3 Existing Boilers Average age is 46 years old 120k PPH average size 210k PPH total firm steam capacity
Issues: • • • • •
Replace Boiler 3 (1960) by 2020 Replace Boiler 2 (1966) by 2025 800 kW back pressure turbine Near cap of campus NOx emissions Located in flood plain
• 4 New Boilers • Relocate 800 kW back pressure turbine • 85k PPH average size • 255k PPH total firm steam capacity
Issues: • Located near Chilled Water Plant No. 2 • New gas utility • Rework existing steam and condensate piping • Reduced NOx burners to adhere to Title V permit requirements • Improve energy efficiency • Improve redundancy and reliability
• • • • •
6 MW high pressure gas turbine 2 MW steam turbine 800 kW back pressure turbine Produces 100k PPH steam Supplement with steam generator for remaining 150k PPH campus load
Issues: • New high pressure gas utility • Electrical interconnection to campus switchgear/substation • Improved energy efficiency • Significantly reduced NOx levels • Significantly reduced GHC emissions
