Abstract
A hermetically sealed gas heater (110) includes a heater main body, an introduction hole (132) configured to introduce a fuel gas into the heater main body, a combustion chamber (136) configured to combust the fuel gas flowing from introduction hole, and a discharge section (138) into which an exhaust gas generated by combustion in the combustion chamber is guided. The heater main body includes a radiation surface (140) heated by the exhaust gas flowing through the discharge section and configured to transfer radiant heat to a heating target (156). An ejection port (142a) configured to partially or entirely eject the exhaust gas to the heating target is formed at the radiation surface.
