Abstract
A large scale field erected air cooled industrial steam condenser. A bottom bonnet runs along the bottom length of the heat exchanger bundle for delivering steam to the bottom end of the condenser tubes and for receiving condensate formed in those same tubes. The tops of the tubes are connected to a top bonnet. Uncondensed steam and non-condensables flow into the top bonnet from the condenser tubes. Each cell of the ACC is fed by steam distribution manifold suspended from and directly below the bundle support framework.
Claims11
An air cooled industrial steam condenser, comprising:
- a plurality of heat exchanger bundles, and each heat exchanger bundle having a longitudinal axis and a transverse axis perpendicular to its longitudinal axis,
- each heat exchanger bundle comprising a secondary condenser section, a primary condenser section and a top bonnet connected to and in fluid communication with a top end of each tube in said secondary condenser section and said primary condenser sections, a primary bottom bonnet connected to and in fluid communication with a bottom end of each tube in said primary condenser sections, an internal secondary chamber inside the bottom bonnet connected to and in fluid communication with a bottom end of each tube in said secondary condenser section, each said primary bottom bonnet having a single stem inlet;
- a steam distribution manifold arranged below said heat exchanger bundles and oriented along an axis that is perpendicular to a longitudinal axis of said heat exchanger bundles, said steam distribution manifold having at its top surface a plurality of connections adapted to connect to said primary bottom bonnet inlets.
