Abstract:
1. A gas turbine system useful with a first fuel at full load and a second fuel to achieve an improved emission behavior, with the second fuel having a richer mix of higher-value hydrocarbons with 2 or more carbon atoms per molecule than said first fuel, the system comprising: a gas turbine having a compressor, at least one combustion chamber, and at least one turbine; at least one fuel source; a main fuel feeding line fluidly communicating the at least one fuel source to at least one of said at least one combustion chamber; means for controlling change of the composition of the fuel flowing though the main fuel feeding line; a reservoir containing higher-value hydrocarbons; wherein the means for controlling comprises an auxiliary fuel feeding line configured and arranged to discharge into the main fuel feeding line, the auxiliary fuel feeding line being fluidly connected to the reservoir; wherein the higher-value hydrocarbon containing reservoir comprises a liquid gas storage tank; and an evaporator arranged in the auxiliary fuel feeding line.
