Siemens’ Enhanced Platform Design For Steam Turbines

Company’s EPD based on individual standardized modules; developments in three different design variants

Posted on June 3, 2014

Siemens Energy has shipped four industrial steam turbines of the company’s enhanced platform design (EPD).

One of the turbines will be used in a fertilizer factory in Indonesia's East Java province, delivering an electrical generating capacity of 12 MW. Two turbines, each with a rating of 61 MW, will generate electric power from biomass in Pakistan, while the fourth unit is destined for installation in Germany.

All four machines are based on the SST-600 series steam turbines with enhanced efficiency and represent developments in three different design variants, Siemens said. The turbines are each supplied to operate as a controlled extraction back-pressure turbine, controlled extraction condensing turbine, and condensing turbine.

The company said its EPD for industrial steam turbines offers the flexibility of various applications in performance classes ranging from 15 to 250 MW. Higher efficiency rates are achieved by utilizing the efficient blading system, an optimized steam path, more efficient extraction control elements and an advanced casing design.

Siemens said the EPD is based on individual standardized modules that can be assembled in rule-based combinations depending on the given area of application and steam parameters needed.
