Question 274Steam Plants - 1st Asst/Chief70% to pass
When a soot fire occurs, damage to an economizer can be minimized if you _______________.
AI Explanation
The correct answer is B) maintain feed water flow through the economizer while extinguishing the fire.
When a soot fire occurs, maintaining feed water flow through the economizer is crucial to minimize damage. Continuing the feed water flow helps prevent the economizer from overheating and potentially failing due to the fire. Cutting off the feed water could allow steam pressure to build up, leading to further damage.
The other options are not recommended. Increasing the forced draft fan speed (A) could potentially fan the flames. Securing the economizer and opening the drain valve (C) could cause a dangerous steam pressure buildup. Injecting carbon dioxide (D) may not be effective in extinguishing a soot fire and could interfere with the feed water flow.
