| Abstract: | The 600MW supercritical once-through boiler units are introduced and the control strategies for the main steam temperature and reheat steam temperature are designed.Two-stage spray desuperheating control method,including the two-loop and cascade control strategies,is designed for the main steam temperature.The reheat steam temperature is controlled by regulating gas baffle and spray desuperheating auxiliarily.Operation experiences of the units indicate that the system operates well and the temperature contr... |
