- 22 - An improved apparatus and method for efficiently processing material, e.g. incinerating waste material, particularly dewatered waste water sludge, in a multiple hearth furnace by injecting high velocity jets of oxygen into the heating or drying zone of the furnace to augment turbulent gas-phase mixing, to aid in the burnout of carbon monoxide and hydrocarbons in the gas phase to achieve lower emissions, to increase convection over the drying sludge to increase its drying rate, and to ignite the drying sludge to further increase its drying rate. The apparatus and method provides an increase in sludge throughput and a reduction in carbon monoxide, nitrogen oxides and hydrocarbon emissions.

Appareil et méthode améliorés pour la transformation efficace de substances, p. ex., l'incinération de déchets, en particulier de boues d'eaux usées essorées, dans un four à étages par injection de jets à grande vitesse d'oxygène dans la zone de chauffage ou de séchage du four afin d'augmenter le mélange par turbulence de la phase gazeuse, de favoriser l'épuisement du gaz carbonique et des hydrocarbures dans la phase gazeuse pour réduire les émissions, d'accroître la convection sur les boues en train de sécher afin d'accélérer leur séchage et de les enflammer pour qu'elles sèchent encore plus vite. L'appareil et la méthode contribuent à accélérer le débit des boues et à réduire les émissions de gaz carbonique, d'oxydes nitreux et d'hydrocarbures.
