Abstract: To explore the effect of pulverized coal incident angle on volatilization, the ignition and combustion process of single particle pulverized coal in a McKenna burner was studied.The realizable k-ε model was used to simulate the movement of gas phase, the P1 model was used to simulate the radiation between particles and gas phase, and the discrete particle model (DPM) was used to simulate the movement of coal powder.The Chemical Percolation Devolatilization (CPD) model was used to simulate the pyrolysis process of pulverized coal.Combined with the volatile combustion and char combustion models, according to the results of coal powder elements and industrial analysis, the composition of volatiles was assumed, and the numerical simulation process was carried out based on FLUENT.The temperature measurement results under the experimental condition of methane/oxygen equivalent ratio 0.8 were used as the verification data of the calculation model.Five conditions of pulverized coal with different incident angles were simulated to obtain the variation process of temperature, velocity and volatile content with particle trajectory.By setting the UDF file to set the boundary temperature and velocity conditions in detail, the calculation error was reduced.At the same time, the grid independence was verified to avoid the error caused by the grid.The results show that whether the particles can pass through the high temperature region and maintain a longer residence time in the high temperature zone is an important factor affecting the volatilization and combustion of particles under the experimental conditions in this study.The temperature of most particles can reach more than 650 K after passing through the high temperature region and then volatilization and combustion occur at different heights.The co-existence of burning and unburnt particles observed during the experiment is also a proof.At the same time, the temperature and oxygen concentration distribution obtained by numerical simulation also effectively explain this phenomenon.The established model would lay a foundation for further study on ignition mechanism.
