Incineration of Nitrogen-Bearing Wastes

Incineration is perhaps the safest and most effective method for the disposal of many industrial wastes. Practically all organic compounds can be incinerated with an assured level of destruction. When burning hydrocarbons, the combustion process produces an, H2O and some "allowable" quantities of un burnt hydrocarbons, CO and oxides of nitrogen (NOx). Single-stage burning of wastes containing bound nitrogen can produce NOx emissions exceeding those dictated by environmental concerns or mandated by regulatory agencies. The incineration of nitrogen-bearing wastes, thus, requires a specialized approach. John Zink Company's NOxidizer incinerator employs a proprietary three-stage incineration process that limits NOx formation when burning these wastes.
