WebThe turbine gland steam condenser is a heat exchanger that uses a partial flow of the condensate system through tubes to condense steam drawn from the steam turbine’s shaft seals. The condensed steam flows into the condensate receiver tank and the non-condensable gases are vented to the atmosphere. WebJul 22, 2010 · The gland condenser uses cooling water to condense this steam to water which is usually lost to sewer. A steam powered eductor draws a vacuum and expels the non-condensables that are drawn down with the steam to the gland condenser. WebSteam enters the condenser shell through the steam inlet connection usually located at the top of the condenser. It is distributed longitudinally over the tubes through the space designated as dome area. When the steam contacts the relatively cold tubes, it condenses. This condensing effect is a rapid change in state from a gas to a liquid. orion electronics co. ltd. russia
