Oil shale is the only organic natural source of energy in Jordan. Its reserves very huge that will be enough to meet Jordan’s requirements for more than 150 years. The objective of this study is to investigate the design and operating considerations for combustion of the Sultani oil shale, one of the Jordanian deposits, in a fluidized bed combustor (FBC). Thermal analysis and iterative calculations for the fluidized bed section in two types of thermal power cycles, air cycle, and supercharged boiler cycle, were performed at different operating conditions. The results of analyses and calculations have shown a number of charts for bed dimensions, heat removal, and steam-to-fuel ratios at different operating conditions and parameters. For example, as the operating bed pressure increases (2-10 atm), the bed height becomes much deeper and the bed volume is less than an atmospheric bed at 850°C, zero excess air and 350 m. FBC without in-bed heat exchanger requires a high quantity of excess air to maintain a constant bed temperature whilst with in-bed exchanger shows 63-69% heat removal at 8 atm pressure, 800 – 900°C temperature ranges and zero excess air.
