Set-up of a new sampling method to measure condensable pm from residential solid biomass heating generators

The paper aims to describe the setting up of a new sampling method for the collection of condensable PM from small heating appliances fed with wood fuels. The method is based on dilution mechanism, which takes part in a reaction chamber. The paper describes the evolution of the dilution chamber design to join the final aim to collect condensed PM. The modification of the component was decided according to three experimental tests campaigns, which make possible to verify the good operating conditions of the built sampling train prototype and to compare the PM measured with the new method with PM collected by a reference sampling method for primary PM collection. Innovhub and ENEA are working to the new dilution system to measure condensable PM in the framework of IMPRESS II, a project funded by EMPIR initiative.
