The 20/20/20 target for Europe, will lead to an increased use of biomass combustion, e.g. using wood logs and wood pellets. On the other hand, the Air Quality Directive (2008/50/EC) lies down stringent requirements on maximum levels of particulate matter (PM) in the ambient air. Domestic wood combustion emits particulate matter (PM) which are of concern to authorities and the public. Several different methods of PM measurements have historically been used to perform type testing of solid fuelled residential appliances and boilers. This method shall give repeatable results that are of a guaranteed traceable accuracy, and by this means give the consumer reliable information on the suitability of a particular appliance or boiler. One of the main methods used in Europe consists of sampling the solid fraction of aerosols using a heated filter, this method does not include the collection of the condensable fraction, OGC measurements are performed using FID method.The aim of this work carried out within the EMPIR IMPRESS2 Project was to evaluate the performances of this method by performing intercomparisons using a stack simulator generating real biomass combustion gases.
