摘要： A process for afterburning and purifying process exhaust gases, which contain combustible constituents, wherein the process exhaust gases and the oxygen-containing gases required for a combustion are separately supplied to a fluidized bed reactor of a circulating fluidized bed. In the fluidized bed reactor, the gas velocity is adjusted to 2 to 10 m/s (empty pipe velocity), the mean suspension density is adjusted to 0.1 to 10 kg/m.sup.3, the temperature is adjusted to 700.degree. to 1100.degree. C., and the stoichiometric ratio of gas-purifying agent having a particle size d.sub.p 50 of 30 to 200 .mu.m to pollutant contained in the process exhaust gas or formed by the combustion is adjusted to 1.2 to 3.0, calculated as Ca:S. The entrained solids in the gases from the fluidized-bed reactor are recycled to the reactor at a rate of at least 5 times the weight of solids contained in the fluidized bed reactor per hour.

摘要： A method for forming a turbulent suspension from a pulverous material and reaction gas by causing the pulverous material to flow downwards as an annular flow into the reaction chamber and by directing the reaction gas downwards inside the annular flow of the pulverous material, in which the suspension is produced by bringing the reaction gas into a high-force rotary motion and by then causing it, throttled, to discharge into the reaction chamber so that in the reaction chamber it meets on its outside a substantially vertically downward annular flow of the pulverous material, this flow being formed by utilizing the kinetic energy of the falling pulverous material on a convergent conical glide surface. An apparatus for forming a turbulent suspension from a pulverous material and reaction gas, which apparatus is adapted to be directed centrally downwards into the reaction chamber and consists of a feed pipe for the pulverous material, means for dividing the pulverous material and of a turbulence chamber for reaction gas, in which the feed pipe for the pulverous material has the shape of a downwards convergent cone, and inside the feed pipe there is an axially mounted turbulence chamber at the upper section of which there is a turbulence generator, and the lower section of the turbulence chamber comprises a cylindrical stabilizing member with a diameter less than that of the turbulence chamber.

摘要： An apparatus and method for combusting carbonaceous fuels includes a reaction chamber defining a reaction zone and means for injecting fuel and oxidizer gas in a manner to produce in the reaction zone a wheel-type flow of the fuel-gas mixture. In preferred embodiments, the high velocity wheel-type flow operates to suspend fuel or other reactant particles in the swirling gas for residence times required for substantially complete reaction of the particles prior to the particles impinging against the walls of the reaction chamber. High angular veocities and the resulting centrifugal forces operate to remove substantially all slag from the gas as it approaches the downstream end of the reaction chamber. Operating temperatures are maintained at a level to avoid excessive volatilization of slag and thereby promote separation of liquid slag from the gaseous reaction products. Dense phase flow is employed for transporting pulverized reactants such as coal to the reaction chamber and injecting the reactants through a pintle fuel injector.

摘要： A process for the suspension smelting of sulfide concentrates by causing a suspension flowing downwards in a suspension reaction zone to impinge against the surface of a melt below the suspension reaction zone in order to unload the solid and molten particles of the suspension into the melt and by causing the gases to flow further in the suspension reaction zone countercurrently in relation to the suspension in order to discharge the gases from the upper section of the suspension reaction zone, in which sulfide concentrate and oxygen or oxygen-enriched air are fed into the suspension reaction zone symmetrically and in the form of so dense a suspension spray that the iron oxide of the high-temperature suspension is in a molten state and absorbs the free oxygen present in the suspension before the suspension, at a temperature of at least 1400.degree. C., unloads into the melt, the heat is recovered indirectly in the suspension reaction zone from the gases rising symmetrically and smoothly around the suspension, and the melt is fed from the suspension reaction zone into a separate melt reaction space.

摘要： A method and apparatus for measuring and controlling the percentage reduction of iron ore in a vertical shaft, moving bed, gaseous reduction reactor. Reducing gas comprising hydrogen, methane, carbon monoxide and carbon dioxide is fed from a source of such gas to the bottom of the reduction zone of the reactor and is heated to an elevated temperature before being introduced into the reactor. The flow and composition of the reducing gas are determined at a first location before the gas enters the reactor. The effluent gas from the reactor is cooled and its flow and composition determined at a second location after the gas has been cooled. The measured flows and compositions are correlated with the rate of sponge iron production to obtain a measurement of percentage reduction of the ore and this measurement is used, either manually or automatically, to regulate the rate of removal of sponge iron from the reactor to maintain the percentage reduction at a predetermined desired value.
