ELECTRIC STEAM-GENERATING EQUIPMENT Russian patent published in 2015 - IPC F22B1/28 

FIELD: electricity.

SUBSTANCE: invention suggests high-pressure boiler for steam-generating equipment comprised of an evaporation chamber, electric heater in good thermal contact with a wall of the evaporation chamber, water inlet in the evaporation chamber cover, which is made separately from the above wall, and a pump coupled to the water inlet and intended to supply water to the evaporation chamber through the water inlet. The device comprises thermoresistant sealing facility placed between sealing surfaces at the heated up wall and in cover of the evaporation chamber and, in essence, in parallel to direction whereat the cover is installed onto the evaporation chamber. In other versions the device comprises a nozzle protruding from the cover to the evaporation chamber and a pump coupled to the nozzle and intended for water supply through the nozzle to the evaporation chamber, the evaporation chamber wall comprises a ledge opposite the water inlet, the boiler is designed to ensure during its operating temperature gradient between the electric heater and heated up surface of the evaporation chamber equal to at least 60°C/mm.

EFFECT: suggested versions of the boiler may be installed to any steam-generating equipment.
