The existing boilers and associated equipment were old and in poor condition. This project replaced the old equipment, increased capacity and redundancy and lowered energy and operating costs. The project has reduced natural gas costs by $400,000 per year and has significantly reduced water consumption.

• Three fire-tube boilers, sized at 700, 700 and 350 boiler horsepower
• High efficiency, high turndown (10 to 1), Low NOX burners with oxygen trim control and variable speed burner fans
• New automated controls, metering system, all tied to campus EMS
• New reverse osmosis water system for boiler make-up water significantly lowered the amount of boiler chemicals used and reduced the amount of boiler blowdown and associated energy losses
• New deaerator, feed water pumps, condensate receiver, transfer pumps
• New electrical service to boiler plant
• Automated surface blowdown control, based on TDS. Blowdown heat recovery system.
• Steam trap were repaired or replaced over the entire campus. Leaking valves and PRVs were also repaired or replaced to reduce steam system losses.
• Some of the old condensate receivers/pumps were not functioning properly and condensate was being sent to drain. This equipment was repaired or replaced and condensate was returned to the plant.
