(Scientific tools for fuel characterization for clean and efficient biomass combustion)

This project includes some of the main actors in the field of biomass combustion from Denmark, Finland, Norway and Austria. The research covers experimentally based model development, fuel characterization and fuel conversion for a wide range of “difficult-to-burn” feedstocks in technologies ranging from small scale grate fired units over large scale grate and fluidized bed combustors to bio dust applications in large centralized combined heat and power plants.


The overall goal of the project is to optimize plant designs with respect to high energy efficiency, low emissions and reduced operational problems (slagging, ash deposition) for biomass fuels and fuel mixtures.


There has been a persistent focus on the reduction of air pollutants and greenhouse gases and growing and fluctuating energy prices. This has resulted in an increasing use of various biomass based fuels for electricity production and a growing importance of fuel flexibility. 

Some biomass fuels are characterized by higher ash content including alkali metals, low first ash melting point and elevated content of N, S and Cl, which may result in problems regarding increasing slagging, ash deposition and formation of fine particulate matter and an increasing amount of NOx, SO2 and HCl emissions. 

The Project

The SciToBiCom project focuses on nitrogen chemistry and NOx formation and fuel and ash chemistry for various combustion technologies and fuels.

 This project was completed in 2013.
