A heated crucible apparatus (10) allows the adjustment of a thermal profile within a combustion chamber (12) surrounding the crucible (15) by introducing a sub-stoichiometric or a super-stoichiometric mixture of fuel and oxidant into the combustion chamber (12) and varying the oxidant flow for sub-stoichiometric or fuel flow for super-stoichiometric mixture downstream of the initial combustion to control the release of heat in defined areas within the combustion chamber (12). The apparatus includes an oxidant (54) and fuel (25) supply at the primary injection point (32) followed by secondary injection of the remaining oxidant supply at specific intervals to achieve the desired thermal profile. An oxidant pre-heating heat exchanger (51) and a cooling heat exchanger (49) for material exiting the crucible may be provided.

Un appareil pour creuset chauffé (10) permet d'établir un profil thermique déterminé à l'intérieur d'une chambre de combustion (12) entourant le creuset (15) par l'introduction d'un mélange infra-stoechiométrique ou supra-stoechiométrique de combustible et de comburant dans la chambre de combustion (12) et par variation du débit du comburant pour le mélange infra-stoechiométrique ou du débit de combustible pour le mélange supra-stoechiométrique en aval de la combustion initiale pour contrôler la libération de chaleur dans des endroits définis à l'intérieur de la chambre de combustion (12). L'appareil comprend une alimentation en comburant (54) et en combustible (25) au point d'injection primaire (32) suivie d'une injection secondaire du comburant restant à intervalles spécifiques pour obtenir le profil thermique voulu. Un échangeur de chaleur pour préchauffer le comburant (51) et un échangeur de chaleur de refroidissement (49) pour la matière sortant du creuset peuvent être fournis.
