Topic

The theme of the project is to increase the energy efficiency of biomass power plants by the technical application of a biofuel catalogue (BBC) developed by the applicants. The biomass catalogue should to be used as a general instrument to predict the effect of different biofuels on the formation of slags in the combustion chamber and deposits in the convective boiler area. It also provides the basis for fuel-based and process-oriented optimization options for BHP plants.

Aims

The scientific and technical work objectives are as follows:

• Validation of the procedure for the preparation of the BBC and the transferability of the technical application of the BBC to BMHP plants, which are equipped with different process technologies
• Simulation of the predicted chemical-mineralogical reactions for the formation of slags and deposits in the laboratory and technical scale for the combustion of waste wood and other selected biogenic residues and waste materials
• Development of optimization possibilities for BMHP plants
• Development of measures for an increased use of technically difficult biofuels
