- W4285348766 abstract "To save on coal consumption in PLTU (Steam Power Plant), it is necessary to increase boiler efficiency. The factors that can affect boiler efficiency include: flue gas temperature, fuel specification, excess air, ambient temperature, radiation and convection losses. By changing the value of excess air in this case the percentage of oxygen (4% to 4.5%) will affect the efficiency of the boiler. Changing the value of excess air also results in a change in the electrical power used by the auxiliary system in the boiler. Calculation of boiler efficiency with the direct method by testing 2 times on each oxygen percentage value of 4% and 4.5. Efficiency increased 0.94%, from 80.76% to 81.7% in test 1 and increased 1.02%, from 90.81% to 91.83% in test II. The power usage increased by 27.959 Kw in the 1st test and increased to 26.663 Kw in the test II.Kata kunci: Boiler, efficiency, excess air, PLTU" @default.
