The Efficiency of Increasing the Steam Parameters of High-capacity Cogeneration Turbines

摘要

The economic efficiency of increasing the parameters of the steam of high-capacity cogeneration steam turbines from 23.5 Mpa, 560/560 deg C to 29.4 Mpa, 600/600 deg C is considered. The possibility and advis- ability of constructing such turbines on the basis of the T-250/300-23.5 steam turbine with steam parameters of 23.5 Mpa, 540/540 deg C is shown. The expediency of returning to operating the latter turbine with steam param- eters of 23.5 Mpa, 560/565 deg C is also demonstrated.
