The paper describes the principle features necessary for reliable and representative on-line unburned carbon-in-ash (UBC) measurement. The paper shows how modern on-line technology has been applied to obtain truly representative and reliable data for the evaluation of fly ash quality and boiler performance. To assure accurate UBC data from which to make operating decisions, one must achieve representative sampling in the ash stream, comparability of unburned carbon to loss-on-ignition (LOI) with various fuel types, a quality control regime to ensure the accuracy of the on-line measurement system in comparison with laboratory standards and auditing of the QC process.

In this study, utilization of coal fly ash with higher loss on ignition (LOI) for geopolymer mortar was investigated. The fly ash with approximately 9% of LOI was compared with Class F fly ash. Relationship between heat curing condition and strength was clarified. As the results, although compressive strength of geopolymer mortar with higher LOI was 30-50% smaller, it was available for geopolymer mortar as an alumina silicate material. The higher temperature and the longer period for initial curing, the higher strength was obtained. In order to decrease drying shrinkage, the higher temperature and the longer period for heat curing were required.
