Many studies have reported DME as a potential candidate for
clean fuel to resolve the significant problems arising at present
such as the shortages of fossil fuels and the need for environmental
protection [1–3]. In a general power plant using a gas turbine, natural
gas containing as much as 85% or more methane (CH4) is used
as a primary fuel, while oil distillates are used as a back-up fuel.
However, market prices of such fuel are volatile. To cope with
the volatile market price of fuel, there is a need to develop a gas
turbine capable of employing diverse fuels for power plants. Particularly,
a new fuel, e.g. dimethyl ether (DME), and synthesis gas
produced from various raw materials such as natural gas, coal, biomass,
and wastes. by a chemical process are expected to be used
widely in the future in consideration of economical and technical
