Heat from wood - Fine particle emissions: Fuel impact, furnace contest, secondary measures, characterisation and toxicity
Project
Project code: 3130002
Contract period: 01.01.2009
- 31.10.2011
Purpose of research: Applied research
Gaseous and particulate emissions are formed during complete combustion of biomass. They can ba associated with highly toxic organic compounds and polyaromatic hydrocarbons. This research aims at emission reduction for residential wood fuel appliances by different measures. Besides primary and secondary measurements the main focus is on the different properties of the fuel used as well as the influence of the user itself. In addition the toxicity of the emitted particulate matter will be determined. From the obtained results further reduction strategies will be proposed.
In this project TFZ performs combustion trials on four different combustion units including modern and simple chimney stoves, a slow heat releasing stove and a wood log boiler. For each test run the composition of the flue gases will be analysed and particulate emissions will be collected for well defined combustion batches. The particulate matter will be chemically characterized and some toxicological tests will be performed.The following parameters are of main interest: kind of fuel, moisture content, ash content, shape of fuel, size of wood log, time of reloading, frequency of reloading, amount of wood loaded as well as investigation of an air control unit behavior after false operation of the wood stove (size of wood logs and amount of wood loaded).
