Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A correlation deriving method, comprising 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. 2. A correlation deriving device, comprising a correlation deriving module configured to derive a correlation between: hardness of sintered ash obtained by heating coal ash at a predetermined heating temperature within a range of a combustion temperature of a coal burning boiler; and an exhaust gas temperature exhibited when coal which is to have the hardness is burnt in the coal burning boiler.
