SIMULATION OF 120MW INDUSTRIAL BOILER AT DESIGN CONDITION

Abstract

This paper presents an investigation of flow and combustion process in an oil fired, full scale furnace at design condition. The modeling is done using RNG turbulence model based commercial CFD-code FULENT. The simulations are executed in two stages with the effect of heat transfer to the furnace wall for full load and reduced load condition. The results of the simulations show that flow inside the furnace is highly swirling with intense combustion and comparing between full load and reduced load conditions, the temperature magnitude is not much different. On top of that, the predicted flow pattern and temperature distribution inside the furnace show reasonable qualitative agreement with practical observation.
