The present disclosure provides a burner for a reduction reactor, the reduction reactor has a reaction space formed therein, wherein each burner has a fuel feeding hole and multiple oxygen feeding holes formed therein, wherein each burner has an elongate combustion space formed at one end of a head portion thereof, the combustion space fluid-communicating with the reaction space of the reactor, wherein the elongate combustion space has a length such that oxygen supplied from the oxygen feeding holes thereto is completely consumed via oxidation or combustion with fuels supplied from the fuel feeding hole thereto only in the elongate combustion space upon igniting the burner.

A high-temperature pyrolysis incineration apparatus that forces external air to a combustion chamber while burning an incineration processing material injected therein at a high temperature within a combustion chamber is provided. The apparatus includes an air-supply tube disposed at the center of the combustion chamber, a fuel supply pipe installed at an upper edge of the inside of the combustion chamber, a punching plate disposed at the bottom of the combustion chamber, a stirring rod rotatably installed at an upper surface of the punching plate using the air-supply tube as a fixing shaft, a heat recovery device disposed outside of the combustion chamber, and a circulation pipe extending from a lid of the combustion chamber to the outside that returns to a location corresponding to an upper portion of the stirring rod at a wall of the combustion chamber via the inside of the heat recovery device.

The invention provides a system for reducing the volume of bulk material, comprising a transportable container; a single chamber adapted to receive said transportable container; a means for establishing a plurality of controlled atmospheres within said chamber; a plurality of electrically-charged heating elements capable of heating said chamber to at least 1200 F; and an waste heat generator in fluid communication with the chamber. A method for simultaneously thermally degrading different waste differently in a single chamber, comprising filling each container within a plurality of containers with preselected waste and placing each container within the chamber at preselected positions; establishing a controlled atmosphere within the chamber and applying heat to the waste for a time and at a temperature sufficient to gasify the waste; collecting thermal degradation data during gasification; and applying the collected data to an algorithm to adjust the temperature and oxygen concentrations for each preselected position.

An abatement method is disclosed. The method comprises: supplying a combustion chamber of an abatement apparatus with an effluent stream containing a perfluoro compound, together with combustion reagents and a diluent; heating a combustion zone of said combustion chamber by reacting said combustion reagents to perform abatement of said perfluoro compound to stable by-products, said diluent being selected to remain inert during said abatement. In this way, the perfluoro or other compound is abated in the combustion chamber during the combustion of the combustion reagents, but without creating undesirable compounds such as, for example, NOx or other compounds.

A method and an apparatus for treating comminuted waste material the method comprising: a) providing a heating chamber (28) and one or more combustion heating means (40a-f) for heating the contents of the heating chamber (28), the heating chamber (28) having an inlet (21) and an outlet (22), b) feeding comminuted waste material through the inlet (21) and into the heating chamber (28); c) heating the comminuted waste material in the heating chamber (28), using the combustion heating means (40a-f), to generate a combustible gas; and d) supplying at least a portion of the generated combustible gas to the one or more combustion heating means (40a-f) for heating the heating chamber (28).

In a method for physical and thermochemical treatment of biomass, the biomass moisture content is reduced in a dryer and ammonia (NH.sub.3) is also released from the biomass during drying. The dried biomass is then either pyrolyzed in a pyrolysis reactor and the pyrolysis gas is forwarded to and combusted in a combustion device to form flue gas, or is combusted in a combustion facility unit to form flue gas. In either case the flue gas is fed to a mixer. Oxygen (O.sub.2) is metered to the flue gas in the mixer and is fed directly to the dryer as drying gas. As the drying gas passes through the dryer, the sulfur dioxide (SO.sub.2) contained in the drying gas and/or the sulfur trioxide (SO.sub.3) chemically reacts with the ammonia (NH.sub.3) to form ammonium sulfite ((NH.sub.4).sub.2SO.sub.3) and/or ammonium sulfate ((NH.sub.4).sub.2SO.sub.4). Also a treatment facility physically and thermochemically treats the biomass.
