Gas turbine combined cycle design program to create cycle heat balance and physical equipment needed to realize it

GT PRO automates the process of designing a combined cycle or gas turbine cogeneration plant.  GT PRO is particularly effective for creating new designs and finding their optimal configuration and design parameters.  The user inputs design criteria and assumptions and the program computes heat and mass balance, system performance, and component sizing.  The scope and level of detail in GT PRO has been continuously growing since 1988, to the point that the 2008 version has over 3000 user-adjustable inputs.  Most key inputs are automatically created by intelligent design procedures that help the user identify the best design with minimal time and effort, while allowing the flexibility to make any changes or adjustments.  GT PRO is truly easy to use, typically requiring only a few minutes to create a new plant design.  It normally computes a heat balance and simultaneously designs the required equipment in under five seconds.  When run in conjunction with the optional PEACE module, the programs provide extensive engineering and cost estimation details.


The variety of gas turbine based power plant configurations you can design in GT PRO is virtually endless.  From gas turbines in simple cycle, to engines exhausting into waste heat recovery boilers for process steam, optionally including condensing, non-condensing, or reheat steam turbines, with any sort of cooling system, are all easily accommodated in GT PRO.  The following is a small sampling of the variety of plants that you can generate in a matter of minutes.  While only an overview graphic is presented to describe each case, the program provides from 50 to over 100 outputs consisting of well-organized overview summary reports, detailed equipment descriptions, and informative graphical displays.
