Abstract
Abstract A combustion product processing device for use with a furnace or other burner which includes means for imparting a helical flow pattern to an influent gas stream entering a smokestack generally axially thereof wherein the stack has inlets for additional combustion air and means such as a gas jet or the like to promote ignition of at least those portions of the combustion products passing nearest the sidewalls. The tangentially injected, higher velocity gases impart a swirling action to the slower, axially flowing combustion products, causing an overall helical combustion product flow pattern, resulting in virtually complete combustion of the products. By reason of longer dwell or residence time within the tack, higher pressures caused by centrifugal force, and higher temperatures causing combustion rate increases, greatly decreased emissions result. In one embodiment the top or outlet end of the stack is fitted with a heavy particle separator adapted to collect particulate residues, or denser gases for subsequent treatment or collection, and in most other embodiments, means are filled at the outlet end of the stack to minimize axial flow and promote helical flow therefrom.
