ABSTRACT:
The air flow in one zone of a gypsum wallboard dryer involves removal of the air from the wallboard drying section at one end of the elongate wallboard drying section, followed by directing a major portion of this air through fans to accelerate the air flow, next heating the air in an elongate plenum, through which the air passes, by directing high intensity flame angularly into the air flow from the periphery of the elongate section, thus creating agitation within the air flow to create uniformity of temperature therethroughout prior to directing the heated, thoroughly mixed air back into the wallboard drying section, at an end of the section opposite to the end from which it was originally removed.
