Influence of reheat pressure on reheat cycle economy [PDF]
E3S Web of Conferences, 2021 After steam expands to a certain intermediate pressure in steam turbine, it is led out of steam turbine and sent to reheater of boiler. The steam is heated to the initial temperature by constant pressure in the reheater.
