PROBLEM TO BE SOLVED: To provide a combustion device easy to maintain with a simple structure, which hardly generates a harmful gas such as carbon monoxide or nitrogen oxide or smoke and soot. SOLUTION: This combustion device 1 comprises an oil injection nozzle 3 for injecting fuel oil 4 of ordinary temperature into a combustion furnace 2 having a cylindrical shape; a steam injection nozzle 6 for injecting superheated steam 5 into a mixing chamber 17a that is an area to which the fuel oil 4 is injected from the nozzle 3; a heated passage 7 that is a steam generation means generating the superheated steam 5; and a blower 8 that is a blowing means supplying air into the combustion furnace 2. The fuel oil 4 in an oil tank is supplied to the nozzle 3 via an oil feed pipe 10 by operating an oil pump P1, and water in a water tank is supplied to the heated passage 7 via a water feed pipe 14 by operating a water pump.
