The River Protection Project - Steam Plant Facility, Hanford Nuclear Reservation, Richland, WA
Wood Harbinger teamed with University Mechanical Contractors for this design/build Steam Utility Plant. We furnished the mechanical and electrical design of the plant, including: six 1,200 hp firetube boilers, stack economizers, package deaerator and feedwater pump set, 25,000 gallon condensate surge tank and transfer pump set, pressurized fuel oil system, blowdown heat recovery, water softeners, and chemical feed system. The package boilers were modified to include parallel-positioning combustion controls and a plant distributed control system (DCS).
The plant is housed in a 113 foot by 98 foot pre-engineered metal building. The boilers are arranged in two opposing rows with all the burners facing a central firing aisle. The firing aisle is wide enough to accommodate the boiler tube-pull clearance. A steel pipe rack structure, build over the firing aisle, is used to support the major plant piping systems. The building structure is used to support additional loads for the stack economizers and ancillary piping.
The plant DCS was connected to a facility-wide SCADA system to allow operators to remotely monitor and controls the plant.
