RECONSTRUCTION OF THE FRONT END GLAND OF THE INTERMEDIATE-PRESSURE CYLINDER OF THE K-300-240 TURBINE AT THE KONAKOVSKAYA GRES USING MATHEMATICAL MODELING

摘要

In order to raise the reliability of operation of the system of end glands of K-300-240 turbines at the Konakovo State Regional Power Plant (Konakovskaya GRES), the system for feeding steam to the end glands of high-pressure and intermediate-pressure cylinders has been updated. The updating included reconstruction of chimneys at the suggestion of the Komtek-Energoservis Co. and feeding of cooling steam to the zone of the third compartment of the front end gland of the intermediate-pressure cylinder. The measures taken increased the reliability of operation of the system of turbine glands, eliminated oil watering due to steaming, and reduced the temperature deformations of chimney gland yokes.
