Abstract

A chimney cowl has a vertically- spaced series of five annular vanes (10) centred on a common vertical axis. The vanes are carried by three supports (11) equi-spaced around the inner peripheries of the vanes, the supports mounting co-axially with said vanes and between the uppermost vane and the vane immediately subjacent thereto a device (12) providing upper and lower aerofoils. The uppermost and lower most vanes are parallel and are of frusto-conical shape and the three intermediate vanes are parallel and are normal to the vertical axis of the vanes. The upper aerofoil (13) is a wall of conical shape parallel to the uppermost vane and the lower aerofoil (14) is a wall of inverted conical shape seating within and secured to the wall of the upper aerofoil. Means for clamping the cowl in position in a chimney outlet (9) is provided. <IMAGE>
