HOMER Grid 1.9

The generator proportion of sulfur emitted as particulate matter is the fraction of the sulfur in the fuel that is emitted as particulate matter. HOMER assumes that the remainder is emitted as sulfur dioxide. This value is 2.2% for diesel generators, according to the EPA document EPA420-P-02-016, dated November 2002, entitled "Exhaust and Crankcase Emission Factors for Non-road Engine Modeling–Compression-Ignition."

HOMER uses this value to calculate the emissions of sulfur dioxide. Note that HOMER does not use this value to calculate emissions of particulate matter. For that, it uses the particulate matter emissions factor. For details, see the How HOMER Calculates Emissions section of the help.
