Controlled combustion of wood wastes
Describes how an installation, supplied by Energy Products of Idaho (EPI), utilizes on-site wood wastes as fuel, saving a wood manufacturing plant $1.5 million annually in natural gas costs. The EPI system includes a fluidized bed chamber, a waste heat boiler, 2 fuel storage bins, a multiclone ash removal system and a network of ducting to deliver gases to and from 3 veneer dryers. It provides energy in both steam and hot gases, and at full capacity, can generate 100 million Btus per hour. The single, wood-fired unit has replaced one gasfired boiler, 3 gas-fired dryers, and 3 wood-fired boilers which supplied the plant's steam and hot gases. Presents a flow diagram of the fluidized bed combustion and energy system; and a graph showing wood energy values at varied moisture contents based upon natural gas at $5.7/mm Btus. The continuing development and refinement of fluidized bed technology, has led EPI to expand into the area of biomass gasification.
