TURBINE SUPERHEATED STEAM GENERATING UNIT

摘要

FIELD: power industry.SUBSTANCE: invention is intended for steam generation for an electrical generator turbine and includes a superheater that receives steam from a steam generator and superheats it. Then, superheated steam leaving the superheater is passed either fully or partially through a heat exchanger to provide supply of some amount of heat energy of superheated steam to a water flow. This reduces the superheated steam temperature to the temperature acceptable for the turbine. The water heated in the heat exchanger can be thecondensed water that has already passed through the turbine and can be supplied to the steam generator where it is converted again to steam.EFFECT: improving efficiency of heat used in the unit.4 cl, 4 dwg
