    The amount of coal ash is the total of fly ash and clinker ash. The produced amount of Portland fly ash cement in specified by JIS R 5213 was only 73,000 ton in FY 2019, and the ratio of Portland fly ash cement to total amount of produced cements was only percent. So, the coal ash is mainly used for a raw material of clinker in Japan. Figure 4 shows ratio of used amount .

    Some coals formed clinker pots; that is, they developed a solid mass of clinker in the middle of the fire pot. This formation usually took the form of a basin, or bowl; that is, the first clinker formed near the grate decreased the air supply to the coal above it and restricted its burning, while the ash of the coal that burned at its edges built up clinker around it. Table 16 lists the coals ...
