Abstract: A gas inlet manifold for a plasma chamber having a perforated gas distribution plate suspended by a side wall comprising one or more sheets. The sheets preferably provide flexibility to alleviate stress in the gas distribution plate due to thermal expansion and contraction. In another aspect, the side wall provides thermal isolation between the gas distribution plate and other components of the chamber.

Abstract: The invention relates to a glassmaking furnace regenerator including a stack of several rows of refractory members defining a plurality of channels, characterized in that the stack comprises, in the hot gas flow direction, a first zone at the hot gas inlet, for rapidly cooling the hot gases, a second zone, or central zone, for condensing and trapping chemical species liable to generate dust, and a third zone, at the cooled gas outlet, for evacuating condensates, the rows of stacked refractory members constituting said central zone including at least two adjacent rows whose channels have a projected surface area at least 20% less than those of the channels of the first and third zones.

Abstract: Provided are novel gas permeable bricks of a refractory material suitable for use in a hot grid of a regenerative heat exchanger. In accordance with one aspect of the invention, the brick has an inner face and an outer face on opposite sides of the brick. One or more cavities extend from the inner face partially into the brick. A plurality of channels for each of the cavities extend from the outer face to the cavities. The cavities and channels allow a gas to pass through the brick. Also provided is a hot grid suitable for use in a regenerative heat exchanger formed from a plurality of the bricks.

Abstract: An apparatus for treating gaseous pollutants in an air stream such as a regenerative thermal oxidizer or a selective catalytic reduction system, including a reaction chamber wherein the reaction media bed within the chamber comprises a plurality of nonprismatic ceramic blocks each having end faces, side faces and a chamfered face extending at an angle relative to the side faces of the blocks. The ceramic blocks are stacked in end-to-end and side-to-side relation within the reaction chamber and the ceramic blocks each include spaced parallel passages extending through the end and chamfered faces. The chamfered faces of adjacent blocks form voids between the blocks promoting turbulent gas flow through the voids and equalizing the pressure within the reaction chamber.
