Abstract
An apparatus for treating gas introduced into a vessel containing a particulate material at a temperature less than that of the gas in a manner so that said material reduces the temperature of the gas and the gas entrains at least a portion of the material. The entrained material is then separated from the gas and passed to a heat exchanger to cool the material while the separated gas is passed to a turbine to drive same. At least a portion of the exhaust gas from the turbine is passed to the heat exchanger in a manner to fluidize the material in the heat exchanger and the cooled separated material is returned back to the vessel.
