ABSTRACT:
In a device for raising the temperature of a plurality of solids which utilizes a heating chamber having at least one hot flue gas inlet and one or more solids inlet apertures to supply concurrent flows of solids and hot flue gas to a heating chamber, and, which utilizes at least one disengager to deflect the heated solids and prevent the solids from being exhausted from the heating chamber along with the hot flue gas, means are provided for coaxially mounting at least one hot flue gas outlet downstream of and displaced from at least one of the solids inlet apertures. Additionally, an individual disengager is associated with each hot flue gas outlet, each disengager being coaxially aligned with and positioned intermediate its associated hot flue gas outlet and a corresponding solids inlet aperture. Each individual disengager is positioned within a direct flow path of solids from a single solids inlet aperture, to prevent thermal stressing of the individual disengager.
