Question 192Motor Plants - 1st Asst/Chief70% to pass
Waste heat boilers may be equipped with vents on the feedwater heater heads to _______________.
AI Explanation
The correct answer is A) prevent air binding.
Waste heat boilers may be equipped with vents on the feedwater heater heads to prevent air binding. Air binding can occur when air accumulates in the feedwater heater, which can impede the flow of feedwater and reduce the efficiency of the boiler. The vents allow any trapped air to be released, ensuring proper feedwater circulation and preventing potential issues.
The other options are incorrect because: B) is for pressure relief, not air release; C) is for chemical treatment of the feedwater, not air release; and D) is for removing sediment, which is a different function than preventing air binding.
