The increasing of municipal solid wastes (MSW) in Bandung needs an effective and unconventional solution. Burning of MSW in an incinerator is an effective solution to handle that problem since it can reduce the volume of MSW in a relatively short time. The hot gas produced from the combustion of MSW then is used to generate steam and produce electricity. This waste to energy (WTE) facility is planed to be applied in Babakan, Bandung regency. The objective of this study is to analyze the combustion characteristics of the Bandung’s MSW and to obtain the main geometry of the steam generator. The combustion characteristics of the MSW in Bandung regency are obtained by using the data of combustion characteristics of the MSW in Bandung city. The combustion characteristics of the MSW are obtained by summing the multiplication of experimental data of the MSW per component with its component’s percentage. The elemental composition of MSW with 40% of moisture content are 19.38% carbon, 2.63% hydrogen, 0.1% sulfur, 0.6% nitrogen, 16.8% oxygen and 0.49% of chlorine, with its Lower Heating Value (LHV)1557,54 kcal/kg. Design process is conducted by using Cycle Tempo and Firecad software. The results from software then verified by hand calculation to obtain accurate results and to fulfill the design requirement of the MSW’s incinerator. From the analysis, the main geometries of steam generator furnace are 19 m in height, 1.66 m in width and 1.86 m in depth. The results of this study also obtain the main geometry of superheater, boilerbank, air heater and condenser.
