Pulverizer Fire and Explosions

Pulverizer housing or burner lines are glowing red; Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill “puffs”. Explosions in a pulverized coal system are normally called “puffs.” A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature.

Explosion in Pulverized Coal Fired Boiler due to Waterwall

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.
