Straight vegetable oil use in Micro-Gas Turbines: System adaptation and testing

► The possibility to feed a Micro Gas Turbine with Straight Vegetable Oil (SVO) has been investigated. ► Correlative analysis and CFD were used to model the effect of SVO characteristics on atomization and evaporation. ► Minor modifications to a the commercial MGT were adopted. ► Measured power output and specific fuel consumption were close to standard fuel, taking into account the LHV of SVO. ► Emissions were higher than for standard fossil fuel but strongly affected by SVO temperature.
