ABSTRACT:
A semi-convective forced air system for heating glass sheets during a heating cycle comprises a heating chamber having a length and a width, at least one heating element located within the heating chamber, a conveyor having a length and a width, the conveyor extending lengthwise through the heating chamber, a compressed air source, a plurality of air manifolds positioned within the heating chamber and in fluid connection with the compressed air source, each of the air manifolds having a length, and each of the air manifolds being oriented parallel to the length of the conveyor, and a plurality of nozzles mounted on each air manifold and in fluid connection with the air manifold for mixing together and directing toward the conveyor a combination of compressed air and over air to convectively heat a sheet of glass on the conveyor, the plurality of nozzles on each air manifold being spaced along the length of the air manifold.
