What is a common consequence of poor heat transfer efficiency in a boiler?

Poor heat transfer efficiency in a boiler typically results in wasted fuel and reduced performance. When heat transfer is inefficient, less of the thermal energy produced by burning fuel is converted into steam or hot water. This means that more fuel needs to be consumed to achieve the same output, leading to increased operational costs and ineffective use of resources.

Additionally, reduced performance in terms of steam generation can occur because the system cannot reach the required temperatures or pressures efficiently. This can lead to longer run times, higher emissions, and increased wear on components due to overheating or other stress factors. Overall, these consequences directly impact the boiler's operation and its economic viability.
