So as not to have to provide continuously the high heat output needed briefly for short surges of steam, such as in steam irons or steam presses, the thermal capacity of a flow-type steam generator of porous sintered metal is utilised. The sintered metal block is heated electrically to a certain maximum heating temperature, for example, and when steam is needed, water is introduced into the flow-type steam generator, which vaporises on the hot grains of sintered metal, and is supplied to the consumer component via a steam discharge line. No high pressures result in the block of porous sintered metal, since the outlet of the flow-type steam generator is open when the water to be vaporised is introduced. Thus the vaporisation of the water supplied occurs at ambient pressure. In a preferred embodiment, a jet pump is integrated into the steam discharge line between the steam consumer and the flow-type steam generator; this sucks in steam that has not been used from the surroundings again. The steam-air mixture sucked in again is conditioned according to the desired thermal specifications of the steam needed, in a heat exchanger of porous sintered metal surrounding the mixing section. In continuous operation, a superheater follows the evaporator. <IMAGE>
