Coil Pulverizers for Boilers

The history of pulverization date back as early as 1824 and was envisaged by Carnot in a coal fired engine. In 1890 Diesel made use of pulverized coal in his diesel engine. The pulverized coal firing was first developed in cement industry which then migrated to power and process industries. Pulverizing coal in boiler is an important factor the overall cycle efficiency.

Relationship between Particle Size Distribution of Low ...

The impact of particle size distribution (PSD) of pulverized, low rank high volatile content Alaska coal on combustion related power plant performance was studied in a series of field scale tests. Performance was gauged through efficiency (ratio of megawatt generated to energy consumed as coal), emissions (SO2, NOx, CO), and carbon content of ash (fly ash and bottom ash).
