PROCESS AND APPARATUS FOR THE EROSION-CORROSION PROTECTION OF STEAM DUCTS FROM THE HIGH PRESSURE STAGE OF A TURBINE PROCESS AND FOR THE EROSION

摘要

A method and apparatus for preventing erosion and / or corrosion of a steam pipe at a high pressure end of a saturated steam turbine of a power generation and / or steam generation facility in a low pressure stage of a power generation and / or steam generating facility and a heater of a heat exchanger. Most of the water retained in the stage's wet steam outlet and offtake is separated by a centrifugal device. The first portion of steam partially dried by the centrifugal apparatus is superheated or finally dried and then fed to the low-pressure portion of the turbine and the remainder of the partially dried steam to the heater. The first part and the remaining part of the steam are dried together by a centrifugal device and then the remaining part is finally dried by a centrifugal device.
