    摘要： The present invention relates to a method of decomposing organochlorine compounds such as dioxins reductively or catalytically. The organochlorine compounds such as dioxins and o-chloroanisole are decomposed in an aqueous alkali solution in the presence of a reducing agent or a catalyst. The alkali which can be used is at least one selected from the group consisting of sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate and aqueous ammonia. The reducing agent which can be used is at least one selected from the group consisting of sodium hydrosulfite, ascorbic acid, hydrazine, hydrazine hydrate, neutral hydrazine sulfate, hydrazine carbonate, sodium thiosulfate, sodium sulfite, potassium sulfite, hydroquinone, 4-methylaminophenol sulfate and Rongalite. The catalyst which can be used is at least one selected from the group consisting of activated carbon and titanium oxide.

    摘要： An apparatus for incinerating a waste gas comprises a combustion furnace main body having a peripheral wall and a hearth and a plurality of flare burners disposed on the hearth. Each of the flare burners including a burner main body having a peripheral wall and a bottom wall, at least one of the walls of the burner main body being formed with air intakes, an inwardly projecting flange provided on an upper portion of the peripheral wall of the burner main body, gas-air mixture tubes downwardly extending through the flange and arranged at a given spacing, a waste gas main pipe disposed under the burner main body, waste gas branch pipes extending upward from the waste gas main pipe, and gas nozzles mounted on the upper ends of the waste gas branch pipes respectively and positioned at the lower ends of the gas-air mixture tubes. The waste gas forced out from the nozzles ascends the interior of the mixture tubes along with the surrounding air and the gas-air mixture jets out from the tubes. When the mixture is ignited and burned, the swirling air currents produced above the flange support the combustion.

    摘要： A method comprising injecting a primary fuel and air into a furnace to burn the fuel and form a first-stage combustion zone, the fuel being diluted with surrounding combustion gas and the air being supplied at a rate in excess of the stoichiometric rate required for the combustion of the fuel, and injecting a secondary fuel into the furnace around or downstream of the first-stage zone at a range approximately equal to the stoichiometric rate required for the consumption of the excess oxygen resulting from the combustion in the first-stage zone the fuel being diluted with surrounding combustion gas and to form a second-stage combustion zone around or downstream of the first-stage zone.
