Abstract

A method and apparatus for accelerating solid particles entrained in a carrier gas so as to maximize the velocity of the particles at the output end of a duct is presented. This maximized or optimal acceleration is achieved by varying the cross section of the duct over at least the last 5 meters upstream from the opening thereof. Preferrably, the cross section of the duct should continuously increase i.e. diverge, towards the opening. This diverging cross section is preferrably in accordance with a nonlinear function of the length.
