ABSTRACT
This chapter reviews literature reporting emissions of biomass and fossil fuels likely to be used indoors, and focuses on emissions from gas appliances, kerosene burners, sterno burners, and woodburning. Laboratory and field studies characterizing the emission from combustion appliances show considerable variation in the emission species and emission rates. The complex of hydrocarbon molecules and the physical state of the fuel will influence its combustion properties. Emission rates and the constituents are directly influenced by combustion conditions. The maintenance of a combustion device should affect combustion efficiency and, hence, emission rates. Unfortunately, almost all of the experience with emission testing has been in the laboratory. The use of the combustion devices indoors may lead to unhealthy pollutant concentrations. Emission factors for two commonly used camping combustion appliances were determined in a laboratory study and are reported here. A ventilation system was built that vented off the combustion gases to be analyzed.
