Abstract:
1. An arrangement, comprising: a steam turbine; a condenser; and a regenerative deheater, wherein the regenerative heater is arranged in a steam flow between the steam turbine and the condenser, wherein the regenerative heater cools down a steam exiting the steam turbine before entering the condenser, and wherein the regenerative heater heats up a feed-water stream, and wherein a bypass is arranged in parallel to the regenerative deheater so that a portion of the feed-water stream can bypass a heat exchanger of the regenerative deheater and whereby an energy exchange between the portion of the feed-water stream and the steam exiting the steam turbine does not occur, wherein a valve is arranged at an intersection between the bypass line and the feed-water stream entering the regenerative deheater, and wherein the valve separates the feed water into a first proportion of the feed-water stream entering the regenerative deheater and a second proportion of the feed-water stream bypassing the regenerative deheater.
