The main fuel in Suralaya PLTU uses coal. Coal consumption as fuel must be in accordance with the boiler specification. The Company difference who supply coal to Suralaya PLTU that is cause difference in qualities of Coal. So that to comply machine specification, coal treated by blending method. Blending method has to affect the efficiency of the boiler. This thesis research has effect of coal quality and Pollutant rate to boiler efficiency value. The calculation of boiler efficiency based on the heatloss method. Specific fuel consumption has to calcualate and pollutants rate as comparison with the boiler efficiency. The results expected in this study are coal calorific value directly proportional to boiler efficiency and specific coal consumption. Then Quality mix coal is directly proportional to boiler efficiency and inversely proportional to specific fuel consumption. Indicator in coal blending is not only based calorific value. However, in each parameter in the coal contents. The boiler efficiency value of mix coal is influenced by boiler performanmce and environmental factors. The boiler efficiency value is directly proportional to SO2 and NO2, and the value of total particulates is not influenced by the efficiency value. However, total particulates are influenced by the coal quality and boiler performance.} }
