Description:
An experimental study was conducted to determine the reliability of the Method 5 procedure for providing particulate emission data from an oil-fired steam generator. The study was concerned with determining whether any 'false' particulate resulted from the collection process of from the collected particulate. Variations to Method 5 tested included filter media, size and temperature, nozzle type and sampling duration. Tests were conducted at a 350 MW source utilizing low sulfur residual fuel. Two series of field tests were conducted. In both cases simultaneous samples were collected with two trains. In all cases one train was the standard Method 5 train. The other train was either a modified Method 5 train with an in-stack filter or a second standard Method 5 train. Runs were preformed in which one or both trains were spiked with SO2 at the nozzle to provide sampled gas stream concentrations of approximately 2000 ppm SO2 approximating a high sulfur fuel. By comparing particulate and sulfate distributions between probe and filter catches for the two trains, no evidence for the formation of 'false particulate' for the condition evaluation were found. The in-stack filter method used has several advantages over EPA Method 5 including the elimination of recovering the probe catch.
