The scenario
University campus central heating plant uses a fire-tube boiler fed by a spray-type deaerator; this P&ID shows feedwater, steam, condensate return, and makeup water with level, pressure, and flow controls.
What is in this drawing
Read the decisions behind it.
01
Used vessel_h for the deaerator and boiler type for the fire-tube boiler
02
Fail-closed diaphragm control valves for makeup, steam pressure, and feedwater loops
03
Explicit electric and pneumatic signal lines reflect ISA loop ownership
Use when designing or documenting a boiler feedwater and deaerator subsystem in institutional or district heating plants.
