Lo scenario
A combined cycle power plant uses an HRSG and vacuum deaerator to condition condensate and supply boiler feedwater. The P&ID shows condensate pumping, deaerator level and pressure control, and feedwater flow control to the HRSG.
Cosa contiene questo disegno
Leggi le decisioni che ne stanno alla base.
01
Use vessel_h D-101 as horizontal vacuum deaerator with top condensate inlet and bottom feedwater outlet.
02
Add separate diaphragm control valves V-101, V-102, V-103 for feedwater flow, deaerator steam pressure, and deaerator level.
03
Wire transmitters FT/LT/PT to shared controllers FIC/LIC/PIC with electric signals and pneumatic actuator lines.
Reuse for HRSG or conventional boiler feedwater systems needing vacuum deaeration and three-element control.
