Abstract: A municipal or like refuse, from which large articles of metals have been removed, is mixed with an alkaline substance like limestone preferably in a triple screw mixer, and then advanced along the pyrolysis path in which the refuse mixture is subjected to heat from combustion gases from an incineration chamber therebelow. A portion of the pyrolyzed product is recycled to the upstream side of that path and the remainder of the pyrolyzed product is scrubbed with an aqueous medium, e.g. water and/or aqueous acetic acid and the washed pyrolyzed product is then incinerated to produce the combustion gas.

Abstract: A method and apparatus for introducing solid, liquid or gaseous fuel into a burning zone of a rotary kiln for manufacturing cement clinker. Fuel is conducted through a duct or ducts and primary air is conducted through at least two annular ducts arranged substantially concentrically with, and around, the fuel duct(s), the portion of air in one of the air ducts flowing substantially axially, whereas the portion of air in the second of the air ducts comprises air which has a rotary component about the center axis of the burner, and wherein the amount of primary air in the two portions is independently controlled, such that the two portions of primary air are mixed at a lower velocity in a collecting duct into a single primary mixed airstream having a desired axial/rotary flow characteristic, and wherein this airstream is subsequently accelerated up to a desired, higher discharge velocity.

Abstract: A cyclone furnace includes a cylindrical shaped furnace chamber having an inlet end for the introduction of fuel-air and an outlet end defining a re-entrant throat member. A monolithic deflector cone and orifice member comprised of a castable ceramic refractory material is secured to the re-entrant throat member.

Abstract: A water jacket face of a burner nozzle for a synthesis gas generator is protected from hot gas corrosion by an annular heat shield of high temperature material tiles. Angular segments of a tile annulus around a burner nozzle orifice are secured to the water jacket face by furnace melted, high temperature brazed metal. The metal water jacket face along radial joints between adjacent tiles is protected by stepped or scarfed lap joints.

Abstract: A water-cooled firing grate made up of grate bar blocks extending over the width of the grate and each having a plurality of grate bars mounted on a grate bar carrier and interconnected by connecting pieces communicating between meandering shaped channels in the grate bar and a pair of end pieces forming an inlet and an outlet at the outer boundaries of the block and connected to an inlet and an outlet for the cooling water. The pieces are so fixed to the bars that they maintain a clearance between the bars of 1 to 1.5 mm.

Abstract: A coal-burning utility electrical power generation plant includes a mill pulverizing coal and supplying same to a boiler for combustion. The boiler has a bottom ash hopper for receiving combustion products including clinkers, and a clinker grinder for grinding the clinkers.

Abstract: A waste incinerator is provided which can completely prevent environmental pollution by dioxins. Exhaust gas from an incinerator is guided into a glass melting furnace by a duct, and blown into molten glass through a bubbling pipe to decompose dioxins in the exhaust gas. High-temperature gas produced in the glass melting furnace is supplied into the incinerator by a pipe so as to burn wastes without using auxiliary fuel. Further, exhaust gas is pressurized by pressure pumps in a pipe branching from the duct, while fuel tablets to including ashes are introduced through a fuel inlet and fed into the molten glass under the pressure of exhaust gas to decompose dioxins in the ashes.

Abstract: An apparatus for the disposal of solid rocket motors which produce exhaust ases containing flammable and/or explosive products. The solid rocket motor to be burned is first detachably connected to and inserted in one end of an elongated mixing chamber which has, at an opposite end, a multi-step expansion nozzle. The rocket motor is then ignited and the exhaust gas is passed into the mixing chamber, which is sufficiently large to reduce the velocity of exhaust gases from supersonic to subsonic. Air is injected into the mixing chamber to react with flammable and/or explosive products in the exhaust gases and the resultant mixture is then discharged from the mixing chamber through a multi-step expansion nozzle to expand the gaseous mixture and, at the same time, produce substantial turbulence within the gas mixture which is about six times higher than the turbulence levels produced by a constant area circular nozzle.
