Abstract EPA is investigating interface systems for stack gas conditioning so that various pollutant gas monitors can be adapted to source monitoring. One of these systems is the disc diluter. The system dilutes high concentration stack gases and conducts them to a point outside the stack where ambient air monitors can by used to measure the concentration. The prototype was designed to (1) provide the necessary dilution to be compatible with ambient air sampling devices for SO2 and NOx, (2) reduce the particulate and water vapor level to values that will not interfere with the ambient air sampling devices, and (3) be simple to operate and reliable for long-term sampling programs. The prototype disc diluter was constructed and laboratory tested to determine its operating parameters. Following minor modifications, the prototype was field tested at a coal-fired electric generating plant and on a gas-fired steam generator.
