1WHAT IS GT PRO? Thermoflow Inc. GT PRO is a highly automated system design tool – a heat balanceprogram specifically intended for design of gas turbine combinedcycle power plants and cogeneration systems.Use GT PRO to explore and design combined cycles, cogeneration systems,and simple cycle gas turbine power plants.In combination with PEACE (Plant Engineering and Cost Estimator), GT PROprovides engineering details and cost estimation.GT PRO performs design-point calculations only – use GT MASTER forsimulations of part loads or other off-design conditions.
2What does PEACE add to GT PRO? What is PEACE?PEACE is Thermoflow’s Plant Engineering And Cost Estimator, anadditional tool that works in conjunction with Thermoflow’s heat balancedesign and simulation programs.What does PEACE add to GT PRO?PEACE brings regional costs, engineering details, and concerns beyondthe heat balance performance into a comprehensive description of the plant.PEACE provides graphic and tabular information about size, weight,and cost of plant equipment.PEACE produces a detailed total plant cost estimate.PEACE provides a simple pro forma financial projection to estimatecash flows, return on investment, and break-even power cost.PEACE can be used to impose more detailed hardware effects uponheat balance simulations, particularly piping and pump hardware details.
3Inputs – General Arrangement GT PROInputs – General ArrangementThe Navigator column displays the major inputtopics. Topics in GT PRO are arrangedvertically, and follow a hierarchy, progressingfrom top to bottom. Selections made in anupper (earlier) topic will condition the selectionsavailable in lower (later) topics.Tabs are used as necessary to subdividetopics; green tabs include PEACE inputsEvery entry box has been initialized with areasonable value. You never have to fill anempty box. Instead you edit just those thatare of concern to you, trusting the others tohave been logically selected.
4The program opens to the New Session topic GT PROThe program opens to the New Session topicSelect to begin a new design or to revise an existing one.Make selections in each of thepanels at left. These informthe Setup Wizard used toinitialize many of the inputs.Click on Start Design to continue.
5At the Start Design topic... GT PROAt the Start Design topic...Refine the plant configuration by selecting thenumber of pressures at which your HRSG willproduce steam, and indicating how that steamwill be used.Click any other topic to move on.Edit entries in any order youchoose, then click Compute.The internal hierarchy for order ofthe inputs (top to bottom) willintervene only as necessary forconsistency.
6At the Plant Criteria topic... GT PROAt the Plant Criteria topic...Of the several Tabs within this topic, the Sitetab is of greatest importance to the thermal design.Select the cooling system type of your choice.The figure illustrates and confirms your selection.
7Visiting the Regional Costs tab... GT PROVisiting the Regional Costs tab...Click on any of the domestic (US) or international locationsto view and then initialize values for Cost Multipliers, whichcondition the GT PRO / PEACE cost estimation relativeto the reference, generic US cost estimate.
8At the GT Selection topic ... GT PROAt the GT Selection topic ...Select a gas turbine from over 285 available engines,including all major vendors.Tabulated ratings are at ISO conditions, with noinlet or exhaust pressure losses. Notes in the Guidancewindow add further description.
9Within the GT Inputs topic ... GT PROWithin the GT Inputs topic ...You can:Select to inject water or steam.Reselect fuel (default is methane).Incorporate inlet air chilling, evaporativecooling, fogging or heating.Adjust model performance.Revise inlet and exhaust draft losses.Connect any GT heat rejection tosteam cycle.
10At the ST-HRSG topic... This is the place where main steam conditions GT PROAt the ST-HRSG topic...This is the place where main steam conditionsand process export streams can be defined. Asalways, initial values are in place. Turbine inletconditions are initialized logically by the SetupWizard in accord with your initial settings.
11HRSG Inputs The Main Inputs tab lets you set GT PROHRSG InputsThe Main Inputs tab lets you setconditions of the duct burner, ifused, and other key designparameters. 2nd and 3rd tabsprovide more user control if desired,but can be confidently left to thewell-reasoned defaults.
12Moving on to the Cooling System... GT PROMoving on to the Cooling System...Click on the Design Method selector if you wish to exert morecontrol upon the cooling system’s design parameters. Bydefault, parameters will be set automatically, in accord with theambient conditions and your Cost/Efficiency setting.
13Looking at the ST Inputs topic... GT PROLooking at the ST Inputs topic...Process streams supplied solely by extractionfrom the steam turbine are defined here.Other details of the turbine can be editedin the underlying tabs.
14GT PRO Outputs Three categories of outputs – Text, Graphics, and PEACE, are provided, each with multiple tabsto help you quickly find the results you need.The last four buttons let you:(1) Produce a series of related designs begun with the current file.(2) Begin simulation of the present design, under differentconditions, using GT MASTER.(3) Import the model using THERMOFLEX.(4) Produce related designs using the E-LINK Microsoft Excel macro.
15GT PRO Text Output Select from the Tabs above to view the category of text outputof interest.
16GT PROGT PRO Graphics OutputThis overview displays gross and net electrical output, heatrate, and fuel energy input. Note also the many othergraphic displays to be selected from the tabs above.
17Graphics – Cycle Flow Schematic GT PROGraphics – Cycle Flow SchematicThis figure illustrates all the significant flows inthe plant. Units are identified in the legend below.
18Graphics – HRSG Temperature Profile GT PROGraphics – HRSG Temperature ProfileThe temperature profileillustrates how effectivelythe exhaust gas energy isrecovered by the HRSG.Clicking anywhere on thediagram causes the data to bedisplayed in tabular form.
19Graphics – Psychrometric Chart GT PROGraphics – Psychrometric ChartShown here for a combination wet-dry cooling tower, thisdiagram shows the conditions of the humid air passingthrough and mixing after the wet and dry segments ofcooling tower.
