Pulverizer Fire and Explosions

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. Mill puffs most often originate in the under bowl area and can cause very destructive damage to the primary air ducting.

Pulverized Coal Explosions in the U.S. Utility Industry

PULVERIZED COAL EXPLOSIONS IN THE U.S. UTILITY INDUSTRY by RICHARD C. CARINI Manager, Engineering Administration and K.R. HULES Senior Staff Engineer INTRODUCTION 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 Pulverizer Explosions - Babcock Power

Pulverizer Age: Explosion frequency appears to be independent of pulverizer age. Explosion frequency has a slight decrease with pulverizer newness for bituminous coals. Conversely, explosion frequency increases with pulverizer newness for subbituminous coals. Coal Type: The subbituminous coals have explosion frequencies of about twice those of bituminous coals. The explosion values of lignite coals …

Coal Pulverizer Explosions - Babcock Power

The results of the survey materials indicate that the frequency of explosions is increasing. The average survey value of 0.31 explosions per year per unit shows a rise over previous averages. I Adjusted for the entire pulverizer coal fired utility industry, there is almost one explosive event each day.

Fire and Explosion Prevention in Coal Pulverizing Systems

operation does not result in an explosion. The rich coal/ air mixture has been shown to absorb the heat of the ignition source without igniting, and therefore it often produces no deflagration. The fire can be extinguished and the system brought off the line safely. Explosions consistently occur when the coal …

Coal Pulverizer Explosions - ASTM International

Laboratory experiments were performed in full-scale test rigs that allowed triggering and monitoring of coal system explosions on demand. 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 …

hard coal is transported to the furnaces on long conveyor belts (Fig-ures 2 and 3). The coal is largely so coarse-grained that there is no immediate risk of dust explosion. However, unavoidable abrasion across the whole transportation path, from conveying to the power plant and onwards to the combustion process, leads to fine coal dust

Coal pulverizer mill fires and explosions present a major safety and financial concern for owners and operators of coal fired boilers and utilities. Such incidents can damage or completely destroy the mill and ancillary equipment. Workers in the vicinity of the mill may be injured or killed by thermal injury, hot gases and/or flying debris. Another concern is combustible dusts on and around ancillary equipment in the area that can result in secondary explosions …
