ABSTRACT:
A system for reducing volatile organic compounds, particulates and carbon monoxide in exhaust from a wood products dryer is disclosed. The dryer exhaust is combined with waste wood or biomass fuel and partially combusted in a rotary gasifier, then fully combusted in a secondary combustion chamber. Hot flue gasses form the secondary combustion chamber are used to heat the conduits carrying the exhaust from the dryer, to heat oil, and to preheat air input to the dryer.
