Abstract:

Due to the increasing use of biomass for heat and power generation in Europe the impact of these technologies on pollution, especially concerning particulate matter, increases. Accordingly, in Germany the maximum permissible values for particulate matter emission of new small scale combustion units where lowered recently from 150 to about 20 to 40 mg/m³ in the future (at standard conditions, 13% O2) depending on the combustion system. This has fueled the interest in particle precipitators. There are several test set­ups conceivable, each of them showing specific pros and cons. In most cases though, parallel sampling up­and downstream of the precipitator yields reliable precipitation rates. As known from the literature, electrostatic filters yield precipitation rates of up to 90 % when applied to furnaces burning woody fuels. The emissions derived from the combustion of agrofuels however differ decisively from those caused by woody fuels. The precipitators thus have to be further optimized before they can be used on agrofuel furnaces. Several precipitators showed fouling due to insufficient removal fixtures quite rapidly leading to failure. The evaluation of precipitators for furnaces therefore must include not only the separation efficiency, but also criteria such as operation safety, long time operation and the hazards accompanied with the handling of wastes.
