Maintaining stable operation during load changes in a supercritical plant involves: 1. Coordinated Control Systems: The plant’s DCS is programmed to automatically adjust fuel input, air supply, and steam flow to match the new load conditions. 2. Turbine Control: Adjusting the turbine’s steam inlet valves to control the amount of steam entering the turbine, ensuring a smooth change in output. 3. Boiler Control: Adjusting the feedwater flow and combustion process to maintain steady boiler pressure and temperature. 4. Gradual Adjustments: Making small, incremental changes to avoid sudden fluctuations that could destabilize the plant.
