Abstract
A combustion heater includes an inner tube having a supply passage for combustion gas in an inner portion, and an outer tube disposed to provide a separated combustion space in an outer periphery of the inner tube. A hole part for ejecting the combustion gas is formed on a tube wall of the inner tube and combustion gas is ejected with ejection characteristics such that circulating flow is formed on the periphery of a stagnation point. According to this combustion heater, a stable flame can be formed without increasing costs and the heating efficiency can be improved.
