摘要： An industrial furnace for heat-treating metallic workpieces has separate heating and cooling chambers. The latter uses a circulating cooling gas, the flow of which against or past the workpieces produces cooling or gas-quenching. The furnace may have another chamber for oil-quenching lying below the gas-cooling chamber. In order to enable the gas cooling to operate quickly and efficiently, a cooling box fed with air by ventilator fans is provided in the shape of a tunnel, with internal surfaces above and at both sides of the effective cooling space constituted by interchangeable nozzle plates (or blank plates if no nozzle openings are desired at the top or at the sides). The workpieces to be cooled rest on a platform which may be raised or lowered to adjust the distance from the top nozzle plate or lowered into an oil bath. The nozzle plates provide a choice of nozzle patterns for different articles or groups of articles to be cooled after heat treatment. The nozzle plates may have setbacks or protrusions in order to vary the spacing of the nozzle openings from the median plane of the cooling tunnel.

摘要： The invention relates to a novel burner nozzle field consisting of nozzle field modules which work with an intensive air pre-heating system and which produce gas impact spots on the material which is to be warmed, which have an average distance of, preferably, less than 150 mm and, in the best case, less than 100 mm. The burners work with a deignited gas outlet and an individual air pre-heating system. The individual nozzle field modules can work in any particular spatial orientation. Burner nozzle fields can be arranged behind each other in order to increase efficiency.

摘要： A combustion chamber (5) for a gas turbine is adapted for flameless oxidation of fuels. This circulation flow has an internal space (9) in which a large-volume circulation flow is established. To this end, the combustion chamber supplies a hot exhaust stream to the introduced air, the mass flow rate of which exceeds the fresh air stream. The fresh air and the fuel are fed to the combustion chamber in the same direction, roughly parallel to the wall.

摘要： In order to permit operation with preheating of the combustion-supporting air to 50 or preferably 65 percent or more of the oven temperature, the air is fed to a ceramic burner tube through an annular nozzle directing it in an annular jet along the interior walls of the burner tube. For a burner of low back pressure having no restriction at the mouth of the ceramic burner tube, the ceramic burner tube fits over the end of the outer member of the annular nozzle and some of the combustion product gas, flowing from the oven into the burner structure for countercurrent of the preheating of the air supply, is sucked into the underpressure zone between the annular air jet and the inner wall of the burner tube through a small annular gap where the burner tube fits on the air-supply nozzle. For a burner design involving considerable back pressure, the ceramic burner tube fits within the outer wall of the annular nozzle with a very small clearance in the overlap and some of the supplied air, which is at higher pressure than the exit in gases, escapes through the gap around the outside of the burner tube and cools the burner tube and the adjacent overlapping portion of the air supply tube.

摘要： A ceramic recuperator (18) for a recuperator burner (1) is provided, in its heat exchanger region, with a plurality of radially inward- and outward-extending teeth. On the otherwise hollow-cylindrical recuperator (18), the teeth (19) are arranged in groups, e.g., in rings; the teeth of one ring are each offset from the teeth of an adjacent ring. Alternatively, it is possible to arrange the teeth on a single- or multi-start helical line. The recuperator can be produced economically by the slip-casting method.

摘要： A jacketed jet radiant heater for an industrial process furnace as a frame tube composed of axially aligned pipe pieces abutted on one another that are held together by clasps on the outside of the flame tube that have studs which protrude into holes in adjacent pipe pieces and have a head portion which serves to center the flame tube within the jacket tube. The clasps make it possible to provide exhaust gas releasing slots between some of the pipe pieces of the flame tube and thereby avoiding local overheating of the jacket tube.

摘要： The heat recuperator of a burner for an industrial furnace makes use of a substantially cylindrical body of ceramic produced by extrusion in which there are two interleaved sets of parallel channels, one set for the flow of combustion product gases out of the furnace and another set for the supply of air to be preheated in the recuperator and delivered to a combustion chamber coaxial with the recuperator and possibly located at least in part in the end portion of the cavity surrounded by the cylindrical ceramic body. The combustion product gases and the air being preheated flow in countercurrent and the disposition of the sets of channels facilitates heat transfer. The combustion chamber is constituted entirely of ceramic parts. A jet nozzle is provided on the outlet side of the combustion chamber and a fuel lance passing through the middle of the recuperator body and into the combustion chamber may also serve to adjust the jet nozzle by means of a valve body around its tip. Some of the air supply from the recuperator may discharge just outside of the combustion chamber so that a two-stage combustion may be provided, beginning with incomplete combustion in the combustion chamber.

摘要： A gas carbon nitriding method to produce .epsilon.-carbon nitride layers on ferrous metal substrates. The gas atmosphere comprises partially dissociated ammonia and contains between about 2 and 20% (by volume) of carbon monoxide and carbon dioxide. The treatment temperature is between 500.degree. and 650.degree. C. The process is characterized in that the average nitriding potential, p.sub.NH.sbsb.3 /p.sub.H.sbsb.2.sup.1.5 , is between 0.5 and 5, and the partial pressure ratio, p.sub.CO /p.sub.CO.sbsb.2, is between about 1 and 10.The gas atmosphere is formed by introducing into the furnace chamber (a) an ammonia-containing gas, and (b) a combusted gas containing carbon dioxide.

摘要： An industrial burner with low NO.sub.x emissions, particularly for heating furnace chambers of industrial furnaces, has a high-heat-resistance combustion chamber (9), which is formed with a fuel supply device and an air supply device and with at least one nozzle-shaped outlet (10) for the gases emerging into a heating chamber. The fuel supply device (17, 18) extends through the combustion chamber, which is acted upon constantly with air. The fuel supply device can be switched over between two operating states, with a differing three-dimensional location of fuel nozzle devices (25, 26) relative to the combustion chamber outlet. In a first operating state, fuel is introduced into the combustion chamber, creating a fuel/air mixture that burns with a stable flame in the combustion chamber, and in a second operating state, the reaction between the fuel and the combustion air is substantially shifted into the heating chamber.

摘要： A burner suitable for heating a furnace chamber of an industrial furnace which is equipped with a recuperative preheater for combustion air has a combustion chamber at one end and a feed-through cap at the other end which is accessible outside of a furnace in which the burner is installed. The tubular recuperative preheater is of the coaxial countercurrent flow configuration extending between the combustion chamber and an annular outflow collector cap. A coaxial fuel pipe is centered in the burner extending to the combustion chamber. Overheating of the burner cap is prevented by means of a spacer sleeve of small heat conductivity interposed between the preheater and the burner cap. This permits the valves to be seated in the burner cap without risk of thermal damage. For protection of personnel against contact with hot surfaces, a perforated metal shield is provided between the burner cap and the outflow cap of the recuperator, essentially covering all the portions of the burner outside a furnace wall.
