It has the characteristics of strong production capacity, convenient construction, high thermal efficiency, long operation cycle and simple operation. Lime kiln is also well known by users for its advanced structure, reliable operation and stable operation. The lime kiln production line is a mechanical automation production line composed of a number of auxiliary equipment. A variety of fuels can be used in the production process. The operating principle belongs to chemical reaction industrial batch production. It is currently the most widely used equipment in the building materials industry.

[0003] Due to the characteristics of its own process and equipment, the smoke in the lime kiln and the air released from the inner sleeve are directly discharged without being effectively utilized, which means there is a large waste of energy.
