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…
