Awarpage of the soot blower element
Ban improper blowing arc cam setting
Cinsufficient steam pressure to the soot blower element
Da seized blower head bearing
AI Explanation
The correct answer is A) warpage of the soot blower element. If the soot blower element does not revolve freely, the most likely cause is warpage of the soot blower element. Warpage can occur due to the high temperatures and pressures the soot blower is subjected to, which can deform the metal and prevent the element from rotating freely. The other options are less likely causes - an improper blowing arc cam setting, insufficient steam pressure, or a seized bearing would not directly result in the element not revolving freely.
