Question 243Steam Plants - 1st Asst/Chief

The correct answer is D) loss of vacuum. Serious tube leaks in the air ejector condenser assembly will cause a loss of vacuum in the system. The air ejector condenser is responsible for maintaining the necessary vacuum in the main condenser by removing non-condensable gases. If the tubes in this assembly develop serious leaks, it will allow air to enter the system, which will disrupt the vacuum and lead to a loss of vacuum in the main condenser. The other answer choices are incorrect because they do not directly result from serious tube leaks in the air ejector condenser assembly. Fouled nozzles, clogged steam strainers, and faulty steam pressure are not the primary consequences of this specific issue.
