Question 27Steam Plants - QMED70% to pass
Which of the following labeled items of the illustrated air register and burner assembly represents the poke hole cover and would be temporarily removed to poke through a clinker? Illustration SG-0016
AI Explanation
The correct answer is B) 13, which represents the poke hole cover that would be temporarily removed to poke through a clinker.
The poke hole cover is a critical component of the air register and burner assembly, as it allows access to the combustion chamber to remove any clinkers that may form during the combustion process. Clinkers are fused ash deposits that can build up and restrict airflow, so being able to access and clear them is an important maintenance task for engineers operating steam-powered vessels.
The other options, A) 12, C) 14, and D) 15, represent different parts of the air register and burner assembly, such as the air register, the burner, and the ash pit door, but they do not specifically correspond to the poke hole cover that would be used to address clinker buildup.
