Abstract:
This study examines the measurement data of forest chips’ quality gathered by using the continuous scanning measurement system. It was based on X-ray scanning of the moving forest-fuel stream from the whole load, measuring moisture content and impurities such as stones and other foreign matters. The x-ray measurement data contained moisture measurement values for load internal variation and load specific key figures. Values were gathered from two power plants during 2017-18 in Finland. Therefore, a seasonal raw material source based variation was possible to identify. The years under review were different in terms of weather conditions, which was reflected in the moisture data. A clear seasonal variation was noticeable, but the moisture content differences were relatively low between raw materials. By using continuous measurement, the problems with the representativeness of a sample can be avoided. The continuous measurement method is expected to reduce unwanted variation in fuel quality, when the fuel suppliers are able to react faster on the fuel-quality feedback. This study has demonstrated a fuel quality measurement and feedstock procurement approach that reduces carbon dioxide emissions in logistics and contributes to improved energy efficiency in heat and power production.
