Abstract:
An air heating apparatus may comprise a housing with a path through an interior of the housing between openings in the housing. An isolating wall may divide the interior into primary and secondary chambers, and may have a transfer opening through which the path extends from the primary to secondary chambers. An air heating assembly may comprise an engine in the primary chamber, a heat generator in the primary chamber and connected to the engine, and a main heat exchanger in the secondary chamber and in fluid communication with the heat generator to transfer heat generated by the heat generator to air flowing along the path. The apparatus may include an air movement assembly configured to move air along the path and comprises a primary fan between the primary and secondary chambers to move air from the primary chamber to the secondary chamber.
