Development of Fly Ash Wuality Control

抄録

In order to effectively utilize fly ash as reproduction resources, it is necessary to qualify physical and chemical properties of fly ash and to collect an evaluated quality of ash by selection and storage. So a fly ash qualify control system capable of measuring and analyzing the component and the particle size distribution of ash in onstream was developed and a demonstration plant is now installed on site. This quality control system consists of an automatic sampling system, a residual carbon content analyzer, an elementary composition analyzer, a quality evaluation equipment and the like, and is capable of operating automatically. This paper introduces its quality evaluation technique in this system and the result of its effectively demonstration test as well as the state of operating machines.
