摘要： The present application discloses a pellet flue gas circulation and waste heat utilization process and a system thereof, which relates to the technical field of flue gas treatment. The system includes a grate, a rotary kiln, an annular cooler, and ducts connecting each part. On the basis of not changing the existing process a flue gas circulation unit and intelligent control equipment are arranged additionally in the present application. The process is simple, and not only can ensure the parameter stability of the production system such as temperature, gas flow or gas pressure, but also can make full use of the low and medium temperature flue gas components and the waste heat, so as to achieve net zero waste gas discharging, energy saving and emission reduction.

摘要： A gas inerting system and method is provided. This system includes a rotary melting furnace with a furnace barrel, a burner, and a charge of metal to be melted; and an injection manifold with a plurality of injection orifices. The burner is configured to produce a flame directed into the furnace barrel, and the plurality of injection orifices are configured to disperse inert gas streams into the furnace barrel, into an inerting region between the burner flame and the charge of aluminum. The metal to be melted may be aluminum. The method of inerting includes rotating the rotary furnace and introducing heat into the furnace barrel by generating the flame, thereby beginning a melt cycle, then introducing the inert gas streams into an inlet to the injection manifold, thereby directing the inert gas streams through the injection orifices and into the inerting region, after a predetermined condition has been met.

摘要： Described is a method for the production of ferrochromium and a rotary furnace employed in such method. Raw chromium ores, fluxes and carbonaceous reducing agent(s) are charged into a rotary furnace into which oxygen or oxygen-enriched air are blown to effect smelting reduction. The layer height of the carbonaceous reducing agent and the time interval during which the layer height should be kept are specified, the reducing agent is used in circulation, while exhaust gases are utilized for pre-heating and pre-reducing of the materials for saving the energy considerably in contrast to the conventional method. The rotary furnace has plural gas-blowing, small holes passing through the furnace shell and the refractory lining. These holes may be arranged as a dual pipe whereby cooling air, fuel or a fuel-oxygen mixture may be blown or an oxidizing gas and a cooling gas such as argon may be blown through the inner pipe and the outer pipe respectively.
