Inspections also play a crucial role in detecting any signs of corrosion or leakage. Corrosion can weaken the boiler’s structure and lead to leaks, which can be hazardous. By identifying and addressing corrosion at an early stage, potential accidents can be prevented, and the boiler’s lifespan can be extended.

Furthermore, inspections help ensure that the boiler is operating within the required parameters. This includes checking the pressure, temperature, and fuel combustion. Any deviations from the recommended values can be corrected promptly, preventing any potential damage or accidents.

In conclusion, regular cleaning and inspection are vital for maintaining the efficiency and safety of fire tube boilers. Cleaning helps remove soot and scale, which can hinder the heat transfer process and reduce the boiler’s efficiency. Inspections, on the other hand, help identify any potential issues or defects that may affect the boiler’s performance or safety. By following these maintenance guidelines, fire tube boilers can operate optimally, ensuring reliable steam generation and minimizing the risk of accidents.
