Common failures in thermal fuel oil boilers

 Because thermal fuel oil boilers operate under extreme temperatures, pressures, and demanding conditions, they are exposed to wear and tear over time. Understanding the most common failures helps ensure timely maintenance and prevents costly downtime: 

• Cracked or bulging tubes from prolonged high-temperature exposure or poor temperature control 

• Overheating and oil bumping, where poor flow or control leads to dangerous spray of thermal oil  

• Degraded heat transfer oil, suffering from oxidation or carbon deposit build-up, reducing efficiency and safety  

• Leaks at joints or seals, creating hazards from hot oil escape  
• Flow issues or poor cooling, such as pump failure or blockages, leading to inefficiencies and overheat risks
