Studies on the Slagging Property of the Coals Used by the Utilities in Our Country
He Pei-au, Chang Zhong-xiao
As the coal slagging index presently in use does not completely fit the actual coal ranks of our country, an optimized mathematical model is therefore to be used to identify the slagging indexes. The model was developed based on the information obtained on about 250 different kinds of coal. A new method for coal grading is also established with the combination of gravimetrical sizing and high temperature microsocopy.
