Corn Residue Furnace Emissions
ABSTRACT MASS emission rates and aerodynamic size distributions of particles emitted from biomass furnaces are included from tests of (a) A direct combustion cob and stalk burner built by Sukup Mfg. Co.; (b) An updraft gasifier corncob furnace built by Clayton and Lambert Mfg. Co.; and (c) A downdraft channel gasifier corncob furnace being developed by Purdue University and USDA, ARS. Particulate mass emissions from these biomass furnaces and gasifiers were found to be substantially greater than from a liquid petroleum burner and also greater than the EPA's New Source Performance Standards (NSPS) for very large coal fired boilers. The aerodynamic size distribution of the particles being emitted from the Purdue USDA downdraft gasifier was found to be approximately log-normal with a mass median diameter of 0.2 microns. About 90 percent by weight of the particles were found to be less than 1.0 micron in size..
