Zusammenfassung:	A method for starting and operating a NMHC fueled gas turbine combined cycle power plant 10 includes injecting gaseous NMHC fuel into a gaseous NMHC fuel treatment system 206, injecting at least one of auxiliary steam 222, HRSG steam 226, or HRSG water 224 into the gaseous NMHC fuel treatment system, and mixing the at least one of auxiliary steam, HRSG steam, or HRSG water with the gaseous NMHC fuel in the NMHC fuel treatment system 206 to form a gaseous NMHC fuel mixture. The method further includes injecting the gaseous NMHC fuel mixture into a gaseous NMHC fuel distribution system 208, and providing the gaseous NMHC fuel mixture through the gaseous NMHC fuel distribution system to a combustor 14 of the NMHC fueled gas turbine.
