Process for preheating condensate in a feed water tank of a steam power plant

摘要

A condensate warm-up device in a feed-water vessel (2) of a power station operates by means of steam removal (22) from a turbine (10,11) with a steam line (31) leading into the lower condensate space (30) of the feed-water vessel (2) and in whose flow is arranged a controlled adjustment device (25). The adjustment or setting device (25) has a controlled steam branch line (33) which discharges into the steam space (32) over the condensate space (30) of the feed-water vessel (2). The adjustment or setting device (25) is specifically a three-way valve. With a feed-water vessel (2) arranged with a degasifier (34), the controlled steam-branch line (40) is arranged into the steam space (32) up-stream of a further steam-branch line (41) into the degasifier (34).
