Comparison of Particle Densities and Blaines of Fly Ashes Generated in a Pulverized Coal Combustion Test Facility and in Pulverized Coal-Fired Power Stations

Abstract

The particle densities and Blaines of fly ashes generated in a pulverized coal combustion test facility and pulverized coal-fired power stations are compared. Particle densities of fly ashes from the test facility and the power stations show similar tendency with particle size of fly ash. Blaines of fly ash from the test facility and the power stations can be specified in the same manner. Blaines of fly ashes decrease with decrease in particle size, and increase with decrease in circularity of particle for all fly ashes from the test facility and the power stations. These results show that the properties of fly ash from the test facility can be reflected to those of the power stations.
