Abstract
The method of incinerating a combustible material (1) comprises, before custion, the following steps: dividing (2) the material into particles, incorporating (3) the divided material into an aqueous medium at a rate of not more than 35% by weight of solid relative to the liquid, foaming and pressurizing the suspension thereby obtained, by incorporating an oxidizer gas (10) and surface-active additives (9) in a mixer (8) of the suspension.
Claims2
A method of incinerating a combustible material (1), characterized in that it comprises before combustion (13) the continuous performance of the following steps:
- (a) dividing (2) the material into particles,
- (b) incorporating (3) the divided material into an aqueous medium at a maximum rate of 35% to 45% by weight of solid relative to liquid to form a suspension,
- (c) increasing the pressure of the suspension thereby obtained,
- (d) foaming the suspension under pressure, by incorporating an oxidizing gas (10) and surface-active additives (9) into said suspension in a mixer (8).
