Abstract: Provided is a reactor including a core; and a case housing the coil and the core, the core including an inner core portion arranged inside the coil and an outer core portion partly or entirely covering the outside of the coil, the outer core portion being formed of a mixture of a magnetic material and a resin. The coil is arranged such that the axial direction of the coil is substantially parallel to a bottom surface of the case. The difference in concentration of the magnetic material in the outer core portion in the axial direction of the coil is smaller than the difference in concentration of the magnetic material in the outer core portion in a direction along a side wall of the case. With the reactor, even if the outer core portion covering the outside of the coil is formed of the mixture of the magnetic material and the resin, a desirable inductance value can be easily achieved and the reactor can have good heat radiation performance.

Abstract: A reactor-use component which provides improved workability in assembling into a reactor, and a reactor using the component are provided. The reactor-use component is for structuring a reactor including a coil 10 formed with a pair of paralleled coil elements 10A and 10B made of a spirally wound wire and a core 20 fitted into the coil elements 10A and 10B to form an annular shape. The reactor-use component includes an internal resin portion 30 that retains a shape of the coil 10, and hollow bores 30h formed by a part of the internal resin portion 30 for fitting the core 20 to inner circumferences of the coil elements 10A and 10B. By inserting internal core portions 22 into the hollow bores 30h and joining opposite ends of the internal core portions 22 to exposed core portions 24, the reactor 1 can be obtained. Because the internal resin portion 30 retains the coil 10 in a state incapable of expanding or compressing, the workability in assembling into the reactor 1 can be improved.

Abstract: In a method for treating a combustion exhaust gas from a waste burning facility, the exhaust gas has its temperature lowered to 180-230.degree. C., in a temperature lowering unit, is freed of dust in a dry dust collector, passed through a dioxin and NOx removing unit using a vanadium oxide-based catalyst and, thereafter, the exhaust gas at 180-230.degree. C. is further passed through a heat exchanger to effect heat recovery. The vanadium oxide-based catalyst is a vanadium oxide alone or the combination thereof either with an oxide of at least one element selected from the group consisting of molybdenum, tin, yttrium, boron and lead or with gold. In addition, a tungsten oxide may be used. These catalysts are preferably carried on titania for use. The method and an apparatus for implementing it require a simple system configuration and yet assure high thermal efficiency while achieving efficient removal of dioxins and nitrogen oxides.

Abstract: An internal recycling type fluidized bed boiler includes a primary fluidized bed incinerating chamber constructed by an air diffusion plate, and an inclined partition wall provided above a portion of the diffusion plate where the mass flow of the air injected from the diffusion plate is greater than that from another portion so as to interfere with the upward flow of the fluidizing air injected from that portion and deflect it towards the portion above the diffusion plate where the mass flow of gas injected is smaller. A thermal energy recovery chamber is formed between the inclined partition wall and a side wall of an incinerator. The inclined partition wall is inclined by 10.degree.-60.degree. relative to the horizontal and is arranged such that the length of its projection in the horizontal direction is 1/6-1/2 of the horizontal length of the bottom of the incinerator bottom.
