Is better insulation achieved with smoke pipes buried underground or installed overhead?

The exhaust gas temperature at the outlet of the graphite furnace in a certain carbon factory is 600 degrees; the length of the pipe is 80 meters, and its inner diameter is approximately 1. 3 meters; the flue is to be insulated internally, using 125-weight lightweight clay bricks and 50-mm thick aluminum silicate panels. The pipeline is painted with asphalt paint on the outside. I consulted a technician from a furnace installation company, and was told that in order to achieve good insulation for such smoke pipes, they should be buried underground rather than left above ground Is this correct? Seek expert advice to resolve doubts
Such smoke pipes generally provide good insulation when buried underground.
Burial provides good insulation, as the soil temperature remains constant.
These days, refractory bricks are no longer needed for internal insulation; ceramic fiber modules serve as an excellent alternative to them. Ceramic fiber products have low thermal conductivity and excellent insulating properties. For more information, please contact 0531-81188218
