ABSTRACT:
A multi-stage axial flow turbine and blast furnace compressor blower comprises a blower having a degree of reaction of 100% and which includes a rotatable shaft having a plurality of rings with blades defining moving blade rows arranged in spaced location with a plurality of guide blade rows. The construction includes a plurality of stages between an iniaial and a final stage which include a moving ring with two relative moving blades and a single guide blade row. The initial and final stages are arranged so that the stages include either an initial single moving blade row and a final stage consisting of a single guide blade row and a single moving blade row or the initial stage comprises a single guide blade row and a moving ring with two rows of blades and the final stage comprises a single guide blade row. The construction makes it possible to foreshorten the shaft by providing one row of the guide blade blades to take up the pressure of two rows of the moving blades at 100% reaction between said initial stage and said final stage.
