    AbstractIntroductionDescription of Tests and SamplingResults and DiscussionConclusionsAcknowledgmentsThe 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). The study revealed that the tested coal could be burned at a grind as coarse as 50% passing 76 microns, with no deleterious impact on power

    Measurements of the particle size distribution at the outlets of six coal-fired utility boilers showed a peak at a particle diameter near 0.1 micrometer. This submicrometer mode appears to be a general feature of coal combustion that results from a volatilization-condensation process in the boiler. At the boilers tested, the submicrometer mode contained 0.2 to 2.2 percent of the total fly ash

    Coal normally is availe to power plants in large lumps ranging from 2 mm to 50 mm size. Coal is commercially availe in different sizes known as “Run of Mine,” “stoker,” “slack,” etc. depending on their size. In the olden days, coal burning was done on grates without any change in size or pulverizing. Because of the large size
