ABSTRACT:
A method for forming a turbulent suspension from a pulverous material and reaction gas by causing the pulverous material to flow downwards as an annular flow into the reaction chamber and by directing the reaction gas downwards inside the annular flow of the pulverous material, in which the suspension is produced by bringing the reaction gas into a high-force rotary motion and by then causing it, throttled, to discharge into the reaction chamber so that in the reaction chamber it meets on its outside a substantially vertically downward annular flow of the pulverous material, this flow being formed by utilizing the kinetic energy of the falling pulverous material on a convergent conical glide surface. An apparatus for forming a turbulent suspension from a pulverous material and reaction gas, which apparatus is adapted to be directed centrally downwards into the reaction chamber and consists of a feed pipe for the pulverous material, means for dividing the pulverous material and of a turbulence chamber for reaction gas, in which the feed pipe for the pulverous material has the shape of a downwards convergent cone, and inside the feed pipe there is an axially mounted turbulence chamber at the upper section of which there is a turbulence generator, and the lower section of the turbulence chamber comprises a cylindrical stabilizing member with a diameter less than that of the turbulence chamber.
