    Abstract: PROBLEM TO BE SOLVED: To enable lessening the amount of residual fly ash by synthesizing simply, easily, and at low cost such a product as may be added to fire grate ash or as may have use independent of others. SOLUTION: In a method for thermally treating fly dust 10 originating in waste-incinerating equipment the waste is burned on a fire grate 4 inside a combustion furnace 1 with evolution of flue gas 11 containing fire grate ash 19 and fly dust, fire grate ash 19 is extracted from a combustion furnace 1 having a primary combustor 7 and a secondary combustor 8 and treated further, fly dust accumulated inside a boiler 2 and inside a dust-filter apparatus 3 both disposed downstream is carried outside, and at least part of this fly dust is melted or sintered and at least part of the fly dust is led back into the high temperature region of the combustion furnace 1. At this time the temperature in the high temperature region is made higher than the melting temperature or sintering temperature of the fly dust 10 and the fly dust is made to remain in the high temperature region of the combustion furnace 1 for a sufficiently long time. By doing so the fly dust is vitrified or sintered at least partially.

    Abstract: PROBLEM TO BE SOLVED: To realize a quick and accurate measurement of temperature without giving a bad effect to the flame, by disposing optical measuring sensors immediately on the upstream side from a flame front in the premixing region of a burner while directing in parallel and/or coaxially with a fuel flow being introduced into a gas turbine burner. SOLUTION: A burner 1 and a fuel line 4 coupled therewith are provided with a measuring sensor 7. The measuring sensor 7 is fixed to a premixing region 3 substantially in parallel with the direction 5 of a fuel flow or disposed in the center of the fuel line 4. The measuring sensors 7 are directed toward all flame front 8. Numerical aperture of the measuring sensors 7 is set such that a conical observation capacity including a flame front region essential for combustion process is opened and the flame front 8 is observed from the upstream side. Even if the flame 8 vibrates in a plane perpendicular to the flow direction 5 due to thermoacoustic vibration of a burner, it has substantially no effect on the optical temperature measurement.

    Abstract: PROBLEM TO BE SOLVED: To heat a tape of fiber composite material over a wide area at a high speed so as to obtain a high speed welding by arranging at least one extending heating element in a heater. SOLUTION: A heater comprises at least two partial heaters controllable individually. In each of the partial heaters, at least one heating element is arranged. A fiber composite material tape 16 is sent to a heater 14 through a bottom plate 17. The heater 14 comprises a supplying conductor 6 for supplying hot gas. The fiber composite material tapes 15 and 16 are heated at their surfaces facing the heater 14 by the heater 14 up to at least a melting point of the base material of the fiber composite material tape. Accordingly, the fiber composite material tapes 15 and 16 are heated to the melting point or higher of the thermoplastic base material over only small parts of their thickness.

    Abstract: PROBLEM TO BE SOLVED: To provide a current limiter in which almost equal partial currents flow through two operating resistors connected in parallel at a branch point, low-inductance resistor paths are overlapped in the same region of the resistors, and the partial currents flow in opposite directions, thereby reducing inductance. SOLUTION: PTC resistors 21, 22 are electrically insulated and has a slight space therebetween. The PTC resistors 21, 22 are constructed by metal braid, metallographic structure, or porous metal babbles and are kept at a proper operating temperature by blast air cooling. The meanders or resistor paths 21a to 21c and 22a to 22c of the PTC resistors 21, 22 are connected by electric contact bridges 23, 23' and 24, 24'. The sum current is divided into partial currents 11, 12 which are equal and flow in the opposite directions through the meanders 21a to 21c and 22a to 22c which are folded in the vertical direction. As a result, the PTC resistors 21, 22 have small inductance.

    Abstract: A method of applying a metallic bonding layer for thermally sprayed ceramic heat insulating layers (6) on metallic components involves (a) applying a binder onto the degreased and oxide-free metallic surface of the substrate material (2); (b) applying metallic bonding powder (4) uniformly onto the binder; (c) applying solder powder (5), of smaller particle size than the bonding powder (4), uniformly onto the binder; and (d) drying the binder and heat treating to effect soldering. In an alternative method, an oxidation and corrosion resistant layer is produced on the cleaned metallic surface by gas-shielded plasma spraying prior to step (a), the bonding powder is a coarse powder having the same composition as this oxidation and corrosion resistant layer, step (c) is omitted and step (d) comprises drying the binder and then heat treating (solution annealing) to form a sintered bond between the metallic component and the oxidation and corrosion resistant layer and between the oxidation and corrosion resistant layer and the bonding powder. Also claimed are metallic bonding layers produced by the above methods.
