A new type of calciner with high performance is developed based on the study of several typical cement calciners. The gas flow field of the calciner is optimized by adjusting its structure and combining the spouting intensity and the swirling intensity of gas. Raw meal and pulverized coal can be well distributed in the gas flow in the calciner for insuring the efficient heat exchange between gas phase and flow phase and offering better reaction conditions. The gas flow resistance of the calciner is very low and the volume availability of the calciner is much better than other calciners. The efficient calciner will be used as a good choice to adapt to various poor fuels in the cement industry in China and can be used to guide the improvement of other calciners with weaker performance.
