Abstract:
As the German energy policy promotes the development of biomass as primary energy source, the total number of small scale furnaces in Germany has significantly increased in the past 10 years. This leads to a higher overall pollutant emission contribution by these facilities. The amendment in 2010 of the 1st German Federal Immission Protection Ordinance (BImSchV) reflects this development. As most furnaces are tested just under laboratory conditions, their range of emissions under service conditions is largely unknown. This paper presents the results of field measurements at 9 different furnaces (< 50 kWth) which burn biomass fuels such as pellets and wood logs. The measurements took place in Hamburg and the surrounding area during the heating period 2010/11. Purpose of these measurements is to highlight the representative range of actual emissions emitted by small scale furnaces operated in Germany. During each measurement the instantaneous flue gas particle size distribution is measured online with an electrostatic counter. The total dust loading in the flue gas is determined gravimetrically in two ways: by the standard German chimney sweeper method and also with the more rigorous approach of DIN 2066. The concentrations of O2, CO2, CO and NOX in the flue gas are monitored at the same time.
