The existing boiler plant contained three (3) high pressure steam boilers. The original 1984 South Wing contained two (2) 400 HP boilers and the West Wing built in 1993 contained one (1) 250 HP boiler installed in the same plant. Prior to the recent addition of the West Wing 6th floor and the Ambulatory Care Building, K&L Group evaluated the capacity and determined that the existing three (3) boilers were sufficient for the new forthcoming building addition. However, the new proposed East Wing addition required additional plant capacity in order to operate. The new design included the replacement of the existing 250 HP boiler with a new 600 HP boiler. A major excavation and building addition was added in order to facilitate the expansion of the plant. In doing so, the plant now supported the new 100,000 SF, 5-story East Wing addition.

Our design included:

• A new 600 HP high pressure steam boiler and new blow-down tank
• New, larger main steam piping (high pressure) to existing main HPS header, as well as underground piping changes
• Two (2) new, larger boiler feed pumps
• New, enlarged flue gas breeching and tie new branch connection into the existing 48″ diameter horizontal breeching
• Modifications to the plant piping for connection to the new boiler; including fuel oil, natural gas, gas vents, relief valve discharge(s), drain and blow-down piping (above and below ground)
• Modifications to the control system to accommodate the new boiler
