Numerical Study on the Devolatilization models of Pulverized Coal in DTF
DTF 내 미분탄 휘발화 모델에 관한 수치적 연구
Abstract
In order to evaluate the devolatilization models of pulverized coal, various devolatilization models are examined for the numerical analysis of Drop Tube Furnace.The results of analysis are compared with the experimental results. A numerical study was conducted to explore the sensitivities of the predictions to variation of the model parameters. It helps to elucidate the source of the discrepancies. Three different wall temperature conditions of the DTF, 1100, 1300 and
