Question 268Steam Plants - 1st Asst/Chief
70% to passWhich of the casualties listed is apt to occur immediately after a high water casualty?
AExcessive steam pressure
BWater carryover to the turbines
CExcessive superheater temperature
DMassive tube failure
AI Explanation
The correct answer is B) Water carryover to the turbines. After a high water casualty, where the boiler water level rises above the normal operating range, the immediate concern is that the excessive water will be carried over into the steam turbines. This can cause damage to the turbine blades and other internal components due to the presence of liquid water in the steam flow. The other options, such as excessive steam pressure, excessive superheater temperature, or massive tube failure, are not the immediate consequences of a high water casualty, but may occur as secondary effects if the high water condition is not addressed promptly.
