School Administrative District 54 expects the wood-pellet-fueled boiler to significantly cut its heating costs in three schools with a combined 1,500 students, according to the Portland Press Herald article. The Hurst pellet boiler is in the basement of one high school, fed with an auger from a 42-ton silo by the football field. The system runs off a 3,500-gal. hot water tank, warmed by the wood pellets and circulated in a loop to every room in all three schools.
pellet project was paid for with a low-interest loan from the federal
government, under President Obama's stimulus package, said School
Administrative District 54 Superintendent Brent Colbry. The boiler will burn
600 tons of locally produced wood pellets.
