Colby College Central Heating Plant Expansion
Achieving campus-wide carbon neutrality.
This 12,700-square-foot, four-level expansion of Colby College’s Central Heating Plant houses new Chiptec biomass equipment and apparatus. The project features two 400-hp Johnston gasifier/boiler packages, each configured to produce 13,000 lbs/hr of high-pressure steam and 13.4 MMBTUs, and a fuel storage and delivery system capable of holding 72 hours worth of fuel at maximum firing rate. Work included site preparations, including the relocation of existing steam, sewer, water and communications lines.
The gasification system is designed to utilize clean woodchips with moisture content of up to 45% and help the College achieve campus-wide carbon neutrality.
