Why Boilers Fail?

1. Historical Context

   • Boiler accidents have a long history of causing mass casualties.

   • The deadliest incident occurred in 1865 when the riverboat Sultana exploded, killing about 1,800 people.

   • In the early 1900s, thousands died yearly from boiler accidents, leading to the introduction of ASME boiler construction codes that drastically reduced fatalities.

2. Modern Trends

   • By the late 20th century, fatalities dropped to fewer than ten annually.

   • However, 1999 saw a surge with 21 deaths, including one accident costing over $1 billion.

   • Recent statistics show operator error and poor maintenance have overtaken low water as the primary causes of incidents.

3. Reasons for Failures

   • Boilers rarely wear out; unlike other machinery, they have minimal moving parts and can last decades if maintained properly.

   • Most failures occur due to incidents, particularly from:

     • Lack of water treatment

     • Improper water treatment

     • Negligence in maintenance

     • Human/operator errors

     • 
       
       

4. Key Insight

   • The main reason boilers fail is not age or wear but human factors and maintenance-related issues, underscoring the need for proper training, regular inspections, and adherence to safety protocols.
