The brown gas heating furnace includes a hollow base, having burner mounting holes formed in a top wall of the base, and a door mounted at a front side of the base. The burners are centrally mounted in the burner mounting holes of the base, with branch ducts connecting each of the burners to a Brown gas supply duct. A heating section consisting of firebricks stacked together in a staggered fashion on the top wall of the base encloses the burner mounting holes, with a furnace section seated on the base and having a combustion chamber surrounding the heating section. The furnace section also has venting holes adapted to vent the combustion chamber to the atmosphere. The furnace section may include stacked blocks made of mineral stone, biotite, germanium, or jade, or may use hollow mineral stones. | |
