Question 181Steam Plants - QMED

70% to pass

If the boiler water and condenser hotwell levels are normal, but the DC heater level is only 30% of full, you should _______________.

Aincrease the speed of the condensate pump
Bbypass the vent condenser and third-stage feed heater
Copen the makeup feed
Dopen the feed pump recirculating valve wide
AI Explanation

The correct answer is C) open the makeup feed. The makeup feed should be opened when the DC heater level is only 30% of full, while the boiler water and condenser hotwell levels are normal. This is because the low DC heater level indicates a lack of water supply to the heater, which should be addressed by opening the makeup feed to restore the proper water level. The other options are incorrect because: A) increasing the speed of the condensate pump would not address the low DC heater level; B) bypassing the vent condenser and third-stage feed heater is not the appropriate solution; and D) opening the feed pump recirculating valve wide would not resolve the issue with the DC heater level.
