摘要： Direct reduction process and plant for producing DRI comprising a reduction reactor and at least one reducing gas heater typically comprising a convective heating section and a radiant heating section for raising the reducing gas temperature to a level adequate for iron oxides reduction to metallic iron, typically above 850° C., wherein the reducing gas fed to the reduction reactor comprises a stream of reducing gas recycled from the reduction reactor and a make-up stream of coke oven gas containing carbon compounds which may form carbon deposits in the heating path of said heater, namely BTX and other complex carbon compounds. The heater is provided with means for feeding oxidizing agents, for example steam, steam and air and/or oxygen at predetermined heating tubes successively for eliminating the carbon deposits which may form inside the heating tubes of said heater without interrupting the operation of the plant. The make-up stream of cold COG can be combined with the recycled gas at a point in the gas heating path of the heater where the tubes have a skin wall temperature of at least 700° C., or when the mixture of recycled gas and COG is at a temperature above 700° C. for minimizing clogging or fouling of heating equipment.

摘要： An air cannon has a pressure vessel, a discharge valve, and a discharge tube assembly. The discharge tube assembly comprises a fluid passageway and a blast guard valve. The discharge valve is capable of opening and closing and allows pressurized gas to be discharged from the pressure vessel into the fluid passageway of the discharge tube assembly only when open. The blast guard valve is capable of opening and closing and obstructs the fluid passageway of the discharge tube assembly when closed. The blast guard valve allows gas to pass through the fluid passageway when open. The discharge valve and the blast guard valve are operatively connected to each other in a manner such that the discharge valve can open only when the blast guard valve is open.

摘要： A multiple hearth furnace includes an upright cylindrical furnace housing divided into a plurality of vertically aligned hearth chambers. A cleaning lance inlet port is sealingly connected to the cylindrical furnace housing and radially leads into one of the hearth chambers. A cleaning lance assembly is provided and includes an elongated mount arranged outside the furnace housing and the cleaning lance is slidably mounted on the elongated mount. The cleaning lance includes a cleaning nozzle and can be sealingly introduced through the lance inlet port along a radial trajectory into the hearth chamber by moving it along the elongated mount. The cleaning nozzle is arranged on the cleaning lance, so as to be capable of directing a jet of cleaning fluid onto a rabble arm that is positioned in a cleaning position in the vicinity of the radial trajectory when the cleaning lance is slidably moved along the elongate mount.

摘要： A hydraulic cylinder 41 of a second driver 40 brings both a scraper 20 and a first driver 30 into integrally movable relation so that the scraper 20 is caused to intrude into an uptake 10 of a furnace via an opening 14 defined on a vertical wall of the uptake 10, and an accretion removing pawl 21 is positioned on a horizontal wall surface 12 of the uptake 10. Subsequently, a hydraulic cylinder 31 of the first driver 30 moves the scraper 20 on the horizontal wall surface 12 to scrape off any accretion having occurred thereon. The accretion thus scraped is blown off the horizontal wall surface 12 by pressurized air supplied from a pressurized air-supplying source connected to a flange 27.

摘要： A method and apparatus for acoustically enhancing cooling of molten liquid. In one embodiment, a cement plant has a mill in which raw materials are mixed and ground into a powder, a kiln in which the powdered raw material undergoes a calcining process and is converted into a molten liquid known as clinker, a cooler for cooling and solidifying the clinker, and a finishing mill for grinding and mixing the clinker with gypsum and/or other raw materials. The clinker cooler has a transport mechanism for transporting clinker from an inlet end to an outlet end and a plurality of fans, located below the transport mechanism, for blowing air up through the transport mechanism and into the bottom surface of the clinker bed. The clinker cooler has one or more horns positioned on the roof of the cooler for emitting acoustic energy into the cooler. A controller controls activation of each horn independently, such that each horn may be operated continuously or intermittently. Emission of acoustic energy into the cooling chamber of the clinker cooler creates turbulence in the air and molten liquid flowing in the cooler, thereby enhancing the cooling process. The increased turbulence and energy within the cooler assists breaking up of the solidified clinker, thereby enhancing contact between the clinker surface and air.

摘要： A method of preventing dust from adhering to a wall of a combustion apparatus, such as a furnace wall or exhaust duct, is carried out by forcing gas through a porous refractory member forming the wall. Specifically, the furnace wall or exhaust duct wall to which dust might otherwise adhere is made of a porous refractory member and gas is injected through the pores of the refractory member. In an incinerator, the refractory porous member extends around the periphery of a liquid injection nozzle, so that gas fed to the inside of the incinerator through the refractory porous member prevents flower from accumulating at the periphery of the end of the nozzle and attenuates the wake of the injected liquid so as to suppress the entrainment of dust in the liquid. In a melting furnace, the refractory porous members provide the ceiling of a slag separating chamber and the entrance of an exhaust gas duct open to the upper portion of the slag separating chamber. Plate-like members form wind chambers with the porous refractory members so that cooling gas fed into the wind chambers is forced into the slag separating chamber and exhaust duct through the pores in the refractory porous members.
