38. How to handle a decrease in steam pressure?
1. Report to the unit’s management and dispatch team immediately to arrange adjustments； 2. Monitor the operation status of the unit and make appropriate adjustments; in case of an emergency, report to the supervisor to initiate shutdown procedures.
As the steam pressure drops, the steam flow rate increases, which can cause the turbine to be overloaded. In particular, the blades in the last stages are severely eroded by water; at such times, it is necessary to contact the control room to reduce the load on the compressor and to inform the boiler crew to increase the steam pressure. If the situation cannot be controlled, the dispatch center should be notified to initiate an emergency shutdown.
