Pour a lining? ? ? It’s already passed the smoke extractor, so the temperature shouldn’t be high, right?

Pour the lining. The temperature in the pyrolysis furnace exceeds 1,000 degrees, resulting in high residual heat.

Weren’t a lot absorbed by the convection module? ? ?

It has a lining, and the flue gas temperature at the flue is below 150 degrees. Some can go below 100 degrees.

Yes, it is prefabricated and cast in the factory. It’s not insulation.
