A random sampling of the emissions of fine particulates from a variety of representative small biomass combustion boilers under actual operation conditions is performed. The fine particle emissions are measured in-situ, using an online measurement instrument. The effects of various burner configurations and combustor technical characteristics, biomass fuels and operating conditions are thus taken into consideration. The online results are compared with the standard German 1. BImSchV measurement performed in parallel by a chimney sweeper. In addition to the field measurements also laboratory measurements are performed, using the small biomass boiler of the Institute. Although the focus of all these measurements is in the online monitoring of the fine particulate emissions, all other main exhaust gas pollutants will be measured too.
This research project aims at strengthening the market acceptance of small biomass combustion boilers by investigating their fine particulate emissions under realistic conditions.
Reliable data will be collected on the characteristics and amounts of the fine particulate emissions from modern small biomass boilers to show the effect of burner type, operation modus and biomass fuel being used. The results obtained in the framework of the project with the online fine particle measurement instrument will be compared additionally with the standard 1. BImSchV value, measured by the chimney sweeper. Scientific analysis of the data will yield practical suggestions for reducing the fine particulates, highlighting the influence of the various combustion parameters on fine particle emissions.
