摘要
The inlet vanes for an induced draft (ID) fan in a power plant boiler are position controlled in accordance with the furnace pressure to limit the potential destructive power developed by the fan. The ID inlet suction temperature is sensed and a control signal is developed as a function of the inlet temperature to limit the opening of the inlet vanes during boiler startup.
