VAMC TRI GEN PLANT 

“The biomass-fired Combined Heat and Power plant is designed to operate year-round, producing electricity at a capacity of 250 kW”

Project Description

The Veteran’s Administration, through funding provided by the American Recovery & Reinvestment Act, was engaging projects that increased energy independence, reduced fuel costs, helped the local economy and provided a source for renewable electricity.  The VAMC in White River Junction, Vermont provided steam to the campus using boilers fired on No. 2 fuel oil.  The VA chose WRJ as a location to retrofit the existing campus to run a tri-generation system of heating, cooling and electricity using biomass.

Project Features

Precision Energy Services was selected by the VA as part of a team contributor to supply and install a design-build biomass system.  The biomass-fired Combined Heat and Power plant is designed to operate year-round, producing electricity at a capacity of 250 kW.  The system provides steam and heat in the winter and operates a 500 ton absorption chiller for cooling in the summer.  The project incorporated all portions of the biomass boiler within an existing historical building on campus.  The project receives deliveries of hardwood log chips via walking floor trucks.  Once received, the chips pass over a scalping screen where any oversize material is ground by a wood hog and returned to the screen section.  The fuel is stored in a bottom reclaim silo and has a four day on-site storage capability.  Fuel receiving is located in a new warehouse over 300 feet from the boiler building.  From fuel receiving to ash handling, the biomass system is designed to operate with a high degree of automation using the operators on staff to run the additional systems.  PES was the design engineer, equipment provider and system integrator for the project.
