An efficiency study on the urban solid waste gasification process for electric power generation

This work analyzed the efficiency of the gasification process applied in Urban Solid Waste (USW), since tests carried out in a pilot plant, as a way of studying the feasibility of applying the process in the production of a gas for burning in a boiler and generation of electricity, on a steam turbine and generator system, on commercial scale. The results indicated the feasibility of the process both in the high conversion efficiency of the Residue Derived Fuel (RDF) into gas as in obtaining a gas with burning and energy generation favorable characteristics. A second analysis evaluated the potential of electricity generation in a Rankine cycle steam turbine demonstrating an estimated generation able not only to supply energy for the whole plant, from USW processing to the fuel gas burning, but also for exporting to the energy grid.
