The technical feasibility study of a thermoelectric power generation process consuming municipal solid
waste (MSW) is presented. Such fuel is fed into a bubbling fluidized bed boiler with combustion chamber
pressurized at 4 MPa. The flue gas is cleaned and injected into gas turbines while the produced steam at
10 MPa is diverted to a Rankine cycle. Costly and cumbersome cascade feeding systems are avoided by
feeding the particulate MSW as slurry into the pressurized combustion chamber. Therefore, the present
process dispenses fuel drying –– as usually required by more conventional processes—leading to substantial
savings on capital and operational costs. Additionally, the characteristics of bubbling fluidized bed
combustors allows for low pollutant emissions, which should also decrease the costs of further cleaning
in order to comply with required for emissions to environment. A comprehensive simulator (CeSFaMB) is
applied to predict the boiler operational behavior, while another (IPES) is employed to simulate the
power unit. The work shows the possibility of achieving power-generation efficiencies above the usually
found for such a low-grade fuel. Therefore, the present process is believed to be a good alternative for
discharging of waste while supplementing power for medium to large cities. The present work does
not include considerations on economics of the proposed process; however provides information for
future studies on such aspects.
