Abstract

Abstract: Non-petroleum-based fuels help in mitigating climate change by reducing the emission. Many studies on the emission characteristics for the alternate fuel dimethyl ether (DME), resulted in a significant reduction in NOx, SOx, and particulate matter. Due to the potential impact of the use of DME, a need for an Alternate fuel powered Micro gas turbine power plant for high altitude flight was investigated. The potential energy of DME reacting with oxygen was calculated in the temperature range 800-1350 K at the total pressure exhibited on combustion chamber similar to that of high altitude flight. Multichannel ab-initio and RRKM calculation were performed on the DME combustion reaction in the presence of air C2 H6 O+O2 +N2 →CO2 +H2 O+N2. The computed energy value obtained at low pressure was used to study the thermodynamic cycle of a 6kW micro gas turbine power plant for the use of power generation at high altitude flight system. The resulting energy flow model obtained is significant to understand the system performance and efficiency optimization.
