PROBLEM TO BE SOLVED: To utilize oxygen enriched air other than pure oxygen or air as a fuel burning oxidant, without a large scale facility in the upstream of a steam turbine or a generator, and producing exhaust loss. SOLUTION: This powering system is equipped with; a fuel supply system 11 for supplying fuel, an oxidant supply system 13 for fuel burning oxidant composed of air, oxygen enriched air, or pure oxygen, a combustor 15 for making high-temperature combustion gas having a main component of superheated steam, by mixedly burning steam, fuel fed from the system 11, and a fuel burning oxidant fed from the system 13, a turbine 17 having a drive source of high- temperature combustion gas from the combustor 15, and a generator 18. Consequently not only power generation output can be increased by making steam have high temperature through utilizing a few fuel and a burning oxidant, and be working fluid, but also a turbine and a power generating system for generating power at high efficiency can be constituted.
