Document Type and Number:
WIPO Patent Application WO/2018/034514
Kind Code:
A1
Abstract:
The present invention relates to a method for measuring the amount of unburned carbon in coal ash, comprising the steps of: transmitting a signal having a predetermined frequency to coal ash; receiving a signal having passed through the coal ash; measuring the phase angle of the received signal; and calculating the amount of unburned carbon, which is contained in the coal ash, by using the measured phase angle, such that in the measurement and analysis of the amount of unburned carbon in coal ash, analysis can be performed quickly by using a frequency phase angle.
