Investigation of corrosion,aerosol- and particle formation in a wood fired power plant

During the combustion of wood, aerosols are released that can damage the power plant technology due to the mechanism of chlorine induced high-temperature corrosion. Thus, the aim of this investigation is to analyze the aerosols in a wood-fired cogeneration plant with regard to their corrosive properties. For these purposes two measurement methods were applied at the cogeneration plant in Schkolen. With one method particles have been extracted from the flue gas stream using a particulate sampling probe. To determine the number distribution of the particles an Electrical Low Pressure Impactor has been used to collect the particles and to sort them in terms of size. In addition, the collected particles have been examined both with respect to their morphology and with respect to their elementary composition by using a scanning electron microscope and the energy dispersive X-ray spectroscopy.     «
