What might indicate a problem with the fuel supply in a boiler?

An indication of a problem with the fuel supply in a boiler is often found in the signs of frequent shutdowns and erratic performance. These symptoms suggest that the boiler is not receiving a consistent or adequate flow of fuel needed for proper operation. When the supply of fuel is insufficient or interrupted, the combustion process can become unstable, leading to fluctuations in temperature and pressure, and may even cause the boiler to shut down to prevent danger or damage.

Consistent temperature output and normal pressure readings reflect stable boiler operation, which implies that fuel supply is stable. Similarly, efficient heat exchange would indicate that the fuel being supplied is being utilized effectively, thus showing no signs of fuel supply issues. Frequent shutdowns and erratic performance, on the other hand, point directly to issues with the fuel supply, meaning the boiler is struggling to operate as intended.
