prone to causing substantial fluctuations in the clinker calcination conditions.
The pre-combustion furnace enables the online drying, pyrolysis and combustion of alternative fuels and expands material adaptability. It not only mitigates the impact of alternati
