ABSTRACT:
A hot fluid generating apparatus includes a combustion chamber, a regenerative combustion burner, a fluid passage formed along a wall structure of the combustion chamber, and a device for causing fluid to flow in the fluid passage. The combustion chamber has a flame radiation heat transfer only as a heat transfer portion. A portion of the wall structure opposite to the burner is utilized as a radiation heat transfer portion. A portion of exhaust gas from the burner is recirculated to the supply air to suppress generation of NOx. A portion of the wall structure close to the burner is formed to be a cone.
