Variables Affecting Emission Measurements from Domestic Wood Combustion

Abstract

Wood heating is an important worldwide source of emissions of particulate matter, comprising black and organic carbon. In Norway, woody biomass combustion is a significant source of particle emissions. In 2013 about 1.2 billion tons of wood logs were burned, according to the response from annual questionnaires made by statistics Norway. About 1.0 million tons were burned for household heating. About 54% of the wood was burned in stoves with new combustion technology (in 550 000 stoves) while the remaining wood was burnt in old stoves (in 420 000 stoves). The motivation of this investigation is to highlight the impact of some of the most important variables inherent to two different wood stove test standards, i.e. the EN 13240 DIN+ with heated filter method and the NS3058-59 full flow dilution tunnel method with ambient particle sampling, regarding the total amount of measured particulate matter collected gravimetrically on standard filters supported in standardized filter holders.
