The recommended age limit for fire tube boilers is typically around 30 years. This is based on industry standards and practices which suggest that the materials and components within these boilers can start to degrade after this age due to factors such as corrosion, fatigue, and general wear from heat cycles.

After 30 years, the risk of failure increases significantly, and maintaining safety and efficiency becomes more challenging. Regular inspections and maintenance can extend the functional life of a boiler, but it is prudent to consider replacement or significant refurbishment when a boiler reaches this age limit to ensure adherence to safety regulations and operational efficiency.

While some boilers may still operate beyond this age under certain conditions, the 30-year mark is often recognized as a threshold where the functionality of fire tube boilers deserves careful evaluation and consideration for replacement.
