Question 119Steam Plants - Assistant Engineer70% to pass
Before blowing tubes in a boiler equipped with steam soot blowers, you should _______________.
AI Explanation
The correct answer is C) increase the boiler water level.
Before blowing tubes in a boiler equipped with steam soot blowers, it is important to increase the boiler water level to prevent the water level from dropping too low during the soot blowing process. This helps ensure adequate water coverage for the boiler tubes and prevents damage to the boiler from overheating or low water conditions.
The other options are incorrect because decreasing the steam pressure (B) or reducing the forced draft fan speed (D) would not directly address the need to maintain proper water level in the boiler. Decreasing the water level (A) would be the opposite of the recommended action and could lead to unsafe boiler operation.
