PURPOSE: A hot blast heater by a diffusion combustion tank is provided to repeatedly combust by convection current and to absorb the current heat and radiation heat with cold air in a combustion chamber. CONSTITUTION: A hot blast heater by a diffusion combustion tank comprises a first combustion chamber(1) having a furnace tank(12); a diffusion combustion tank(11) received on the furnace tank; a through hole(13) formed on the furnace tank; a connection pipe(116) inserted to the through hole of the furnace tank; a heating pipe connecting hole(14) mounted on an upper side of the furnace tank; a heating pipe(2) engaged with the heating pipe connecting hole; a body(21) passing through heat and flame; a wing(23) attached to the heating and radiating pipes; a second combustion chamber body(31); and a partition plate mounted in the body of the second combustion chamber. Thereby, the hot blast heater by the diffusion combustion tank repeatedly combusts by convection current. Moreover, the hot blast heater absorbs the current heat and radiation heat with cold air in the combustion chamber to discharge with hot blast.
