Tahuna Intermediate School (Wood Chip Blower)
HA Foote Haulage, a trucking and landscaping supplies company, supplies wood chips from 22 Bridgman Street, Dunedin to Tahuna Intermediate School in Dunedin. A truck with a 9 m³ wood chip capacity is used for delivery. Wood chips are blown into a fuel bunker using a wood chip blower system
Wood chips are sucked from the truck into the blower (on the trailer) via a locally supplied flexible plastic pipe (diameter 210 mm) and then blown into the wood chip bunker via a galvanised sheet mild steel pipe. This second pipe is made of galvanised sheet mild steel due to the fire risk associated with electrostatic
charging if this pipe were plastic.
