FOR WASTE HEAT RECOVERY AND ODOUR CONTROL

The Shell and Tube Condenser  is used to condense vapours by indirect contact. Vapours enters via the top vapour collecting hood and pass down the inside of the tubes were the condensate is collected in a coned bottom and continuously discharged.

Cooling water enters near the bottom of the shell, circulates around the outside of the tubes and discharges as hot water near the top of the shell. The required outgoing water temperature is maintained by regulating the input of cold water through an automatic control valve, operated by a temperature sensor and controller. Non-condensable vapours are removed from the cone bottom.

Because of the indirect contact between water and vapours, the hot water produced may be used directly or as a heating medium. If no use is available the hot water should pass to a cooling system for recycle.
