    摘要: A matrix bed is disclosed in which a non-planar reaction wave front is formed during operation. This is accomplished by heating the matrix bed, containing heat-resistant material, until at least a reaction portion of the matrix bed is above the temperature required for a plurality of reactant gas streams to react. Next, the reactant gas streams are directed through the matrix bed in a manner so as to form at least a Bunsen, Burke-Schumann, inverted-V, or some other type of non-planar reaction wave front at the portion of the matrix bed that is heated above the reactant gas streams reaction temperature. At the non-planar reaction wave front, the reactant gas streams react to produce a reaction product gas stream that is then exhausted from the matrix bed.

    摘要: A method and system for reducing pollutant concentration within an internal combustion engine exhaust stream is disclosed. Soot and products of incomplete combustion in the engine exhaust stream are destroyed by oxidizing them in a flameless thermal oxidizer that contains a matrix of heat-resistant media. Methods and systems for increasing particle residence time within the thermal oxidizer are also disclosed. These techniques include employing electrostatic precipitation, centrifugal force, and particle impaction sections. A method and system for reducing oxides of nitrogen (NOx) emissions is also disclosed. Low NOx concentration may be obtained by adding a SCR system after a thermal oxidizer, by tuning the engine to produce low NOx/high soot and destroying the soot in a thermal oxidizer, and by injecting a reductant into the thermal oxidizer. The flameless thermal oxidizer may be located between the engine and a turbo-charger to enhance thermal efficiency and to reduce turbo-charger wear. The thermal oxidizer comprises longitudinal and radial flow systems, which each may include a reaction wave of the following shapes: planar, cylindrical, Bunsen, Burke-Schumann, and an inverted V. An engineered matrix is disclosed to manipulate the shape of the reaction zone.

    摘要: An improved method and apparatus is provided for thermally reacting chemicals in a matrix bed of porous inert media. The reaction is conducted in an apparatus that is capable of establishing and maintaining a non-planar reaction wave within the matrix bed. The positioning of the non-planar reaction wave permits the interior surfaces of the vessel to be maintained at a temperature at least above 175.degree. F. The apparatus includes a vessel that contains the matrix bed; one or more feed tubes that extend into the matrix bed, where preferably an exterior portion of each of the feed tubes that passes through the vessel is insulated; an exhaust outlet; and a means for heating the matrix bed. The non-planar reaction wave is established by heating at least a portion of the matrix bed to at least the reaction temperature of the chemicals and feeding a process stream containing the chemicals to be reacted into the feed tubes. Upon exiting the feed tubes, the process stream is reacted in a non-planar reaction wave to produce heat and the reacted process stream. The heat from the non-planar reaction wave maintains the interior surfaces of the vessel at a temperature of at least 175.degree. F. during operation of the vessel. The reacted process stream is then directed to the exhaust outlet of the vessel.
