Question 95Steam Plants - Assistant Engineer70% to pass
Which of the listed conditions aids in directing gland leak off steam from the low- pressure propulsion turbine to pass through the gland exhaust condenser?
AI Explanation
The correct answer is D) The use of a gland exhauster fan.
The gland exhauster fan is used to direct the leak-off steam from the low-pressure propulsion turbine through the gland exhaust condenser. The fan creates a negative pressure in the gland exhaust system, which helps to pull the leak-off steam through the condenser. This process allows the leak-off steam to be condensed and the condensate to be returned to the feedwater system.
The other options are incorrect because:
A) Steam pressure from the low-pressure turbine alone is not sufficient to direct the leak-off steam through the gland exhaust condenser.
B) Compressed air in the air pilot is not used to direct the leak-off steam.
C) Steam pressure from the high-pressure turbine is not involved in the gland leak-off steam management process.
