Plant Operation Practice Test

Which action should be taken to ensure safe operation of the boiler?

1. Regularly check flame color

2. Remove ash and soot accumulation

3. Adjust the gas pressure weekly

4. Inspect the chimney once a year

The correct answer is: Remove ash and soot accumulation

Removing ash and soot accumulation is crucial for the safe operation of a boiler. Over time, the combustion process generates ash and soot, which can build up on various components of the boiler, including heat exchange surfaces and exhaust passages. If left unaddressed, this accumulation can impede heat transfer, leading to overheating and potential failure of the boiler. Additionally, it can create a fire hazard if the soot ignites. Regular maintenance of the boiler includes ensuring that these residues are cleared to maintain efficient operation and safety. By keeping the combustion area clean, the combustion process remains effective and emissions are minimized, contributing to both safety and efficiency. While checking flame color, adjusting gas pressure, and inspecting the chimney are all important actions in maintaining a boiler, they do not focus as directly on the prevention of risks associated with soot and ash accumulation, which can critically affect a boiler's performance and safety.
