Abstract:
An assembly for use in cooling a hot gas, said assembly comprising:an axially elongated coolant chamber containing a mass of a chemical coolant solid, said coolant chamber including at least one gas entrance opening and a plurality of radially distributed gas exit orifices, the chemical coolant being endothermically reactable with the hot gas to cool the hot gas and to form at least one gaseous endothermic reaction product, the mass of the chemical coolant solid being reduced when a sufficient quantity of heat is absorbed thereby, anda member interposed between the at least one gas entrance opening and the mass of chemical coolant, said member being permeable to the hot gas to permit passage of the hot gas therethrough to contact the chemical coolant, said member also being movable to cooperate with said coolant chamber to maintain a compressive force on the chemical coolant as the chemical coolant endothermically reacts and the mass thereof is reduced,with the cooled hot gas passing from said coolant chamber through the radially distributed gas exit orifices.
