Patent ID: 8662482

Claim:
A method for condensing steam using an air cooled condenser, comprising: flowing a cooling air flow through a tubular shell having an open upper end and an open lower end to create a natural draught for cooling air flow, wherein the cooling air flow enters via the lower end and exits via the upper end; passing the cooling air flow over a ring of cooling panel pairs disposed generally vertically with the panels in each pair at an angle to each other and disposed at the lower end of the shell, with each of the panels comprising single row tube bundles with a primary condenser region and a secondary condenser region, and adapted for the cooling air flow to travel therethrough to condense steam in the panels; flowing steam through a duct disposed on the ground level of the shell to supply steam to the tube bundles; controlling the cooling air flow via a controlling device that adapts to different operating conditions; and controlling the local rate of evacuated mixture of non-condensables and attached steam.
