Studies on characteristics of fine particulate matter emissions from agricultural residue combustion

Biomass burning is largely divided into six types: open burning, agricultural waste burning, meat and fish roasts, wood stoves and boilers, furnaces, and charcoal burners. Biomass burning is largely characterized by incomplete combustion due to the difficulty of appropriate control, which results in the emission of a large amount of air pollutants and the generation of harmful substances such as volatile organic compounds (National Institute of Environmental Research, 2014). Burning agricultural residue releases a large amount of fine particulate matter (PM). Open burning of agricultural residue, burning agricultural residues without incineration facility, in the rural areas are frequently observed Therefore, management based on accurate analysis of emission characteristics is needed. In Korea, most agricultural residues except for rice straw are incinerated in the field. Agricultural residues with a high incineration ratio are Chili and Perilla. The characteristics of PM emission by agricultural residues combustion were analyzed for Chili and Perilla. PM measuring equipment are Stack sampling system and Cascade Impactor (PM10, PM2.5 Impactor, Johnas, Paul Gothe GmBH). This study, the emission characteristics of PM-10, PM-2.5 generated in the combustion of agricultural residues were examined in consideration of moisture content.
