Question 60Steam Plants - QMED

The correct answer is B. The diagram shows the sequential order of heat exchangers that the main condensate pump pumps condensate through is B. This is the correct order based on the typical configuration of a marine steam plant, where the condensate flows from the main condenser through various heat exchangers to reheat and reuse the condensate before it is returned to the boiler. The other options are incorrect because A represents the main condenser, C represents the air ejector condenser, and D represents the gland steam condenser, which are not in the direct flow path of the main condensate pump.
