Question 271Steam Plants - 1st Asst/Chief

The correct answer is C) Secure the fires and try to maintain the water level. If the boiler water level is falling due to a tube failure, the proper action is to secure the fires and try to maintain the water level. This is because a tube failure can cause rapid loss of water and potentially lead to a catastrophic event, such as a boiler explosion. Securing the fires will stop further steam generation and allow the operator to focus on maintaining the water level until the issue can be addressed. The other options, such as increasing feed pump speed or using two feed pumps, could potentially worsen the situation by further destabilizing the boiler's water level.
