Size Distribution of Fine Particles from Coal Combustion …

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 ...

The report noted that despite the larger particle size, a higher burnout rate would exist, resulting in lower unburned carbon losses and an improvement in boiler efficiency. Flue gas heat losses are predicted to remain the same as operating coal as an increase in hydrogen is counteracted by a decrease in carbon and a slightly lower mass flow of combustion air.
