A PRV or a pressure reducing valve (or pressure regulator) is a form of valve that stops the flow of a liquid or gas at a pre-determined pressure. This pressure reduction results in a direct waste of steam energy. However, by using a steam turbine, it is possible to reduce steam pressure while simultaneously generating electricity.  (Please see tutorial bellow)

CHP or combined heat and power is a method of generating electricity while simultaneously generating useful heat. It is a form of cogeneration. (Please see tutorial bellow)

In place of a PRV, a steam turbine will: 

  • Generate electricity “for free” since it was originally wasted
  • Reduce your firm’s operating costs while shrinking your carbon footprint
  • May qualify your company for energy efficiency credits

If your steam turbine PRV replacement solution is correctly configured, payback periods can range anywhere form 1 to 3 years. This of course will vary based on the specifics of your operation. 

Typically we can deliver our turbines within 4-6 months of receipt of a commercially and technically clear order. 

Our turbines are very efficient and range from about 34% efficiency for a single-state unit up to 70% efficiency for a multi-stage unit. 

We offer turbines as low as 5kW of power up to 3.2 MW of power for these applications.

How Does Steam Recovery Work?

PRV paralelling

Case study – PRV

  • Boiler Rating
  • 700 Psig Inlet to expander
  •  650 Psig Steam Flow – 20,000 lbm/hr
  • Process/Heat requirement – 70
  • Psig Power Generated – 600 kWe

      ********************************************************

  • @0.105kWeh x 8,000 hrs/year x 600kWe = $504,000.00/yr
  • Less than a 3-year payback

CHP oportunity

Case study – CHP

  • Boiler Rating – 600 Psig
  • Inlet to expander – 600 Psig @700 F
  • Steam Flow 40,000 lbs/hr
  • Process/Heat requirement – 160 Psig
  • Power Generated – 1.05 MWe
