  • Patent number: 5092254
    Abstract: A method and apparatus for incinerating waste material and for reducing noxious byproducts of the incineration process. The apparatus consists of a furnace having a turbulent reaction zone whereby an overfire air header and additive distributor and lime injection nozzles connected to the incinerator through a plurality of nozzles located at even distances about the arrangement is the turbulent reaction zone of the furnace such that an additive mixture is injected into the turbulent zone through and distributed evenly during combustion across the entire width of the turbulent area. As a result, a reaction between the combustion products and the additive is optimized resulting in an overall reduction in acid gas content, acid dewpoint temperature and the corrosion levels inside the incinerator and auxiliary equipment.
    Type: Grant
    Filed: May 9, 1990
    Date of Patent: March 3, 1992
