BMWi-Project: FuelBand2 – Plant and feedstock optimisation for higher fuel flexibility of biomass furnaces
The project FuelBand2 develops a machine learning guard for slagging in biomass furnaces, that can be integrated in the system controll, to increase the flexibility of usable fuels.

The project addresses ash deposition („slagging and fouling“) in biomass-fired heat and power plants. The principle goal is to achieve a reduction of ash and slag contaminations and the development of an on-line detection system in order to facilitate suitable countermeasures. This potentially allows the utilization of higher shares of low-rank feedstock like forest residues.
The project aims at the evaluation of different fuel pre-treatment and plant operation strategies in order to reduce the ash deposition propensity in megawatt-scale combustion plants. These strategies will be implemented into an “online ash deposition system”, a framework based on realtime process data and additional sensors. Using a machine learning approach and regression modelling, empirical and experience-based plant control strategies will be applied and demonstrated for ash deposition mitigation in industrial-scale biomass combustion.
