PURPOSE: To get a high calorie and enable a portable unit to be provided by a method wherein raw material gas in which low class hydrocarbon fuel and gas including molecular oxygen are premixed to have a composition within a range of combustion is supplied to a monolithic type catalyst.
CONSTITUTION: A full volume of fuel and gas containing molecular oxygen having a volume required for a complete combustion of the fuel, for example, air are premixed to have a composition within a range of combustion, whereby an initial speed of passage through a catalyst layer is controlled to show a low value. As a fuel to be used, a low-class hydrocarbon such as a gaseous fuel, i.e. methane, propane, butane and natural gas or a liquid fuel such as methanol can be used. Ignition is carried by facilitating an ignition of mixed raw material gas containing fuel of a range of combustion and gas containing molecular oxygen by an electrical heater placed near the catalyst layer. With this ignition and combustion, the catalyst layer is heated, dilution gas is supplied to it to start up the catalyst combustion. Use of the monolithic catalyst enables a large amount of clean hot air to be attained.
