Abstract

The inducer has a central tube (1) which fits onto the end of the flue pipe. The central tube connects with two cones (17) separated by four fins (16) perpendicular to one another. The inverted cones are fitted with support plates (4) on the underside and a top cone (13). The cross draught causes a depression at the centre of the cone which draws the gases out from the central pipe. The inducer may be placed at an angle to the pipe for special applications.
