Characterization of diesel engines fueled by dual fuel syngas gasification refused derived fuel (RDF) and dexlite
Keywords:
Diesel engine, refused derived fuel, dexliteAbstract
The increasing energy demand is accompanied by a decrease in fossil energy, it is necessary to develop alternative fuels. Refuse derived fuel (RDF) which is a processed product from urban solid waste (MSW) can be used as alternative energy using gasification technology. The application of the three-stage gasification technology made from RDF is able to produce syngas with a tar content below 100 mg/Nm3, so that it can be used in internal combustion engines with dual fuel diesel technology. This research was conducted experimentally with the aim of knowing the performance characteristics of a diesel engine using duel fuel syngas as a result of gasification of RDF and dexlite. The test was carried out with a constant rotation of the diesel engine at 2200 RPM with varying electrical loads starting from 500 Watts to 7000 Watts with 500 watt intervals. Blower is added to supply combustion air with mass flow rate variation: 0.0068 kg/s; 0.0073 kg/s; 0.0078 kg/s; 0.0083 kg/s; and 0.0088 kg/s. The research data measured the amount of dexlite that can be substituted with syngas, the specific value of fuel consumption, thermal efficiency, and engine operating temperature. The test results obtained that the dual-fuel system can substitute the highest dexlite of 43.45%, The results of this study can be used as a reference for the development of the use of dual fuel engines.
