Brightwater hog fuel feed system

The Brightwater Hog Feed System was initially designed for Blue Mountain Lumber sawmill in Southland. The sawmill generates significant quantities of green sawdust, wood shavings, and lumber off-cuts which is utilised for a 10MWth steam and electricity co-generation plant.

The site requirement was for a system capable of handling the total range of wood residues and converting them into boiler fuel by passing them through a size-reducing hogger. It was also a requirement to be able to feed these residues into the hogger as either individual streams or as a mixture of different residue types.

Brightwater Engineers designed their Hog Feed unit to handle all material types and to provide a fully automated reception and discharge bunker mechanism.
