Abstract:
Moderate or intense low-oxygen dilution offers a great opportunity to reduce harmful pollutants. Besides its wide application for gaseous and liquid combustion, it is also of interest for solid fuels, such as coal. In contrast to gaseous MILD combustion, there is no general agreement on the criteria to (a-priori) analyze and characterize MILD combustion. Therefore, we investigate several suggested criteria based on a well-known coal MILD combustion furnace. The conclusions derived from the different criteria are compared in order to assess their applicability. Additionally, we simulate the furnace with the open-source CFD tool OpenFOAM to calculate the Damköhler number in the overall domain of the furnace.
