METHOD AND DEVICE FOR GENERATING SUPERHEATED STEAM Russian patent published in 2021 - IPC F22G5/16 

FIELD: thermal power engineering.

SUBSTANCE: proposed invention relates to thermal power engineering and can be used at thermal power plants during the operation of heating turbines for the utilization of secondary steam after the turbine. The technical result is achieved by a method and a device for generating superheated steam, containing a secondary steam pipeline connected to a steam turbine and an inlet tangential branch pipe of a cyclone, the upper branch pipe of which is connected to a receiving chamber of a steam jet ejector, the nozzle of which is connected to a waste steam collector, a diffuser with a low pressure damper connected to the ejected steam collector and through it - to the superheater, which is a battery consisting of an even number of pipe-in-pipe heat exchangers, the heat jackets of which are connected from above and below through shut-off valves to the collectors of hot and return flue gases, respectively, the upper ends of the pipes of the above-mentioned heat exchangers are also connected through the shut-off valves to the collector of ejected steam, the lower ends of these pipes through tees equipped with shut-off valves are connected to the collectors of the waste and superheated steam, and the latter is connected through a high-pressure damper equipped with a pipeline of superheated steam with a shut-off valve, with the consumer.

EFFECT: invention increases the ecological and economic efficiency of the method and device for generating superheated steam.
