In steam turbines, temperature, pressure, and flow rate are controlled through various mechanisms. To manage temperature, steam is preheated before entering the turbine, and desuperheating techniques are employed if necessary. Governing systems adjust throttle valves and nozzles to regulate steam pressure, while bypass valves divert excess steam to maintain optimal levels. Flow rate is controlled by adjusting throttle valves and utilizing bypass systems to manage the amount of steam entering the turbine. Advanced control systems like Digital Control Systems (DCS) and integrated strategies provide precise, automated regulation.
These methods collectively ensure safe and efficient turbine operation, optimizing power generation in various industries.
