Fine particle emissions from combustion of wood and lignite in small furnaces

Vol. 37, nr 2

123-132

Assessment of household combustion emission was carried out based on data on meteorological conditions in heating season (outdoor temperature) and the emission factors. Available emission factors, both for various fuels and for various combustion devices differ markedly. The results of experimental determination of particle matter emissions, including dividing total suspended particulate matter into various fractions (PM10 and PM 2.5) have been presented in the paper. Various combustion devices to burn wood and lignite were used in experiments. Samples were taken in a dilution tunnel with the help of an impactor. It was found that specific emissions differ significantly during the combustion cycle. Compared to the used emission factors, differences are evident. It was found that TSP specific emissions depend mainly on the type of construction not its age.
