ABSTRACT:
A fluid flow driven apparatus, specifically a gas-powered turbine, which is especially designed to operate on particle laden fluid is disclosed herein along with its method of operation. This apparatus includes a main drive shaft disposed within its own compartment and a plurality of rotor blades fixedly connected to the shaft at axially spaced locations along its length. The apparatus also includes means for directing a continuous fluid stream, laden with particles, into the compartment, and means for causing the fluid stream in the compartment to move axially therethrough along a helical path around the shaft in order to engage the rotor blades in a way which causes the shaft to rotate about its own axis. In addition, the apparatus includes a particle redistribution arrangement acting on the particle laden fluid stream at a location upstream of the rotor blades in a way which acts on the particles for causing the latter to impinge the rotors, especially the most upstream of the rotors, in a more favorable manner than would be the case without the particle redistribution arrangement.
