Coal, as the main fuel of the boiler, has a very significant effect on combustion characteristics and heat absorption in the boiler. Variations in coal specifications require regulation of boiler operating parameters to improve combustion efficiency and prevent failure of boiler tubes. The purpose of this study is to validate the simulation model on CFD software for 1x625 MWe capacity boiler according to the performance test parameters data. This simulation model, then, used to find out the temperature data on the rear pass boiler area and the temperature deviation between the left and right sides boiler. Then, the simulation output data compared with a measured operating parameter using statistical hypothesis testing methods. This study expectation is the difference between the simulation results and measured operating data is not significant. The simulation model can be used to obtain the right and left temperature deviation values and the rear pass temperature with different burner tilt angle and input coal calorific value in the further study then.
