How Does Steam Recovery Work?

 

CHP Opportunity

steam recovery diagram 1

Case Study – CHP

• Boiler Rating – 600 Psig
• Inlet to expander –600 Psig@ 700 F
• Steam Flow – 40,000 lbm/hr
• Process/Heat requirement – 160 Psig
• Power Generated – 1.05 MWe
********************************************************
• @0./kWeh x 7000 hrs/year x 1050kWe=$ 00.00/yr
• Less than a year payback.

PRV Paralleling

Case Study – PVR

• Boiler Rating
• 700 Psig Inlet to expander
• 650 Psig Steam Flow – 20,000 lbm/hr
• Process/Heat requirement – 70
• Psig Power Generated – 600 kWe
********************************************************
• @0.105/kWeh x 8000 hrs/year x 600kWe=$ 504,000.00/yr
• Less than a 3-year payback.
