- Abstract:
- The tangentially fired utility boiler furnace is divided into several sections. The dynamic mathematical models for each section are presented. In the combustion zone, three-dimensional model is used, while for the upper sections, lumped parameter model is used instead. With the combination of different models, we can get detailed distributions of gas velocity, temperature, chemical species, heat flux, etc. in the furnace, but with less CPU time. The radiation through the interfaces of each section is considered. The furnace inlet boundary condition, which is exclusive for dynamic simulation, is also discussed. The dynamic response to the burner tilting up is simulated and discussed.
