ENHANCEMENT OF STEAM-TURBINE CONDENSER STEAM-JET EJECTOR
Eurasian Physical Technical Journal, 2021 A three-stage steam-jet ejector EPO-3-200 with a working steam flow rate of 850 t / h is installed at the Combined Heat and Power Plant-2 of the city of Almaty on heating turbines. In this paper, the replacement of the existing three-stage steam-jet ejector with a two-stage steam-jet ejector is proposed and substantiated. As a result of the replacement,
