<p>The present invention discloses the disposal of halogenated hydrocarbon waste materials which are burned in a horizontal fire tube boiler (10). In the disclosed and illustrated embodiments, liquid and/or gaseous waste of highly chlorinated hydrocarbons are input along with a flow of fuel oil or gas as required to increase combustion temperature. While high combustion temperatures are achieved, a stable flame front is established. A refractory lined combustion chamber (12) of substantial length is incorporated to contain the flame front near adiabatic conditions for sufficient dwell time so that the combustion gases leaving the vicinity achieve near complete combustion. Before entering the water jacket boiler furnace tube (34) the temperature of the flue gas is dropped to a level enabling the use of standard materials of construction of the tube sheets of the boiler, where the fire tube boiler is most vulnerable to corrosion from excessive temperatures and condensation chlorinated hydrocarbons reacting on the interior thereof. The tube sheet boiler permits burning of halogenated hydrocarbon waste with minimal support fuel requirements to yield flue gas containing exceptionally high hydrogen chloride concentration.</p> |
