Abstract: Fuel and firing system purposely to deliver light fuel oil or coal as one of the primary elements of fuel in an ideal condition for combustion to take place in the boiler combustion chamber. Milling system in coal power plant purposely to process the raw coal to become as pulverise fuel before enter to the boiler furnace. Pulverise fuel enter to the boiler furnace through pulverise coal pipe (PC) which attached to the boiler. The different mill has different PC pipe corners, and with different length and high level. This case indicates and measures the changes of boiler parameters due to different mill in service. The results show, the highest mill in service not affected to the boiler parameters such as reheater metal temperature, main steam temperature and boiler flue gas outlet and others boiler parameters during combustion process. The results also presented thru empirical data where it showed that the distribution of pressure, temperature, velocity at the boiler is equalized. The operating of mill parameters during the research carried out is monitor closely to avoid explosion to the mill. Besides that, the size of the PF as a main fuel is measured to ensure complete combustion in the boiler furnace. The results indicate the optimum arrangement of the mill operation with minimum boiler parameters affects.
