    摘要: Disclosed is a process of carrying out a combined gas turbine and steam turbine process of increased efficiency.A fuel gas is produced at a temperature of from 900.degree. to 1100.degree. C. in a circulating fluidized bed by a gasification of 70 to 95 wt. % of the carbon contained in the carbonaceous material and is treated at a temperature of from 850.degree. to 950.degree. C. with suspended solids consisting of calcium hydroxide, calcium oxide and/or calcium carbonate-containing solids to remove pollutants. The main portion of the fuel gas is burnt to produce a gas which is used to operate the gas turbine and which contains at least 5% by volume oxygen and is at a temperature of at least 1000.degree. C. Combustion of the carbonaceous gasification residue to produce process steam is performed in a second circulating fluidized bed at a temperature of from 800.degree. to 950.degree. C. under near-stoichiometric conditions by a treatment with oxygen-containing gases, which are supplied on different levels in at least two partial streams and mainly consist of exhaust gas from the gas turbine. The desulfurized fuel gas is preferably cooled to a temperature in the range from 350.degree. to 600.degree. C. and is freed from halides.

    摘要: A method of and apparatus for carrying out an exothermic process in which a combustible-containing solid (e.g. coal shale, pyrite or limestone in combination with fuel oil) are burned in a fluidized-bed reactor with primary and secondary streams of oxygen-containing combustion-sustaining gas (in a volume ratio of 1:20 to 2:1) supplied at different levels so that the primary gas acts as the fluidizing gas. The gas velocities and rate of gas feeds are controlled to provide a mean suspension density above the secondary gas inlet of 10 to 40 kg/m.sup.3. The major portion of solid feed is introduced into the space below the secondary gas inlet which is maintained substantially free of internal fixtures and the effluent gases are separated from the entrained solids which are recycled to the bed. Solids withdrawn from the bed are cooled in a fluidized-bed cooler and the temperature of the bed is maintained constant by the controlled recirculation of cooled solids thereto from the cooler. The gas heated in the cooler is fed to the bed as the secondary gas.

    摘要: A method and apparatus for operating a gas turbine installation combustion chamber with liquid fuel, by means of which the NOX are similar to those for gaseous fuels. The liquid fuel (38) is evaporated in two steps in an evaporative reactor (12). The liquid fuel (38) is first atomized to a fuel vapor/liquid fuel mixture (61) by direct heat exchange with a first heat exchange medium (21). The evaporation of the remaining residue of the liquid fuel (38) takes place by indirect heat exchange with a second heat exchange medium (51). An evaporative reactor (12) is arranged which accommodates, at its inlet end, a dual-fluid nozzle (22) connected both to a liquid fuel line (19) and to a supply line (20) for a first heat exchange medium (21).
