Abstract
Stricter regulations for nitrogen oxide emissions require an aftertreatment of exhaust gases from biomass combustion plants, such as biogas cogeneration plants. For this reason, SCR systems are used in these applications and their functionality should permanently be monitored during operation to ensure sufficient efficiency at lowest operating costs. The radio-frequency-based state diagnosis of catalytic converters is suitable for this purpose and has already been extensively tested for three-way catalytic converters (TWC) or NOx storage catalysts (LNT) in the automotive sector.
