The hospital's central boiler plant consisted of three large water-tube boilers that provided high pressure (100 psig) steam for heating, cooling (through steam-absorption chillers), humidification and process loads (sterilizers, kitchen). This project replaced one boiler and retrofitted the burners on the remaining two boilers to improve the plant's reliability and operating efficiency.

• Boiler B-3 was replaced with a new four-pass, 15,000 lb/hr, high efficiency watertube boiler
• The new burners on all three boilers have a high turndown ratio (10:1) and oxygen trim control to maximize combustion efficiency, minimize energy consumption and reduce carbon emissions
• All three new burners are the Low NOX type, sharply reducing nitrogen-oxide emissions
• The upgraded boiler plant has a new computerized burner management system and can be remotely monitored from the hospital's building automation system
• All three boilers have new automatic surface blowdown controls that reduce chemicals used for boiler water treatment (and corresponding energy losses) and reduce the amount of water used for boiler make-up
