A5
B6
C7
D11
AI Explanation
The correct answer is C) 7. The item responsible for opening and closing the steam admission poppet valve at the appropriate times during element rotation is the cam (item 7) on the illustrated soot blower diagram SG-0023. The cam, through its rotation, actuates the poppet valve to allow steam flow at the proper times during the soot blower's operational cycle. The other options are incorrect because item 5 is the steam admission poppet valve itself, item 6 is the piston, and item 11 is the valve stem, none of which are directly responsible for the opening and closing of the poppet valve as the cam (item 7) is.
