GB/T 31424-2015 specifies a method for determining the viscosity of coal ash using a high-temperature viscometer with the rotating cylinder method. The coal ash sample is melted at high temperatures (typically above the ash melting point), and its viscosity is measured at different temperatures, which provides important guidance for the design and operation of slag discharge systems in coal gasification and combustion furnaces.
