The condensing turbines take high pressure steam, expand it in turbine nozzles and blades, and exhaust it to a condenser at lower than atmospheric pressure. It is principally used when power must be generated with minimum steam consumption. The condensing turbine may also have bleed points (uncontrolled extractions) to satisfy steam demands at medium intermediate pressures.

Condensing Steam Turbine

This provision is applicable when the bleed (medium pressure) steam volume demand is low and pressure variations can be tolerated. These turbines are of bleed cum condensing type.

These type of turbines find application mainly for power generation where bleed steam is required for feed water heating (HP heater, LP heater and Deaerator requirement) and / or where bleed steam is utilized to meet small process demands.
