Gas turbine engine with fluidised bed combustion

Abstract From the Canadian patent

Abstract of the Disclosure, A method of operating a fluidised bed combustion apparatus is disclosed and in which the bed of materials to be fluidised includes inert materials and particulate fuel. The method comprises supplying combustion air in substantial excess of that required for stoichiometric combustion and metering a supply of, particulate fuel into the bed to maintain the bed at a substantially constant predetermined temperature. In apparatus form, there is provided a vessel containing a fluidisable bed of inert materials and particulate fuel the vessel being, arranged to receive a supply of fluidising and combustion air and a metered supply of particulate fuel in dependence of the …
