Which of the conditions listed would indicate a dirty fuel oil strainer?
AI Explanation
The correct answer is D) Decreasing fuel oil pressure at the burner manifold.
A dirty fuel oil strainer will cause an increase in pressure drop across the strainer, which would be indicated by decreasing fuel oil pressure at the burner manifold. As the strainer becomes clogged, it restricts the flow of fuel oil, leading to a drop in pressure at the burner. This is the key indicator of a dirty fuel oil strainer.
The other options are incorrect because they do not directly relate to the condition of the fuel oil strainer. Decreasing fuel oil temperature, dirt and sediment in the atomizers, and decreasing pressure drop across the strainer are not reliable indicators of a dirty fuel oil strainer.
