Studies on the Unburned Carbon Content in Flyash from Pulverized-coal Combustion : 2nd Report, Comparison of the Experimental Results with Predicted Values

To discuss the validity of the prediction method described in our first report, five kinds of bituminous coals have been burned in two furnaces for a wide range of furnace temperatures and air-fuel equivalence ratios. Measured unburned carbon content in flyash is in good agreement with the predicted one in case of four coals and in the range of unburned carbon contents above 1%, verifying the validity of the prediction method.
