    Abstract

    Coal blending is the method to get good characteristic of blended coal for power plant. Ash fusion temperature (AFT) is parameter target in blended coal. AFT are parameter that having influence formation of slaging and fouling on heat transfer system of boiler. Beside using laboratory analysis, this study use simulation for prediction coal ash fusion temperature of blended coal. The name simulation are coal blending simulation. Coal blending simulation is a practically and quickly prosedur to get coal ash fusion temperature of blended coal without doing laboratory analysis. 13 coal samples as parent coals from South Sumatera, Indonesia were analyzed at Energy Fosil Laboratory B2TE-BPPT and including 21 blended coal. The simulation formula is taken away from Chen, W. M (China). Chen, W.M use multiple linier regression to predict coal ash fusion temperatures especialy coal ash softening temperature. The result of comparing AFT value between laboratory analysis and statical model/modelling are the maximum fractional error is 0.49, the minimum error is 0.01 and the average error is 0.05. Key Word: coal blending, simulation, laboratory analysis, modelling.
