Shell & Plate Heat Exchanger Fully Condenses Surface Condenser Outflow, Relieving Backpressure And Boosting Generating Capacity

In summer, power plants can lack the cooling capacity to condense adequately the LP steam outflow from the turbogenerator. This results in steam flashing from the condensate and applying backpressure back through the steam turbine outlet. This backpressure can significantly reduce turbogenerator output and degrade the overall thermal efficiency of the power plant.

A power plant installed Tranter Shell & Plate Heat Exchangers downstream of the surface condensers. The exchanger’s efficient plate technology with its small footprint fit on an existing deck. Not only was the basic footprint a consideration, but also the dead space necessary to pull the thermal element for service. For the same cooling service, the dead space is many times less for the shell & plate unit than a conventional shell & tube exchanger.

The increased turbulence of plate technology promotes higher heat transfer rates than with tubes, enabling the exchanger to make better use of lower grade cooling streams. Its reduced hold-up volume requires less pumping energy than do S&T exchangers.
