Condensing Turbine and Extraction/Bleed cum Condensing Turbine
Condensing turbines take high pressure steam, expand it in turbine nozzles and blades, and exhaust it to a condenser at lower than atmospheric pressure.
- Are principally used when power must be generated with minimum steam consumption
- May include bleed points (uncontrolled extractions) to satisfy steam demands at medium intermediate pressures
- Find application 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
