摘要： A burner/injector for providing a localized impingement flame or multiple flames for scrap heating and melting through use of a fluid fuel and at least one oxygen rich oxidizing gas. The burner/injector includes a liquid-cooled combustor for generating an impinging flame directed toward a scrap pile and a structure for injecting a controllable amount of a solid carbonaceous fuel and a controllable flow of high velocity oxidizing gas into space that has been previously occupied by the impinging flame. The burner/injector may be equipped to inject a solid slag forming materials and/or slag deoxidizing materials, and/or to inject an additional oxidizing gas for burning a small portion of preheated scrap, post-combustion of CO and iron-carbon melt refining. The burner/injector may be arranged as a simple liquid-cooled combustor permanently mounted through the furnace wall or roof, and may be equipped with single or multiple channels for injection of solid material and high velocity oxidizing gas. Separate injecting lances for high velocity oxidizing gas and/or solid carbonaceous fuel may be mounted on the furnace. Both the lances and the combustors may be equipped with a nozzles for additional injection of the additional oxidizing gas. The burner/injector means can also be arranged as a water-cooled burner/injector lance accompanied with a water-cooled oxygen injecting lance, both movable through the slag door opening toward the furnace interior, wherein the combustor of the burner/injector lance may optionally be arranged (without the use of the combustion chamber) as an external combustion device.

摘要： In the case of a process for treating residues and waste materials, in particular household, commercial, and industrial trash, in a first step in the process these materials are treated thermomechanically, for example in a worm extruder, that is, in particular, heated, separated into fibers, and brought to a solid state. Then the materials in the solid state are separated selectively and subjected to a further recycling treatment.

摘要： A variable-split blowdown coal feed system supplies two streams of air entrained pulverized coal in a uniform, well-metered steady state manner. Splitter dampers control a split of a coal and air mixture into two streams which are fed to respective cyclones operated in the blowdown mode. The cyclone's exhausts are connected in common to a manifold through which a blowdown damper controls the air-to-coal ratio in the air entrained pulverized coal streams that are expressed from each cyclone's discharge.

摘要： To prevent burn-back at a coal dust injection lance which projects into a hot blast conduit of a blast furnace, cooling is effected using atomized coolant. Water is preferred as the coolant. The carrier gas used for the atomized water is either air or the oxygen which is injected through the lance for complete combustion of the coal dust.

摘要： Fuel and combustion gas are supplied to the blast pipes and tuyeres of a blast furnace through injection lances which have an inner tube and an outer tube. The inner tube is generally used to carry the fuel, while the space formed between the inner and outer tubes is used to carry the combustion gas. Such a lance can have a heat resistant tip which has a bore for forming an extension of the inner fuel supply tube, and which also has a number of helical channels disposed about the bore for forming an extension of the space between the tubes. It is advantageous to have more than one such lance in each blast pipe and to have the lances extend obliquely into the hot blast channel that is formed by the blast pipe and the tuyere.

摘要： A tuyere for a blast furnace comprises water-cooled tuyere; and a burner removably mounted inside the water-cooled tuyere to burning pulverize coal. The burner comprises an inner pipe, an intermediate pipe and an outer pipe which are concentrically arranged. The inside of the inner pipe is used for a pulverized coal path, an oxygen feed path being in between the inner pipe and the intermediate pipe and a flame temperature control gas feed path in between the intermediate pipe and the outer pipe. The burner is equipped with a water-cooled jacket outside of the top end of the burner.

摘要： A pressure-reducing device in a pneumatic transport system for particulate material having a first and a second transport channel which are arranged so that, at the transition between the two channels, the gas/particulate flow is bent through 180.degree.. After the bend, a throttling means is arranged. The throttling means consists of an annular nozzle, the inlet side thereof being rounded with an arcuate profile in radial section. The pressure-reducing device may be included in a transportation system for feeding particulate material out from a pressurized container to a container under a lower pressure, for example for removing dust from a dust separator in a PFBC plant to a collecting container.

摘要： The invention relates to a method and device for pulverizing a solid fuel material introduced inside a vessel by means of a screw conveyor through a die opening within the vessel and in which is formed by extrusion a roll of compressed material, the latter being disintegrated by at least one gas jet injected under high pressure. According to the invention the gas is injected from the inside of the conveyor and in the axis of each die, each gas jet having a sufficient momentum to form substantially a cone centered on the axis of the roll widening from the inside of the latter, each roll being constituted by a hollow tube whose inner wall crumbles and takes the shape of the jet liberating particles which are sucked into the jet and introduced into the vessel. The invention is particularly applicable to supplying a gasifying reactor.
