Abstract
The importance of waste treatments is increasing because of the lack of resources and environmental problems resulted
from economic growth policy. Especially, the pollutant dust which is one of the wastes should be treated considerately
because it could cause secondary damages on the human health as well as environmental systems. Recently,
massive amount of coal fly‐ash is being produced in thermoelectric power plants. In this study, we compared two general
methods used in estimating the amount of unburned carbon in fly‐ashes to categorize the coal fly‐ashes into several
groups following their carbon contents. One is the ¡°loss on ignition(KS L 5405) method¡± which estimates the
change of mass after combustion, and it is generally used. Another one is measuring CO2 gas content by burning solid
carbon in the fly‐ash, and it is called ¡°CO2 analysis method.¡±
