Study Notes
Equipment Descriptions
- TCJC Gavelines: Synthesis of condenser - water station - PA
- Water Station CP1: Vapor Supply Turbine, Steam extraction, Feedwater, Condensates
- Condenser: The condenser is a key component in the steam turbine cycle for the water station. It's used to condense steam, lowering its temperature and pressure.
System Components and Temperatures/Pressures
- GSS: A component in the system, likely a steam generator, its temperature is ~220°C, pressure 66 bar
- GV: Another component, likely a steam source, temperature ~227°C, Pressure 26bar
- BP: A component (likely an abbreviation for "basse pression" - low pressure), Temperature ~185°C 11.5bar.
- ACO: A component in the water station (likely an abbreviation of a French term for a specific process), ~180°C, Pressure 70bar
- HP: Likely high-pressure steam, ~206°C 17.6 bar.
- R1-R6: These are likely various heat exchangers (or "réchauffeurs" -heaters) within the system, with varying temperatures and pressures.
- CEX: This is likely a condenser or cooler for a particular fluid, temperature 38°C pressure 40 bar.
- TPA: Component in the water system, likely an intermediary step, with variable temperature and pressure.
- APP: A component in the water system with variable temperature and pressure,
- R1: Heat exchanger, 57°C and 38 bar
- R2: Heat exchanger, 94°C, 37 bar
- R3: Heat exchanger, 134°C 36 bar
- R4: Heat exchanger 180 °C 35 bar
- R5: Heat exchanger, 200°C, 68 bar
- R6: Heat exchanger, 220°C, 66 bar.
Additional Notes and Descriptions

- Pages 2-8: Additional diagrams provide detailed descriptions supporting descriptions like "Water Stations," "Steam Stations," and associated parameters, notably steam temperatures and pressures for various components (R1 - R6).
- Pages 9-11: Describe the various components and functions of the system components further, including condensers, regulators, and associated mechanisms.
- Pages 12-16: Detail about maintenance, operational measures and troubleshooting, as well as descriptions of protections and safety measures for the equipment to maintain reliability and stability.
- Pages 17-24: Detailed information about operation, maintenance, and functions, including specific considerations for operation with one or more pumps or turbines offline or in emergency situations.
- Pages 25-28: Explanations of parts of the system, including heat exchangers, water circulation, and related safety mechanisms and protections.
