This tab is to select and input the design conditions of Design Heat Balance.
When User selects or inputs here, the same is automatically reflected in the other tab that has same selection or input. Vice-versa works automatically, too.
For example, if User selects Reheat Turbine at "Cycle Type" combo box in "Start" tab, reheat turbine cycle graphic is automatically drawn in "Graphic" tab. If User inputs Condenser pressure in "Steam" tab, the condenser pressure in this "Graphic" tab automatically changes accordingly. Vice-versa is also true.
The graphic below is automatically made by clicking "Smart Run & Add to List" button after selecting "850 MW Class Reheat Advanced Ultra-Supercritical" in "ENGSOFT List" combo box of "Start" tab.
Power given, Flow given option button
To select whether Design Heat Balance is calculated by Power given or Flow given.
If User selects "Power given", then the background color of "Gen. Output" text box changes to green and activated for input. If "Flow given" selected, then the background color of the (HP) turbine inlet flow text box changes to green and activated for input.
This selection is automatically reflected to the "Calculation" combo box of "Steam" tab.
Turbine Inlet combo box
To select the second property input for (HP) turbine inlet steam. There are three options, i.e. "Temperature", "Dryness" or "Enthalpy". According to the selection, the Unit character of the second inlet steam property changes to "T"(Temperature), "X"(Dryness) or "H"(Enthalpy) respectively.
This selection is automatically reflected to the second "Turbine Inlet" combo box of "Steam" tab.
Selection of Turbine Efficiency Calculation Method
The turbine efficiency calculation method can be selected in "Cycle Type" combo box of "Start" tab.
If User selects a list item with "Efficiency by User" description, turbine efficiency should be input by User and the background colors of turbine efficiency text boxes changes to green and activated for input. If not, turbine efficiency shall be calculated by software automatically and the background colors of turbine efficiency text boxes changes to green and de-activated.
Selection of Feed Water Heater Input Method
Feed water heater design data input method can be selected by checking of "P Tbn Ext" Input check box of "Start" tab or "FW Heaters" tab.
If User checks the check box, the background colors of "P Tbn Ext" text boxes of this tab changes to light green and be activated for input. In the other case, the background colors of feed water outlet temperature text boxes changes to light green for input.
Feed Water Heater Type combo boxes
To select type of the feed water heater just above the combo box.
This selection is automatically reflected to "FW Heaters" tab. Vise-versa works automatically, too.
