The size distribution and composition of particulate emissions from three oil fired utility boilers were determined under representative nominal operating conditions. In addition, the variability of particulate size and compositional characteristics with changes in furnace excess air level and fuel atomization quality was obtained from one boiler as an indication of the fluctuations in particulate emissions which could be anticipated as a result of variable operating practices. The three test boilers included a 360 MW tangentially fired boiler, a 345 MW face fired boiler and a 150,000 lb/hr steam sendout package boiler - all burning a low sulfur (0.24%) fuel oil. The particulate emissions from the 360 MW tangentially fired boiler exhibited a submicron single mode size distribution with a number mean on the order of 0.05 microns. Reduction in excess air levels to the smoking threshold did not modify this distribution. However, reduction in the atomization quality of the fuel sprays resulted in a bi-modal distribution consisting of large (greater than 10 microns) porous particles in addition to the submicron population. Data from both the 345 MW face fired boiler and a 150,000 lb/hr steam sendout package boiler showed a bi-modal distribution under normal operating conditions. Particulate composition analyses demonstrated increases in carbon for both the reduced excess air and reduced atomization quality tests. Sulfate emissions were also found to increase for the atomization tests. Scanning Auger microprobe analysis combined with an argon ion milling technique indicated that this sulfate was found as a surface layer on the large carbonaceous particulates emitted under this operating condition.
