Waste Plastic oil used as an Alternative fuel for Aero Diesel Engines: an Analysis 2019-01-1896

The use of plastics and its production has seen a significant increase in recent years and accordingly the amount of plastic waste that gets accumulated in the environment has increased to an alarming level. Since plastics are primarily a petroleum based product, this increase in demand for plastics has to certain extent reduced the availability of petroleum as a non-renewable fossil fuel. One of the options to reduce the pollution due to waste plastic and create an alternate source of energy is to recycle the plastic waste by converting them into valuable energy resource. In this regard, oil derived by pyrolysis of waste plastics becomes a promising one to be used as a resource of aviation fuel. The current study analyses the oil derived by pyrolysis of waste plastics to be used in aero diesel engines. The study focusses on the use of waste plastic oil with diesel blend and compared its performance with diesel. The thermodynamic performance of the plastic oil blended with 10, 20, 30, 40, and 50% diesel are examined and related with diesel fuel operation. In addition the effect of several thermodynamic parameters on total and component level exergy destruction has been discussed. It’s reported that the aero diesel engine using the blend of waste plastic oil with diesel shows an excellent driveability and efficiency. The brake thermal efficiency and exergy efficiency of aero engine is increased and the total exergy of destruction is reduced by the use of waste plastic oil as compared to diesel fuel operation.
