Abstract:
Biomass is an important resource and plays a key role within the ambitious greenhouse gas reduction targets. To comply with the strict emission thresholds as well as the requirements on biomass boiler efficiency within the EU legal framework, an affordable and simple near-infrared (NIR) retrofit solution for online fuel characterization was developed and tested to enable optimal boiler settings with respect to actual characteristics of the used fuel assortments. Thus, a cost-effective online NIR spectroscopy device (SCiOTM, Consumer Physics) with investment costs <1000 € was applied. Chemometric models developed with partial least square regression for the prediction of moisture, nitrogen, ash and potassium content, as well as the net calorific value were used and validated. The NIR retrofit solution was successfully coupled to the fuel feeding system of a commercially available small-scale biomass boiler for automatic operation. The results showed good predicted values for the biomass properties in comparison to the lab analysis. The NIR retrofit solution is therefore currently tested in the field during operation of fixed-bed combustion and gasification plants with a capacity of up to 40 MW.
