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.

Pulverized Coal Explosions in the U.S. Utility Industry. During 1981 the Electric Power Research Institute (EPRI) began a research project to study pulverized coal fires and explosions in the U.S. utility industry via an industry wide survey and explosion experiments.
coal can be handled safely and can be an efficient fuel, there are explosion hazards which are accentuated as the particle size is reduced. Particle sizes of coal which can fuel a propagating explosion occur within thermal dryers, cyclones, baghouses, pulverized-fuel systems, grinding mills, and other process or conveyance equipment.
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.

Ignition events that remained within the coal pipe created only weak pressure rise, while ignition events within the simulated pulverizer volume created explosions exceeding 70 bars (7000 kPa). These experiments showed that explosion characteristics depend on dust concentration, ration of pulverizer volume to coal pipe area, as well as coal type.

between explosion experience before or after the installation of inerting systems. LABORATORY EXPERIMENTS In order to obtain an understanding of explosion origin and growth, full scale coal pipe and simulated pulverizer tests were conducted at the Central Electricity Generating Board's (CEGB) Explosion Test Facility in Foulness, England4.
Fire and Explosion Prevention in Coal Pulverizing Systems. Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed.
218 INDUSTRIAL DUST EXPLOSIONS Phenomena of a Coal Dust Explosion To understand fully the hazards of using pulverized coal as a fuel in a cement plant, one must become familiar with the factors that typically enter into the development of an explosion.
Float Coal Dust Explosion Hazards Objective To increase awareness of float coal dust explosion hazards in the mining industry. Background In underground coal mining, dust is produced at the face, at conveyors, at transfer points, and by the normal movement of workers and machines. The coarse coal dust particles settle rapidly. However, the
