The Research and Application of Calcination Technology for theVertical Shaft Furnace

The calcination technology for the vertical shaft furnace was developed and applied in plant successfully to adapt the change market. The new construction was designed by simulation optimizing; the special new brick for resisting sulfur corrosion was invented, and its capacity of resisting sulfur is three times than the common brick; the manual operation was replaced by automatic combustion control system, which make it come sure that the vertical shaft furnace is operated automatically. The residual heat utilization can achieve 1.2 ton steam per ton CPC or generate220-260kWh per ton CPC, which is 1.5 times than the average level in whole industry. The efficiency of desulfurizing is above 95%, and the efficiency of dedust is more than 85%. The comprehensive technology is widely applied, and proved that it is friendly to environment and highly automatic, and is the first choice for production quality, investment and operation.
