ABSTRACT:
A process and equipment for generating useful power comprising a special split stream heat recovery boiler 108 in combination with a gas turbine 20 and a steam turbine 80 to form a combined cycle. A steam-injected gas turbine 20 and alternately a condensing steam turbine 116 may be utilized. A topping high temperature and high pressure topping steam turbine 80 optionally may be included. Chemical heat recuperation via natural gas reformation may be incorporated within the boiler 108 to increase cycle efficiency further and to lower NOx formation without excess CO. The heat recovery boiler 206 yields increased efficiency and power output heretofore unexpected for the combined cycle compared to conventional combined cycle equipment.
