An improved air-cooled vacuum steam condenser in a steam turbine cycle comprising a turbine for generating mechanical power, a boiler for generating steam, a conduit arrangement coupling the boiler to the turbine and then another conduit arrangement coupling the turbine exhaust back to the boiler through steam condensing mechanism. The steam condensing mechanisms include a plurality of finned tubes through which the expanded exhaust steam may flow counter to its condensate and be condensed; a plurality of front headers at the lower ends of the condensing tubes for conveying the exhaust steam from the turbine and receiving the condensate from the finned tubes; a plurality of rear headers at the upper ends of the condensing tubes for receiving the non-condensible gasses; and means in the rear headers 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:
A mechanism to remove non-condensible gasses in a steam condenser comprising:
In a device for condensing steam and for removing the non-condensible gasses therefrom, an improved conduit arrangement defining a gas/vapor path inside a bundle extending from a lower header to an upper header with condensing tubes extending therebetween for steam as it moves from the lower header to the upper 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 upper header, the pipe having a length which spans the breadth of the upper header, the plurality of orifices located in the immediate vicinity of the tubes with its orifices positioned with respect thereto for the purpose of inducing the residue gasses leaving each steam condensing the tube to flow directly into the sparger for removal from the upper header and then subsequent discharge from the system.
