Abstract

The aim of the project is to develop an advanced CFD model that can predict the combustion behaviour of syngas at elevated pressure. Of key importance is to be able to predict the influence from impurities in the syngas on flue gas composition (including aerosols), thereby making it possible to optimise the syngas cleaning based on the requirements from the technical application, e.g. an industrial gas turbine or an industrial heating process. The model is based on the Flamelet Generated Manifold concept using a RANS approach. The flame advancement is done with the Coherent Flame model while turbulence is modeled with the k-w SST model. Model validation will be based on literature data from the TECFLAM project and on own experiments with syngas in the CECOST burner (operated by Lund University).
