Engineering Model for Prediction of Waste Incineration in a Dump Combustor

摘要

An engineering model that can be used to obtain predictions of axial distributions of temperature and species concentrations in complex flows has been formulated and applied to waste incineration in a dump combustor. The model incorporates mean convection and molecular diffusion in a quasi-one dimensional sense and uses a stochastic model to approximate the effects of turbulent convection. The inputs to the model are extracted from experimental data and results of Large Eddy Simulations (LES). Comparisons of waste consumption rates and pollutant formation in the dump combustor with experimental data show that the model can capture the correct trends and achieve fairly good quantitative agreement. Further, the model does not use any ad-hoc constants that need to be calibrated or tuned.
