Profile:
Dump Condensers are used to recover large amounts of steam that may otherwise be vented to the atmosphere. During fluctuating steam loads, turbine trip off, turbine start-up, or bypass, the excess steam that would ordinarily be vented can be diverted to a dump condenser. Dump Condensers may also be used for process plants when upset demand conditions occur.

A dump condenser is required when the steam consumption needs to be drastically reduced in a very short period of time and when the boiler cannot follow this variation.

The design and construction of bypass condensers is similar to that of steam surface condensers and feedwater heaters.  The circulating water from the cooling tower flowing through the tubeside imparts the condenser characteristics, while the condensation and subcooling of the condensate on the shellside impose the feedwater heater characteristics.

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. Performance at off design conditions can impact the hardware design and therefore must be carefully considered prior to finalizing the mechanical design. Our copmpany bypass condensers are designed to offer reliable performance at all specified operating scenarios
