An improved air-cooled vacuum steam condenser in a steam turbine cycle comprising a steam powered system comprising 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 include a plurality of finned tubes through which the expanded exhaust steam flows and is condensed; a plurality of bundle front headers at the input ends of the condensing tubes for receiving exhaust steam from the turbine; a plurality of bundle rear headers at the output ends of the condensing tubes for receiving condensate and non-condensible gasses; a plurality of vertically oriented water leg pipes, one for each bundle rear header of each bundle, coupling each rear header with a water leg manifold; a hydraulic balance device in the condensate drain system coupling the water leg manifold and a condensate storage tank, the hydraulic balance device providing the means to maintain a predetermined hydraulic pressure therein for thereby sustaining the heights of the condensate in the water leg pipes within predetermined limits for fluid sealing purposes; and means to remove non-condensible gasses from the rear headers.
A steam powered system comprising 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:
For use in a steam condenser, a condensing and draining mechanism comprising:
For use in a stream condenser, mechanism to remove non-condensible gasses comprising:
In a device for condensing steam and for removing the non-condensible gasses therefrom, an arrangement of conduits defining a gas vapor path inside a bundle extending from a front header to a rear header with condensing tubes extending therebetween for the stream as it moves from the front header to the rear and last header of the bundle where the non-condensible gasses terminate and collect as residue, the arrangement also including a suction sparger pipe having a plurality of orifices located inside the rear header, the suction sparger pipe being of a length which spans the breadth of the rear header with its plurality of orifices located in the immediate vicinity of the tubes and positioned with respect thereto for the purpose of inducing the residue gasses leaving each stream condensing tube to flow directly into the sparger for removal from the rear header and then subsequent discharge from the device.
