Abstract:

The energy-saving type vertical kiln is characterized by less investment, simple operation,short circle of construction, low energy consumption and so on, the more important point is that waste gas can be recovered and treated. Seven-layer kiln lining combination is used, which has a good thermal insulation performance. The cheap anthracite chip can be used as fuel. The production with hidden fire operation can control the standard coal consumption of each ton of lime within 145kg. The implementation of hidden fire operation can make the full utilization of the heat generated by fuel combustion and the limestone fed into the kiln can be fully preheated.
