Abstract From the Canadian patent

Page 1, WASTE FLUID INCINERATOR, Abstract of the Disclosure An incinerator (2) particularly suited for disposal of waste fluids containing undesirable chemicals and hydrocarbons including sodium cyanide. A novel dual fuel combustion system wherein the waste fluid (48) is injected (32) intermediate an inner high temperature flame (58) and an outer somewhat lower temperature flame (60) provides a "blanket" combustion pattern. The blanket combustion pattern provides increased recirculation (61) in the combustion chamber (18), thereby increasing residence time and ensuring complete destruction of the undesirable waste hydrocarbon.
