What action should be taken if the temperature readings from a pyrometer are unusually high?

When the temperature readings from a pyrometer are unusually high, inspecting for overheating is the most appropriate action. High temperature readings can indicate that the boiler may be operating at unsafe levels, potentially leading to equipment damage or failure. Overheating can occur due to several reasons such as improper water levels, excessive fuel flow, or mechanical failure, among others.

Conducting an inspection allows an operator to identify the root cause of the high temperature, which may involve checking the equipment for blockages, assessing the water levels and quality, and verifying that the safety controls are functioning correctly. This proactive measure is critical for ensuring the safe operation of the boiler and preventing hazardous situations.

In contrast, increasing fuel flow could exacerbate the overheating situation by further elevating temperature levels, while reducing boiler pressure may not directly address the underlying cause of the high temperature readings. Adjusting water levels might also be essential, but without first inspecting for potential overheating issues, it is difficult to determine the right corrective action to take. Thus, prioritizing an inspection allows for a comprehensive approach to maintaining safe boiler operation.
