Lean fuel intake gas turbine

Lean fuel intake gas turbine

The present invention relates to a lean fuel intake gas turbine which is capable of stable operation avoiding an accidental fire at a catalytic combustor and an explosion in a compressor even when there is a change in fuel concentration. In a lean fuel intake gas turbine (GT) which uses a mixed gas...

description The present invention relates to a lean fuel intake gas turbine which is capable of stable operation avoiding an accidental fire at a catalytic combustor and an explosion in a compressor even when there is a change in fuel concentration. In a lean fuel intake gas turbine (GT) which uses a mixed gas below a combustible concentration limit in which two types of fuel gases with different fuel concentrations are mixed with each other as a working gas (G1), a first mixer (21) generates a first mixed gas by mixing the first fuel gas which has the lower fuel concentration with the second fuel gas which has the higher fuel concentration, from the fuel gases having differing concentrations. A second mixer (23) generates a secondary mixed gas which is the working gas by mixing the first mixed gas with the second fuel gas.
