    Nóta "When an evenly distributed air or gas is passed upward through a finely divided bed of solid particles such as sand supported on a fine mesh, the particles are undisturbed at low velocity. As air velocity is gradually increased, a stage is reached when the individual particles are suspended in the air stream – the bed is called “fluidized”.With further increase in air velocity, there is bubble formation, vigorous turbulence, rapid mixing and formation of dense defined bed surface. The bed of solid particles exhibits the properties of a boiling liquid and assumes the appearance of a fluid – “bubbling fluidized bed”.At higher velocities, bubbles disappear, and particles are blown out of the bed. Therefore, some amounts of particles have to be recirculated to maintain a stable system – “circulating fluidised bed”.FBC BOILERS.

    Nóta "At sufficient flow rates, the bed acts as a fluid resulting in rapid mixing of the particles. Coal is added to the bed and the continuous mixing encourages complete combustion and a lower temperature than that of pulverised fuel (PF) combustion. The advantages of FBC are they produce less NOx in the outlet gas, because of lower combustion temperatures, and they produce less SOx when limestone is continuously added with the coal. They can also use a wider range of fuels than PF combustion.Reference: global-greenhouse-warming.com. Fluidised Bed Combustion, http://www.global-greenhouse-warming.com/Fluidised-Bed-Combustion.html [17.3.2017]When an evenly distributed air or gas is passed upward through a finely divided bed of solid particles such as sand supported on a fine mesh, the particles are undisturbed at low velocity.

    Sainmhíniú "dans un incinérateur utilisant un lit de sable chaud ou composé de toute autre matière granulaire, transfert direct de chaleur entre le lit et les déchets ; Dans le lit fluidisé, le sable constitue le vecteur calorifique utilisé pour atteindre une combustion totale des combustibles. Ceux-ci peuvent être des produits pâteux, voire semi-liquides comme les boues de stations d'épuration notamment. L'insufflation de l'air de combustion à travers la couche de sable provoque le soulèvement des particules et la création d'une masse en suspension dite "" lit fluidisé "". La masse de solides en suspension est composée à 99% de sable et à 1% de combustible. On obtient ainsi une combustion optimale des déchets introduits dans le four grâce à une grande surface de contact entre le sable et les déchets."

    Nóta La combustion sur lit fluidisé est apparue dans les années 50 et a d'abord concerné le grillage de minerais, les boues urbaines puis le charbon. Les applications pour la combustion des ordures ménagères et des déchets industriels ne datent que d'une vingtaine d'années.
