Study Notes
Boiler Water Management System
- Electric heaters are used as a heat source for fuel oil (FO) and lubricating oil (LO) tanks.
- The drain from the saturated steam returns to the cascade tank.
- Fresh water from the auxiliary boiler is used to make up for shortages in the cascade tank drain.
- Boiler compounds are injected into the boiler drum for proper boiler water management.
- Fresh water is conveyed to the auxiliary boiler through the feedwater system.
- The inspection tank is used to inspect and maintain the quality of boiler water.
- Boiler compounds should be dissolved and injected into the cascade tank during low-load or standby periods.
- Boiler water samples should be taken from the boiler drum or downcomer for testing.
- Based on the results of the boiler water test, adjustments should be made to the chemical dosage and blowdown rate to manage impurities.
- The inspection tank is used to inspect and maintain the quality of boiler water.
- The drain from the saturated steam returns to the cascade tank.
- Boiler compounds should be dissolved and injected into the cascade tank during low-load or standby periods for proper boiler water management.
- Based on the results of the boiler water test, adjustments should be made to the chemical dosage and blowdown rate to manage impurities and maintain water quality.
- The recent trend in marine boilers emphasizes the importance of water quality management.
- Main boilers are typically used in large container ships, cruise ships, and other vessels that require high power output.
- It is imperative to prevent turbine plant accidents by maintaining good water quality.
- It is essential to ensure that the requisite quality standards for feed water, condensate, and boiler water are met.
- The main boiler feed water/condensate is used in the steam turbine.
- It is important to manage and maintain the quality of feed water, condensate, and boiler water to prevent turbine plant accidents.
