To obtain a combustion heating furnace in which harmful combustion exhaust gas, e.g. carbon dioxide gas, is prevented from touching an object being heated, while saving on energy, by isolating a fuel combustion chamber from the object heating chamber.
The combustion heating furnace comprises a fuel combustion chamber 4 and an object heating chamber 2 wherein the combustion chamber 4 is disposed on the underside of the heating chamber 2 and a flue 6 is disposed on the upper side of the heating chamber 2. The combustion chamber 4 and the flue 6 are interconnected through a heat resistant pipe 7 exposed at least partially to the heating chamber 2 so that combustion exhaust gas generated in the combustion chamber 4 is exhausted through the heat resistant pipe to the flue 6 thus preventing the combustion exhaust gas from entering the heating chamber 2.
