ABSTRACT:
A heat treatment equipment having a heating chamber having a plurality of regenerative combustors provided with direct-fired burner having a built-in porous regenerator, for applying a heat treatment to an object in the heating chamber, wherein the substantial average surface pore diameter is not uniform for porous regenerators in a plurality of direct-fired burners or a plurality of regenerative combustors. By making contrivances in the shape of porous regenerators of the direct-fired burners or the regenerative heat exchangers arranged in an area where substances causing choking tend to easily adhere to make it difficult for such substances to adhere or prevent choking phenomenon from becoming apparent.
