Holzfeuerungen. eine bedeutende Quelle von Feinstaub in der Schweiz

Wood is a renewable energy source. Wood combustion for heating purposes therefore helps in reducing CO2 emissions. However, it often results in high emissions of particulate matter (PM) which includes both black carbon (BC) and organic carbon (OC). PM has adverse health effects and should therefore be minimized. This paper reports on the latest methods to quantify the contribution of wood combustion to PM load and gives values for PM, BC, and OC from wood combustion at a number of different sites in Switzerland. State of the art methods to characterize emissions are presented and examples are given. It is shown that a major fraction of the emissions stems from small wood stoves, where the emissions are especially high during the starting phase. In addition, these small furnaces emit large amounts of gases which are rapidly oxidized and form secondary aerosols in the atmosphere. Improvements in the emissions of small wood stoves can be achieved by an increased deployment of pellet ovens, by the development and application of new technology for exhaust gas cleaning, as well as through other ways of wood usage.
