Abstract:

Micro gas turbines units are reliable and versatile units for distributed combined heat and power production (CHP). Compared to internal combustion engines, CHP units based on micro gas turbines offer several advantages, among which the compactness, the high power­to­weight ratio, lower pollutant emissions and lower maintenance costs. Depending on the specific type of gas turbine, also fuel flexibility could be higher than engines. This study report on the preliminary results obtained with a small size (25 kWe) Garrett GTP 30­67, liquid fuel micro gas turbine, which was adapted to run on alternative first generation biofuels, such as vegetable oil and biodiesel and pyrolysis oil. An in­house test bench for biofuel testing, capable of accommodating the micro gas turbine, was designed, engineered and built. In this paper, results from experimental measurement on the micro gas turbine are presented. Micro gas turbine performance (e.g specific fuel consumption, heat rate) were monitored and main exhaust emissions, i.e. CO and NOx, measured between idle and full load when feeding biodiesel, vegetable oil or pyrolysis oil to the engine; results were then collated with literature and accommodated with respect to environmental pressure and temperature to standard testing conditions (ISO/ASTM). Preliminary advice on engine operation with pyrolysis oil will also be given.
