The main part of the furnace body ⑴Preheating section: The biggest feature of this section is that it does not directly contact the material. The main purpose is to dry and heat the carbonized material through heat exchange between the refractory bricks and the material, and the other is to assist the combustion chamber at the top of the regenerator to heat up. The combustion chamber is not connected with the air pipe, so no air is blown into it, and the temperature cannot be adjusted. The temperature changes with the temperature at the top of the regenerator, without adjustment. The specific change process is: In the blast heating section, the high-temperature flue gas from the lower part of the furnace body passes through the refractory bricks to exchange heat with the carbonized material and enters the regenerator for combustion, and the temperature of the combustion chamber decreases at this point. In the steam cooling section, the superheated steam heated by the regenerator carr…
