Extraction Back-pressure Turbines


Extraction back-pressure turbines are employed when two or more types of process steam at different pressures are required. Process steam at required pressures is supplied through extraction openings and turbine exhaust, while generating power in the process. Electric output is dependent on the demand for process steam. If required, multiple steam extractions at different temperatures and pressures for plant processes can be supplied through extraction openings.
