Study Notes
- Taking readings helps operators diagnose problems.
- The shutdown procedure on a steam boiler gives one a chance to test safety interlocks without production interruption.
- Proper storage of an out-of-service steam boiler is critical for maintaining its longevity.
- The maximum operating temperature should not exceed 120°C in hot water boiler operation.
- When placing a steam heating boiler on line with other heating boilers already in service, have the boiler supply stop valve and return stop valve open.
- During a wet layup, sodium sulfite must be added to the water to ensure a sufficient residual remains for the layup period.
- The wet layup method is most often used for shutdown for standby boilers.
- Boilers are designed to withstand internal pressure and not external pressure.
- Water hammer can be caused by a sudden acceleration of fluid.
- Upon starting a fan, a typical parameter to observe would be noise.
- Rust in the gauge glass is an indication that corrosion is occurring in the system.
- Plants that have no backup power remain dead until utility power is restored.
- A boiler warm-up should be done slowly to minimize any differential expansion.
- A rapidly falling water level in the boiler may be caused by a faulty feedwater level controller.
- Pre-start checks of a fuel oil system should include a walk down of the oil storage and delivery system.
- While the boiler is warming up, it is good practice to check the low water cut off device for proper operation.
- Several days before shutting down a boiler, increase the rate of continuous blowdown, and increase the frequency of bottom blowdown.
- During the cold start-up of a boiler, slight smoking may occur in oil-fired furnaces.
- Stuffing boxes are designed to allow a continuous flow between the shaft and the packing of a centrifugal pump.
