Effect on Emissions of Particulates, Hydrocarbons, Nitrogen Oxides, Lead, and Iron from Using Waste POL as a Supplement to Heating Plant Fuel.

Stack emission tests were conducted at three Air Force heating plants to determine the effect on stack emissions resulting from the use of Air Force waste petroleum fuels and lubricating oils (POL) as a supplement to heating plant fuel. Particulate emissions were unaffected by (1) 11% waste POL (by volume) with 89% no. 5 fuel oil and (2) 4% waste POL with 96% no. 2 fuel oil. Particulate emissions were increased by (1) 16% waste POL with 84% no. 2 fuel oil and (2) 16% waste POL with 84% (by heat content) natural gas. Hydrocarbon and nitrogen oxide emissions were unaffected by any percentage of waste POL up to 26% by volume. Lead emissions were increased by all percentages of waste POL except in one test when only 2% waste was used. Emission codes were not violated by the use of waste POL IN ANY TESTS. (Author)
