Extraction condensing steam turbine The extraction condensing turbines are used when a constant pressure steam flow has to be extracted for process purposes. The constructional characteristics of these turbines are very similar to condensing turbines from the second admission valve chest it is possible to inject low pressure steam, available in the plant to supply the power required by the plant. These turbines are typically used for co-generation where the turbine meets both the power and steam demand of the process plant. In these type of turbines the power generated can be maintained more or less at a steady level despite variation in process steam demands. In some cases it may be necessary to have both bleed and controlled extraction steams from the condensing turbine. These turbines are of bleed cum extraction condensing type.
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 e. 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.
Proven reliability and high efficiency makes Kessels multi-stage steam turbines vital partners with the power and process industries. High fuel and energy conversion costs demand that steam turbine efficiency be as much a consideration as reliability. Kessels industrial multi-stage steam turbine line helps you meet a variety of energy requirements in industrial environments. These turbines operate at speeds up to 12,000 RPM, with steam inlet conditions up to 105 bar at 560oC, and exhaust conditions up to 12 bar.
