Title:
AIR-COOLED STEAM CONDENSER WITH IMPROVED SECOND STAGE CONDENSER
Document Type and Number:
WIPO Patent Application WO/2023/019010
Kind Code:
A3
Abstract:
Large scale field erected air cooled industrial steam condenser having heat exchanger panels with primary and secondary condenser sections, in which the secondary condenser section comprises 10% or less of the total heat exchanger, and in which the tubes of the primary condenser sections have narrowed outlet orifices having an area that is 50% or less than the cross-sectional area of a corresponding tube. The invention permits the reduction of secondary condenser tubes while reducing the outlet header pressure sufficiently to minimize backflow, sweep non-condensables and prevent the formation of dead zones.
