Steam Surface Condensers & Bypass Condensers

Steam Surface Condensers & Bypass Condensers

A steam surface condenser is a critical component of a power plant. The generating capacity of a power plant is dependent on the performance of the steam surface condenser. Maarky condensers are designed to provide the lowest backpressure which, in turn, maximizes the output from the power plant.

Steam surface condensers are offered for power plants ranging in output from 10 MW to 1000 MW and in the configurations of Cylindrical, Inverted “U”, or Rectangular, Axial or Down Exhaust, Single or Multiple-Pressure, Single or Multiple-Shell, Divided or Non-Divided Waterbox, One Pass or Multi-Pass.

In an industrial or waste to energy plant, upon turbine trip, the high pressure steam from the steam generator is the attemperated in a pressure reducing desuperheating [PRD] valve and then condensed in the main condenser.

In certain instances, the steam from the PRD valve is condensed in a seperate heat exchanger often called the bypass condenser. Bypass condensers can be designed for a wide range of operating scenarios such as high pressure, low pressure, condensing only, condensing and subcooling, horizontal, vertical, constant pressure or constant level.
