In a burner, particularly for use in a drum of a combustion furnace or incinerator for flowable, pump-deliverable waste materials, a lance is provided for introducing the fuel and a nozzle is placed on the end thereof. The lance can be surrounded by a first uncooled lining, which essentially comprises two tubular, coaxial jacket parts. The first lining is surrounded by a second lining, which once again comprises two jacket parts. The combustion air for the additional fuels in the incinerator (e.g. barrels, etc.) is introduced into the incinerator between the two linings, while the burner air enters in the vicinity of the nozzle in the first lining between the two jacket parts. Thus, important media for the actual combustion process can be directly introduced to the burning point within the incinerator via the burner.

Burner for use in a rotary drum of a combustion furnace

Chlorinated hydrocarbons are separated from refuse, typically municipal refuse, and combusted in a separate combustion chamber within an incinerating furnace, the special combustion chamber being separated spatially, and the material containing the chlorinated hydrocarbons being separated from refuse, so that combustion gases arising from incineration of the chlorinated hydrocarbons are kept separate from the combustion gases arising from incineration of the refuse. The chamber is of such size and shape that the chlorinated combustion gases are retained therein for a dwell time of at least one second, separate from the refuse combustion gases, to be then mixed with the cooler combustion gases resulting from incineration of the refuse, so that, upon mixture, the chlorinated hydrocarbon combustion gases will be cooled, the mixture then being purified for example by washing with water or reacting the mixture with reactants which bind hydrochloric acid and combustion compounds, the purified gases then being conducted for further disposal, for example by venting to the atmosphere.
