Arrangement with a steam turbine and a condenser

摘要

An arrangement including at least one steam turbine and one condenser is provided. Further, a method to operate such an arrangement is provided. A regenerative deheater is arranged in the steam flow between the steam turbine and the condenser, by which the steam, superheated exhaust steam, exiting the steam turbine is cooled down before entering the condenser and by which a feed-water stream is heated up.

主权项

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.
