ABSTRACT:
A rotary heat wheel structure for a rotary heat exchanger in which a rotating wheel is provided with heat exchange material and rotates within a wheel housing to continuously cross an inlet path of low pressure cooler gas and an outlet path of high pressure hotter gasses for pre-heating the gas in the inlet path for utilizing the heat in the burned gasses before discharge to atmosphere. The wheel housing encloses the periphery of the wheel and is also provided with housing pillars defining an inlet path opening and an outlet path opening through which the rotary wheel rotates. Interior surfaces of the housing pillars are provided with radially extending grooves which co-act with opposite side faces of the rotary wheel to provide turbulence between the wheel side faces and the pillar surfaces so that leakage of gasses from the outlet path to the inlet path in the wheel housing is reduced.
