PRODUCTION MATTERS Watching the loaded trucks line up for the mill’s two chip dump- ers, it’s clear that despite the slowdown in the forest industry, the power plant is getting the volume of wood fibre it needs right now to operate comfortably. All of the wood fibre is brought in by truck, regardless of whether it is sourced at a local mill, from the woods, or from the landfill. A 65-foot and an 85-foot chip dumper, both manufactured by Megatech Engineering of Sur- rey, British Columbia, unload regular chip trailers. Trailers with moving floors are emptied into an unloading bin that is equipped with conveyors. Once in the wood infeed system, the fibre is processed through metal detectors and a Grizzly hogger from Brunette Industries in New Westminster, British Columbia, a process that provides what Clarke calls “a homogeneous mix” of fairly equal amounts of bark, sawdust, and shavings that is debris free and the ideal size for the plant’s requirements. Once processed, the mix is moved to the main storage benches in the yard, where it is aged. When ready for the plant, the fibre is moved by a pair of Caterpillar D9 dozers and a Komatsu D275 dozer to the “reclaim pile” and a pair of Industrial Service Inc. reclaimers. A conveyor system that is equipped with another screen then transports the fibre to the plant. The wood fibre is gravity-fed into the boiler, which is a Stir- ling CCZ (controlled combustion zone furnace) two-drum model with a water-cooled vibrating grate stoker.
