ABSTRACT:
The apparatus disclosed comprises conduits connecting the outlets of a plurality of heating zones of wood dryers to a common stack through which the emissions from all of the zones are discharged to the atmosphere. The common stack and the conduits between the common stack and the outlets of the heating zones of the dryer or dryers are insulated to maintain the temperature of the gases and vapors coming from each zone reasonably close to the temperature of the heating zone. This result is a reduction in the opacity of the emissions to ten percent or less.
