The paper gives results of measurements of emissions from a prototype catalytic and a generic noncatalytic stove over a range of burnrates. For the catalytic stove, simultaneous EPA Modified Method 5 (MM5) samples were obtained before the catalyst and in the stack. For both stoves, Oregon Method 7 (OM7) and Condar dilution samplers (CDS) were operated simultaneously with the MM5 train at the stack location. Volatile organic samples were obtained by integrated bag sampler at the stack location. Results show a generally predictable correlation between MM5, OM7 and CDS results. Emission rates, based on MM5, were about twice those based on OM7 and CDS. Catalyst emission reduction effectiveness (by MM5) ranged from 72 to 98%. Catalyst inlet emissions appear to be affected by the test sequence: a high burnrate test produced higher emissions when preceded by a low burnrate test than when preceded by a high burnrate test. Volatile organic emissions were about the same at all burnrate on the catalytic stove and at low burnrates on the noncatalytic stove. At a high burnrate, the noncatalytic stove produced substantially less. All MM5 samples tested positive for polynuclear aromatic hydrocarbons.
