Abstract

768,799. Centrifugal fans. CLEAVERBROOKES CO. April 22, 1955 [July 21, 1954], No. 11671/55. Class 110 (1). [Also in Group XII] An uncased fan for providing air under pressure in a chamber comprises a fan wheel situated between a wall of the casing and a plate extending radially beyond the wheel to form a peripheral space about the wheel between the chamber wall and the plate. The fan supplies air to a burner 9, Fig. 3, in a boiler, the fan wheel 15, Figs. 2 and 3, being mounted on the shaft of the driving motor 17 which is supported by a bracket 18 on the outer door 14 of the boiler. The wheel 15 operates in the space between a portion 23 of the door 14 and a plate 32 spaced therefrom by spacers 33. Air is drawn in through a duct 25 and a central aperture 24 in the door portion 23. An inner door (not shown), with an aperture through which the burner 9 extends, abuts the door 14 when the latter is closed. An atomizing air pump 30 and a fuel pump 31 are driven by a belt 29. The wheel 15 may be open or partly or fully shrouded, and the blades 19 may be radial as shown or forwardly or backwardly curved. The plate 32 may be shaped so that the peripheral space around the wheel is of uniform extent, and it may be provided with vanes. Instead of being directly driven as shown, the fan may be driven through a belt or gearing.
