From The Fairbanks Daily News-Miner, Monday, December 6, 2010:
A new wood energy project in Tok has turned surrounding forests from a fire hazard into renewable fuel. The Tok School lit a new wood chip-fired boiler for the first time several weeks ago.The 5.5-million-BTU steam boiler produces the school’s heat, saving the school district thousands of dollars in heating fuel and saving forest managers untold costs fighting fires and eliminating waste wood. The school district plans to add a steam turbine generator to the system in May to produce 75 percent of its electricity.
“We’re the first school in the state to be heated entirely by wood,” said project manager and assistant superintendent Scott MacManus, who has been trying to spur wood energy in Tok for 10 years. “As far as I know, we’d be the first public school in the country to produce heat and power from biomass.”
At the school’s new biomass facility, trees and slash are fed into a Rotochopper grinder, processed into chips that resemble wood shavings, spit into a bin and carried by conveyor belt into the boiler, which is
17 feet tall, six feet wide and 12 feet long. Fuel comes from forest thinning projects, scraps and nearby sawmills. The forest around the school has yielded enough biomass for the first year, according to Alaska Division of Forestry spokeswoman Maggie Rogers. Project leaders hope the system will be used as a model of energy independence for other school districts, communities and utilities.
