Abstract
Procedure for the almost stoichiometric combustion of carbonaceous materials in the fluidized layer, with return of the discharged solids to the fluidized layer, evacuation of the combustion heat by means of cooling surfaces, characterized in that combustion is carried out with two partial streams of oxygenated gases fed at different heights, of which at least one is incorporated as a secondary gas in one or more superimposed planes; because the volumetric ratio between fluidization gas and secondary gas is adjusted to a value in the range of 1:20 to 2: 1; Because above the feed point of the secondary gas, and by adjusting the gas velocity and the ratio of fluidizing gas to secondary gas, a state of the fluidized layer with an average suspension density of 15 to 100 kg/m3; because at least a substantial part of the heat of combustion is evacuated by means of cooling surfaces located in the free space of the furnace above the point of supply of the secondary gas: because the preponderant part of the carbon material is loaded into the space practically free of internal structures, located below the secondary gas supply point, and because the solids are taken from the circulation system formed by the fluidized layer reactor, the separator and the return line.
