Scope
Scope: This document specifies the method for determining the carbon content in fly ash by thermogravimetry. This document is applicable to the analysis of fly ash samples with a carbon content of 3% to 15% by mass; Main technical content: The sample is placed in a thermogravimetric analyzer. First, it is heated in an inert atmosphere to fully release water and gaseous products of decomposable inorganic salts from the sample. After cooling, the atmosphere is switched to an oxidizing one and the temperature is raised again to allow the carbon to burn completely. The maximum weight loss in the oxidizing atmosphere is used to determine the carbon content in the fly ash.
