Increasingly scarce energy resources makes us have to keep working to find new energy sources and renewable. Indonesia as the largest palm oil producer in the world has a source of very large biomass from oil palm plantations. Oil palm <br /> <br /> <br /> empty bunches (Empty Fruit Bunch) is one of the biomass that has sufficient heating value potential for use as fuel at a power plant fueled biomass. <br /> <br /> <br /> This study aims to get initial design of a steam power plant with its EFB fuel combustion simulation. The design configuration is done by CycleTempo software, the main geometry of the furnace, superheater, boilerbank and airheater done by Firecad software, combustion simulation is done by using a combination of Flic and Fluent software. <br /> <br /> <br /> The furnace design based on the condition with 20% EFB moisture content and 70% excess air. The primary air of combustion is assumed at 70% and secondary air is 30%. Fuel composition as result from prediction are 33,29% carbon, 4,07% hydrogen, 34,57% oksygen, 0,4% nitrogen, 0,16% sulphur, moisture 20% and 7,5% of ash and it’s Lower Heating Value (LHV) is 10854,8kJ/kg. Flue gas from boiler is used for air heater. From software simulation we get 2940 kW electric power with 3865,22 kg/hr EFB input. The maksimum temperature in grate area is 2210 K and at superheater area in the range 905 – 1340 K. It also viewed <br /> <br /> <br /> the influence of several parameters such as particle diameter, shape factor, speed of bed and moisture content against the contours of temperature in the furnace <br /> <br /> <br /> especially in superheater area.
