发明名称 COMBUSTION APPARATUS
摘要 PROBLEM TO BE SOLVED: To prevent a combustion failure during low combustion in a combustion apparatus with an increased turndown ratio.SOLUTION: A combustion apparatus includes: a fuel injection nozzle 1 disposed near the central axis of a burner, and a cylindrical combustion tube 3 provided to surround the fuel injection nozzle 1, and is configured to perform combustion by blowing combustion air supplied from a blower 10 to the combustion tube 3 toward a combustion unit on the tip side of the fuel injection nozzle and mixing fuel injected from the fuel injection nozzle 1 to a combustion air flow, and to switch a combustion state from low combustion to high combustion by changing a fuel amount supplied to the fuel injection nozzle 1. A flow path division member 2 is provided in the combustion tube to divide the inside thereof into a central air flow path 16 on the fuel injection nozzle side and a peripheral air flow path 17 on the peripheral side, and an air supply path for supplying the combustion air to the combustion tube 3 is separately provided with a first air flow path 4 for supplying the combustion air to the central air flow path 16 and a second air flow path 5 for supplying the combustion air to the peripheral air flow path 17.
