Air-cooled vacuum steam condenser
This patent describes a steam powered system. It comprises: a turbine for converting steam energy into mechanical energy upon expansion of steam therein, a boiler for generating steam to be fed to the turbine, and a conduit arrangement coupling the boiler to the turbine and then recoupling the turbine exhaust to the boiler through steam condensing mechanisms. The condensing mechanisms including: a plurality of finned tubes through which the expanded exhaust steam flows and is condensed; a plurality of bundle from headers at the lower ends of the condensing tubes for receiving exhaust steam from the turbine; a plurality of bundle divided rear headers, one for each tube row in the bundle, at the higher ends of the condensing tubes for receiving non-condensible gases; and means in the rear and last headers to remove non-condensible gasses from the rear headers along their full length.
