摘要:In order to accurately calculate the combustion rate of coal powder in the furnace, starting from the study of the combustion mechanism of coal particles, the combustion process of coal powder in the most complex burner area in the furnace is studied, and the combustion process of volatile points and Coke in coal powder is reasonably simplified. A one-dimensional macroscopic model of pulverized coal combustion along the Gaodufangxiang is established. The model takes into account the change of oxygen content in the combustion process of pulverized coal and is based on an equal density model of combustion of individual pulverized coal particles. The combustion process of pulverized coal reflects the whole process of pulverized coal combustion, and the formula for calculating the combustion rate of pulverized coal in furnace is deduced, which satisfies the requirement of real-time simulation calculation. The simulation results agree with the measured data and the existing literature, and the results are analyzed.
