Abstract

A gas turbine power plant having a heat recovery steam generator that generates steam at high and low pressures. The high pressure steam, which is superheated, is partially expanded in a steam turbine, thereby producing shaft power. All of the partially expanded steam is then combined with low pressure steam. The combined steam flow is superheated and then injected into the combustor of the gas turbine to increase power output and reduce NOx.
