Explosion in Pulverized Coal Fired Boiler due to Waterwall Tube …

2010/3/17 · Waterwall tube failures are not uncommon in coal fired boilers. The failures reasons can be many starting from short term overheating to long term overheating, corrosion, erosion, etc. Waterwall tube failure in the burner panel corner in a tangential fired boiler and waterwall tube failure in the burner opening of a front wall fired boiler can lead to minor to sever explosion in the boiler.
