During the first week of April, 1991 the Wisconsin Department of Natural Resources (WDNR) conducted a series of air emissions tests of a small industrial wood-fired boiler in northern Wisconsin. The boiler was firing a virgin hogged wood/wood waste fuel with a moisture content of about 35 percent The pollutants measured were particulates, nitrogen oxides (NOx), carbon monoxide (CO), total hydrocarbons (THC), benzene, formaldehyde (CHOH), polycydic organic matter (POM, eg. benzo (a) pyrene), aldehydes, and trace metals (As, Ba, Cu, Pb, Mn, Ni, K. Se, Na, and Zn) For two and a half days continuous emissions data were recorded by laboratory-certified continuous emissions monitors for CO, NOx, O2 THC, and CO2 while the EPA reference method stack tests were being conducted for the other pollutants. In addition, a WDNR test team measured CO, O2, and flue gas temperature with a Rosemount portable combustion analyzer for several hours over the course of those two and a half days The principal purpose behind the study was to evaluate the hazardous air emissions potential of a small industrial furnace firing a virgin wood fuel To that end, it was hoped that a surrogate pollutant could be identified which would represent the levels of hazardous air emissions (eg, benzene) present in the wood-fired furnace flue gases. If a readily monitorable pollutant could be identified, then a regulatory strategy of measuring one representative pollutant could be put in place to continually assess the hazardous emissions potential of virgin wood combustion.
