EFFECTOF N2 AND CO2 ON LOW HEATING VALUE LIMIT OF SURROGATE SYNGAS FROM MSW TO DRIVE RECIPROCAL SPARK IGNITION ENGINE

Abstract

Generally, Rankine cycle is used in MSW furnaces to recover the energy. The brake efficiency of Rankin cycle should be lower if the capacity is too small. Therefore, we try to use a reciprocal SI-ICE for the recovery in MSW furnace. The gas from MSW gasifier, MSW-syngas, has very low LHV. We developed a small gasifier for bio-syngas from wood. This bio-syngas is used to arrange a surrogate MSW-syngas. In this study, the surrogate MSW-syngas means the diluted bio-syngas with N2 or CO2. The experimental parameters are 1) N2 fraction, 2) CO2 fraction. The measured parameters are COV of IMEP.
