... other heat-treating processes applied in sludge incineration are the flash drying incineration system and the fluidized bed reactor ... A fluidized bed reactor uses a sand bed which is kept in fluid condition by an upflow of air, as a heat reservoir to promote uniform combustion of sludge solids. The bed is preheated to approximately 122 °F by using fuel oil or gas. When sludge cake is introduced, rapid combustion occurs maintaining an operating temperature of about 1500 °F. 1, record 1, English, - fluidized%20bed%20reactor

[Le] principe du four à lit fluidisé [...] consiste à introduire les boues dans un lit de matériau auxiliaire, généralement du sable, porté à une température de 700 à 800 degrés C et tenu en suspension (ou fluidisé) par un courant d'air ascendant injecté à sa base [...] Les matières boueuses introduites sont maintenues dans le four pendant un temps bref mais suffisant pour le séchage immédiat et la calcination. 3, record 1, French, - four%20%C3%A0%20lit%20fluidis%C3%A9

(...) vertical chambers - usually of circular cross-section - with grate hearths through which oxygen-bearing gas, usually air, is blown. As the concentrate is fed to the chamber, air is blown through the grate at a rate sufficient to hold the solid particles in suspension, the mixture of air and solids having the flow characteristics of a fluid. Since each sulfide particle is in constant turbulent motion in the furnace atmosphere, roasting is uniform and rapid, with efficient heat transfer and high oxygen utilization. 3, record 2, English, - fluid%20bed%20roaster

Dans les fours à lit fluidisé, le minerai [le zinc] est maintenu en suspension par l'air de grillage soufflé par le bas à un débit convenable. Dans certaines conditions, le lit de minerai en suspension se comporte comme un fluide; le contact air - particules de minerai est excellent, ce qui favorise la rapidité d'oxydation des sulfures. L'alimentation peut être constituée par du minerai fin ou granulé, la granulation permettant d'éviter un entraînement de poussière important. 1, record 2, French, - four%20%C3%A0%20lit%20fluidis%C3%A9
