Question 170Steam Plants - QMED
70% to passWhich of the actions listed should be carried out immediately after securing the fires in one boiler of a two boiler ship?
AOpen the air registers wide to cool the furnace.
BSecure the main feed pump.
CDrain and refill the boiler with cold water.
DRelieve all fuel oil service pressure to that boiler.
AI Explanation
The correct answer is D) Relieve all fuel oil service pressure to that boiler. When a boiler is secured, it is critical to relieve the fuel oil service pressure to that boiler immediately. This is to prevent any potential fire hazard from the pressurized fuel oil. The other options are not the immediate priority - opening air registers or securing the feed pump can wait until the boiler is properly secured and cooled down. Draining and refilling the boiler with cold water could also be done, but relieving the fuel oil pressure is the most important and time-sensitive step to take right away when a boiler is taken offline on a two-boiler ship.
