Abstract

A steam generator having an enclosure containing a liquid to be evaporated. A rapid evaporation module inside the enclosure comprising at least one heating electrical heating resistance housed in a porous body immersed in the liquid or located near this porous body. The generator includes an electrical gate and a device for detecting the level of the liquid to change the liquid level in the enclosure in a direct proportion to the steam output which has to be furnished, so as to lower the level when the steam output must be reduced and vice versa, and an electrical energy metering circuit to adjust the electrical energy supplied to the heating resistance in a corresponding manner.
