The invention is an process that been added to "6" steam generators (once through steam generators) "OTSG", to improve the Efficiency of steam production with percentage of 3%. The basic elements that consist the process see the drawing in figure (1) A-Pre heater that is located between BFW pre heater unit and LBS unit to heat the feed water of the process by blow down water that exits from BFW pre heater unit to 203 C.° B-Pre heater to increase the temperature of the feed water of the process to 250 C.° C-Gas turbine that made by GE Company, in model of LM2000JDE, with Efficiency of 17.9 MW/h. D-(OT-HRSG) unit that is provided with Duct Burner. F-Tubular Air Pre heater. G-Stack to get rid of the exhaust gases. This PROCESS has been completed through three phases: The first phase: the process of heating 67500 Kg/hr of the feed water of the PROCESS via pre heater (A) and pre heater (B) to 250 C.° The second phase: the process of producing 67500 Kg/hr of steam through (OT-HRSG) unit, and producing of 17.9 electrical Megawatts from gas turbine to run the location. The third phase: the process of heating the intake combustion air to "6" steam generators (once through steam generators) "OTSG", through Pre heater Tubular to 160 C°. |
