Abstract

This paper presents the results of a major R&D program with the objective to develop CFD based tools to assess the impact of biomass co-firing in suspension fired pulverized coal power plants. The models have been developed through a series of Danish research projects with the overall objective to collect results from fundamental research and make it operational in boiler design through implementation in a Computational Fluid Dynamics based simulation tool. This paper summarizes the developments in modeling of; particle motion, particle conversion, ash deposition on heat transfer surfaces, and NOx emissions. Results are presented for a Danish full-scale boiler that is currently co-firing biomass with coal on a commercial basis.
