Abstract
A method and apparatus is disclosed for high intensity treatment of solid particles in a combustion chamber (10) by introducing the particles into the combustion chamber (10) as a plurality of streams (30, 32, 34, 36) wherein fuel is introduced to the combustion chamber within the area formed by the streams of particles and fuel is also introduced into said combustion chamber so that it surrounds the stream of particles, and by introducing oxidizing gas into the combustion chamber so that the oxidizing gas mixes with and combusts the fuel to produce a first high intensity flame located within the area formed by the particle streams and a second high intensity flame surrounding the particle streams.
Claims26
An apparatus for high intensity treatment of solid particles comprising:
- (a) a combustion chamber;
- (b) means for introducing said particles into said combustion chamber as a plurality of streams;
- (c) first means for introducing fuel to said combustion chamber within the area formed by said streams of particles;
- (d) second means for introducing fuel into said combustion chamber surrounding said streams of particles;
- and
- (e) means for introducing oxidizing gas into said combustion chamber so that said oxidizing gas mixes with and combusts said fuel to produce a first high intensity flame located within the space formed by said particle streams and a second high intensity flame surrounding said particle streams.
A method of treating solid particles comprising the steps of:
- (a) introducing said particles into a combustion chamber as a plurality of streams;
- (b) delivering a first fuel to said combustion chamber within the area formed by said streams of particles;
- (c) delivering a second fuel to said combustion chamber at points surrounding said stream of particles;
- (d) introducing oxidizing gas into said combustion chamber so that said oxidizing gas mixes with and combusts said first and second fuels to produce a high intensity flame located within the space formed by said particle streams and a second high intensity flame surrounding said particle streams.
