Experimental assessment of the condenser at off-design modes

Autor: Artem Vodeniktov, Natalia Chichirova, Valeriia Melnikova

Publikováno v: Case Studies in Thermal Engineering, Vol 28, Iss , Pp 101457- (2021)

The article presents the results of thermal tests of the condenser of the steam turbine PT-25-90 UTZ during off-design operation. An increase in the pressure in the condenser for the possibility of heating the district heating water is considered. Th
