Abstract (en)
The combustion heater (1) includes an inner tube (20) having a supply passage (21) for combustion gas (G) in an inner portion, and an outer tube (10) disposed to provide a separated combustion space (30) in an outer periphery of the inner tube. A hole part (24) for ejecting the combustion gas being formed on a tube wall of the inner tube and a radiation promoting surface (20B) is disposed on an outer periphery of the inner tube. This structure suppresses excess temperature increase in the inner tube and improves heating efficiency in the combustion heater.
