Abstract
Provided is a correlation deriving method including the steps of: generating coal ash by incinerating coal; generating sintered ash by heating the coal ash at a predetermined heating temperature within a range of a combustion temperature of a coal burning boiler; measuring hardness of the sintered ash; measuring an exhaust gas temperature exhibited when coal which is to have the hardness is burnt in the coal burning boiler; and deriving a correlation between the hardness and the exhaust gas temperature.
