In the tank-type carbon calcining furnace, every four calcining tanks and the furnace walls with heating fire channels located on both sides of the tank body constitute a combustion chamber, and there are expansion joints and collecting flues between the combustion chambers. The furnace wall with the heating fire channel has 8-10 layers of fire channels, and the fire channels are connected to the preheating air channels. The calcining tank body is connected to the discharge tank, and the outer periphery of the discharge tank is provided with an interlayer cooling water jacket.

[0004] In order to solve the problems of insufficient utilization of waste heat, low calcination efficiency and quality, the existing technology uses excess volatiles for waste heat power generation.
