摘要： Endothermic processes are carried out in a fluidized-bed reactor which is connected to a holding reactor, solids being recirculated between the two reactors. The primary fluidized-bed reactor uses a fast-fluidized bed system in which the solids concentration decreases continuously from the bottom to the top of the reactor. After the necessary residence time in the holding reactor, solids are discharged. Solids are entrained with the gas stream from the primary reactor and are separated therefrom to be delivered to the holding reactor. The reaction is controlled by regulating the rate of recirculation of solids from the holding reactor to the fast fluidized bed reactor.

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 Solids withdrawn from the bed are cooled in a fluidized-bed cooler and the temperature of the bed is maintained constant by the controlled recirculation of cooled solids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 for metering solid present in the gas/solid stream of a fluidized-bed apparatus, in which gas and solid are present as a prehomogenized, free-flowing mixture in a fluidized bed and in which at least one outlet orifice for removal of the gas/solid stream is provided in an outflow pipe. The method provides for feeding a particulate phase and a gas phase, homogenizing the two phases in a fluidized bed, discharging the two-phase flow via a discharge pipe and injecting gas into the discharge pipe.

摘要： A dosing apparatus provides for dosing a particulate phase within a free flowing two phase flow of a gas phase and the particulate phase, wherein the two phase flow leaves a fluidized bed. The apparatus includes, at its bottom, a gas inlet mechanism to supply the gas via an orifice, and an outlet orifice with a discharge pipe. Control of the gas flow to maintain a predetermined level of the bed is attained by weighing the contents of the bed or by use of sensors within a treatment space of the apparatus. Widening mechanism may be located subsequent to the outlet orifice for widening the stream of particulate phase for exposing an enlarged surface area of particles for treatment.

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).
