AIR CURTAIN INCINERATOR TESTS
ABSTRACT The use of an curtain incinerator to dispose of materials recovered from an oil spill was investigated for the Alaskan Beaufort Sea Oilspill Response Body (ABSORB). A series of combustion experiments was conducted in a prototype incinerator 10 feet wide by 10 feet long by 14 feet high. Combustion rates, emissions, and temperatures were monitored during the experiments. Operating variables investigated included air flow rate, direction of air into the combustion chamber, waste feed rate, water spray over the combustion zone, and the slant of the combustion chamber's front wall. Some of the major results were:Optimum air flow rate into the incinerator is 7,000 cubic feet per minute.The system performed satisfactorily at combustion rates exceeding 600 barrels per day.At 600 bbl/day, most emulsions burned with emissions less than 1 Ringelmann.Oil with 20-to-30 percent water burned most efficiently.Oil-saturated straw was consistently burned in the incinerator at measured emission levels of less than 1 Ringelmann.Combustion temperatures in the incinerator will exceed 2,000°F with an 18,500-Btu-per-pound oil. Included in this paper are details of the test system, results of combustion tests, and recommended design criteria for an arctic system.
