Kind Code:
A1
Abstract:
Provided is a boiler capable of appropriately heating a heat exchanger tube even in a situation where the temperature of a heating element is relatively low. This boiler comprises a heating element, a heat exchanger tube, a container with the heat exchanger tube inside, and a circulation path that can circulate gas with a higher specific heat than air and includes the interior of the container. The heating element is disposed in the gas introduction portion of the container, which is a portion of the circulation path. The gas flowing into the gas introduction portion from outside the container heats the heat exchanger tube using the heat obtained from the heating element, and flows out from the gas outlet portion of the container.
