Question 181Steam Plants - QMED70% to pass
If the boiler water and condenser hotwell levels are normal, but the DC heater level is only 30% of full, you should _______________.
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.
