Heat Exchange Element To Model As A Feedwater Heater With Desuperheating & Drain Cooling Sections

[Joe Baranski]

How to Model a standard Heat Exchanger element to force Steam Desuperheating and Drain Cooling Sections to assure sub-cooled condensate leaving (single phase liquid flow)?

[Luca Finardi]

Hi Joe,

if you want to include your feedwater heater in a thermodynamic model, you can simulate it with a cooler and an heater coupled through a specification block. You can either model as a single couple and set directly the temperature difference on the steam side or as two coupled cooler-heater if you want to have control of the degree of subcooling on the drain side.
See the attached model with both options.

Hope it helps.
