An apparatus for cleaning a reaction chamber which has a chamber, a blade apparatus and a reciprocable rotating unit. The chamber has a wall with an interior surface. The blade apparatus has at least one annular mounting member and at least three scraping blades attached peripherally about the annular mounting member and arranged in a parallel relationship to a longitudinal axis of the chamber. The reciprocable movement unit has a reciprocable member pivotally connected at a peripheral position to the blade apparatus. The reciprocable movement unit rotates the scraping blade(s) circumferentially back and forth along the interior surface of the chamber to scrape its interior surface.

Chamber cleaning mechanism

The present invention provides a reaction chamber cleaning apparatus comprising a chamber, a blade apparatus comprising at least one annular mounting member, at least four scraping blades attached peripherally about the annular mounting member, and a reciprocal movement unit for rotating said scraping blade(s) circumferentially back and forth along the interior surface of said chamber to scrape the interior surface of said chamber; said reaction chamber cleaning apparatus also comprising a vortex unit comprising a generally conical outer shell attached to and extending downwardly from the top plate top plate, and a liquid inlet arranged in relation to the outer shell to tangentially introduce liquid into the outer shell, thereby forming a laminar sheet of fluid on the inner surface of the outer shell; said vortex unit further comprising a baffle and a concentric chamber bounded by the outer surface of the baffle, the inner surface of the outer shell, and the bottom surface of the top plate. The invention also includes methods for using the reaction chamber for effluent abatement.

An apparatus and method are provided for treating pollutants in a gaseous stream. The apparatus comprises tubular inlets for mixing a gas stream with other oxidative and inert gases for mixture within a reaction chamber. The reaction chamber is heated by heating elements and has orifices through which cool or heated air enters into the central reaction chamber. A process is also provided whereby additional gases are added to the gaseous stream preferably within the temperature range of 650 C-950 C which minimizes or alleviates the production of NOx.
