Abstract:
A condensation system for the condensation of turbine exhaust steam, which is directed through one or more turbine exhaust-steam nozzles to a condenser installation, said condensation system comprising:a condenser installation;a cooling installation for condenser cooling media, the condenser installation having a surface condenser and a direct-contact condenser, both having respective condensing spaces;said cooling installation further having two separate cooling-media circuits, wherein the cooling media of the surface condenser and the direct-contact condenser passes through the cooling-media circuits separately;the surface condenser and the direct-contact condenser being arranged in a common condenser housing, or the surface condenser and the direct-contact condenser each being arranged in a separate condenser housing;flow guide baffles being arranged in the condenser space of the direct-contact condenser, such that new exhaust steam flowing in directly from the turbine exhaust-steam nozzles is passed over a hot well and a cushion is formed above the hot well by said new exhaust steam and whereby a clear path is provided for a part of the new exhaust steam to flow from the turbine exhaust-steam nozzles to the hot well and on to the condensing space of the direct-contact condenser; andthe steam flow runs counter or in crossflow to the condensate flow of the direct-contact condenser.
