C. M. Raguraman, A. Ragupathy, L. Sivakumar

Abstract :

A pre–heating vaporization technology of coal water slurry was developed to increase the efficiency of coal gasification with reduction of oxygen consumption. The heat transfer rate of coal slurry in agitated vessel will depend on the operational parameters of the experiment such as stirrer speed, stirrer location, D/d ratio and coal–water ratio. The planned experiments are conducted in the agitated vessel and the signal–to–noise ratios are computed to determine the optimum parameters. The percentage contribution of each factor is validated by analysis of variance (ANOVA) technique. Multiple regression analysis (MRA) is conducted using statistical package for Minitab–15 software and the mathematical model is build to predict the heat transfer rate of coal water slurry for any given conditions.
