“…The Figure shows that flue gas mainly contains solid particles with diameters from 0.3 to ~ 20 μm. The highest quantity of the particles in the distribution is at the diameter of about 2-6 μm (similar as presented in [8]). …”

Abstract. The use of biofuel has been increasing in Europe over the last years, and the reason for that is acceptable cost and the least negative impact on the environment. However, NOx and emissions of fine particulates are important, and biofuel is still a disadvantage compared to oil and natural gas fired systems. Usually, flue gas is filtered in multicyclones or fibre filters before discharge into the atmosphere. Yet, in the case of fine particulates, the filters of such type do not show high effectiveness, thus electrostatic precipitators are used. In this comparative study on biofuel (wood pellets), the collection efficiency of solid particles from a class 3 boiler (50 kW) and from a gasification unit (100 kW) was investigated. Although releases of solid particles from modern boilers are low, a combination of such a boiler with an electrostatic precipitator may reduce the releases of particles to the minimum, and the collection efficiency of the electrostatic precipitator obtained during the investigation was ~98-99%. There is a big difference in particle concentrations comparing the systems with flue gas and producer gas. As the working conditions in the test section with producer gas were harder, it led to lower efficiency of the electrostatic precipitator (~75%).

“…Similar results were obtained in [8] where particle concentrations from the modern 50 kW boilers fired by wood pellets vary in the range of ~11-40 mg/m 3 . So, particle concentrations in flue gas are about fourteen times less in comparison with producer gas.…”
