MECHANICAL DRIVE TURBINES

Skinner Power Systems manufactures nine (9) models of single-stage steam turbines with power output of 5 to 3000 horsepower.   Our turbines are generally in compliance with applicable API standards.   All horizontally-split models are available with sleeve bearings.  Certain models are also available with ball bearings.

The capabilities of our workhorse 2000 horsepower S-28 model and our popular 450 horsepower SB-18 ball bearing model are well known.  But, we also make a vertical version of the SB-18, the SBV-18.   The SBV-18 uses the same bearing sizes as the SB-18 with different angular contact for the orientation.  We use grease lubrication or optional oil-mist lubrication with lip type seals on the shaft because we believe plant operators would rather change the seals every few years than tolerate constant oil leakage.   There are various mounting options to meet your needs.  The power range of the SBV-18 is from 5 to 300 horsepower.  

The Skinner SK-25 turbine is an excellent choice of driver for high horsepower or low inlet pressure applications.  This 3000 HP plus turbine is ideal for those applications requiring larger power output.  But, because of the large inlet availability and nozzle ring design on the SK-25 model, even low pressure steam can be used to develop power requirements for your project, whether it is a pump or fan drive, or a steam turbine generator set.  It has many superior construction features:  velocity design with 2 wheels with easily replaceable blades, horizontal split construction for inspection and overhaul, sleeve type radial bearings, tilting pad thrust bearing, force feed lubrication which greatly increases service life by minimizing friction and wear, and electronic speed controls for safer, more efficient operation and communication to plant operating systems.

STEAM TURBINE GENERATOR SETS versus DIESEL GENERATOR  SETS

Steam turbine generator sets do not have the same operating characteristics as diesel engine sets.  While there are similarities, there are significant differences.  A diesel engine’s power output is simple; more fuel, more power.  Since engine designs have  features to alter operating characteristics, fuel usage is very predictable, and quite linear. A turbine, however, is designed to operate efficiently at one point, the design point, which is usually the highest power and/or highest steam flow.  The steam nozzles, the key to the turbine’s power, are fixed orifices; and, at conditions other than the design point, the turbine becomes less efficient.  This means less power per pound of steam.

Another difference between engine gen sets and turbine gen sets is the turbine gen set may have greater horsepower loss due to exhaust pressure loss, inlet losses in the governor valve operating at low end, in addition to losses in the driven equipment.  Therefore, the turbine may have to produce quite a bit of horsepower before any electricity production is possible. This may result in steam usage of 25% to 40% of top end flow just to make the first few kilowatts of power.  Engines don’t have these types of losses. 

Consequently, if low steam flows below the design point are likely, they need to be taken into account when designing your turbine gen set project and calculating cost savings.

COMBINED HEAT AND POWER: ENERGY SAVINGS AND TAX SAVINGS

These days there is a new buzz-word in our industry.   It’s “Combined Heat and Power” or “CHP” for short.  It can be defined as the simultaneous or sequential generation of useful heat and power from the same fuel source.   Thirty years ago we called it “Co-generation.”   Either way, it’s about getting the biggest bang for your buck!
