Abstract:
Wood combustion in small scale boilers is widely used for domestic heating. The boiler capacity, combustion conditions, fuel quality, etc. strongly influence on particle emissions from the facility. However, fine particles, which are associated with various diseases, still contribute significantly to the PM-burden in many cities. The purpose of the current work is the development of effective methods and equipment for control fine particle emissions from small scale wood combustion boilers. The first part of the study is devoted to long-term experimental study of the influence of combustion conditions in a 100 kW wood-chips boiler on the fine particle emissions and exhaust gas composition. The second part of the study is related to the development and long-term experimental study of the novel form electrostatic precipitator (ESP) for small scale biomass combustion. The space-charge ESP consists on the direct current (DC) negative corona discharge ionizer and collectors equipped with grounded brush-electrodes. In the ESP charged particles are precipitated under the influence of space charge effects. The attention of the discussion is concentrated on the parameters which influence on the ESP operation efficiency and stability.
