What are two signs of boiler operating issues that operators should monitor?

Monitoring unusual noises and fluctuations in pressure are critical signs of potential boiler operating issues. Unusual noises can indicate mechanical problems, such as loose components or issues within the combustion chamber, which may lead to further malfunctions or dangerous situations. Fluctuations in pressure can suggest that the boiler is not maintaining a safe operating level, potentially due to issues like water supply problems, valve malfunctions, or pressure relief failures.

In contrast, consistent steam production and low fuel usage do not necessarily signal problems; they could indicate effective operation. Similarly, regular temperature readings and stable pressure would suggest that the boiler is functioning correctly rather than indicating any issues. High efficiency and low emissions are desirable operational characteristics but do not provide early warning signs of malfunctions or operational problems. Therefore, monitoring for unusual noises and pressure fluctuations is essential for maintaining safety and preventing boiler failures.
