This paper convenience power from examines the economic of producing electric some selected wastes by means of a two stage gasification-power generation system with a waste flowrate of 49 t/h. A comparison among RDF, RDF blended with waste oil, MSW from high income countries, bagasse and switchgrass shows that the last two give equivalent results, while the feeding, based on RDF, shows the worst results.

Abstract
This paper convenience power from examines the economic of producing electric some selected wastes by means of a two stage gasification-power generation system with a waste flowrate of 49 t/h. A comparison among RDF, RDF blended with waste oil, MSW from high income countries, bagasse and switchgrass shows that the last two give equivalent results, while the feeding, based on RDF, shows the worst results. As a consequence the sensitivity analysis is carried out by considering bagasse and MSW only. The analyses indicates that a variation of 60 Euro/t for investment cost, 0.04 Euro/ m(3)(STP) for oxygen gas and 7 Euro/t for the manpower cost influences only a little on the performance reached by the wastes. A depreciation value of 8% that ROI calculation indicates possible, allows at accumulating fresh capital for new investment. These data allow at concluding that the use of plants including the proposed two-stage reactor for producing electric power by using as a fuel wastes is promising and convenient.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
