Abstract
A delivery warmer comprises a catalytic combustion heat generating device, a container accommodating cooked food, and a container casing accommodating the container. In the catalytic combustion heat generating device, a fuel tank stores liquefied fuel gas. A nozzle section gasifies and injects the liquefied fuel gas. A combustion section introduces gas mixture of the gasified fuel gas and air, and causes a catalytic reaction for burning the gas mixture. An igniter ignites the gas mixture and commences the catalytic reaction. Thus, heat generated from the catalytic combustion heat device is used to warm the container accommodated in the container casing. The cooked food is kept warm and tasty for a long time.
