A method and apparatus for improving the efficiency and performance of a steam driven power plant wherein addition of steam handling equipment to an existing plant results in a surprising increase in plant performance. For Example, a gas turbine electrical generation system with heat recovery boiler may be installed along with a micro-jet high pressure and a low pressure mixer superheater. Depending upon plant characteristics, the existing moisture separator reheater (MSR) can be either augmented or done away with. The instant invention enables a reduction in T.sub.hot without a derating of the reactor unit, and improves efficiency of the plant's electrical conversion cycle. Coupled with this advantage is a possible extension of the plant's fuel cycle length due to an increased electrical conversion efficiency. The reduction in T.sub.hot further allows for a surprising extension of steam generator life. An additional advantage is the reduction in erosion/corrosion of secondary system components including turbine blades and diaphragms. The gas turbine generator used in the instant invention can also replace or augment existing peak or emergency power needs. Another benefit of the instant invention is the extension of plant life and the reduction of downtime due to refueling.

[ We claim:] [1.] A method for improving the operational characteristics of a steam driven power system utilizing low quality steam, comprising the steps of:(a) inserting a micro-jet mixer having a first inlet, second inlet and an outlet into a downstream portion of piping carrying the low quality steam from a steam generator, said micro-jet mixer further having a baffle located within the micro-jet mixer and having a pluality of micro-jets cut therein, said micro-jets extending through said baffle, said first inlet receiving said low quality steam on one side of said baffle; and(b) supplying high quality steam to said second inlet of said micro-jet mixer on an opposite side of said baffle, wherein(I) said high quality steam flows through said micro-jets mixing with said low quality steam causing said low quality steam to be superheated, thereby forming a high enthalpy mixed steam exiting said outlet of said micro-jet mixer.
