Blower augmentor for power oil and power gas burners
An oil burner is described in combination: (a) a blower comprising a scroll housing and a driven squirrel cage, the squirrel cage having an interior air space, and having blades disposed around space and constituting an air impeller; (b) the scroll housing having a tangential air outlet, and further comprising a spiral wall encircling the squirrel cage; (c) a stationary barrier wall mounted in the housing and extending into the interior air space of the squirrel cage. The barrier wall extends outward from and with respect to a central axial area of the squirrel cage to a location adjacent the blades; (d) the housing is wider than the squirrel cage in axial dimension, to provide an end space between the squirrel cage and the housing, in which end space air tends to recirculate in the housing; and (e) support and baffle means disposed in the end space between the housing and squirrel cage, for mounting the barrier wall and for redirecting in outward directions a portion of the circularly travelling recirculating air in the housing.
