  • Method and apparatus for calculating carbon content of fly ash
    Patent number: 6490909
    Abstract: A method and apparatus for calculating the volume fraction of carbon in the fly ash using a carbon in fly ash sensor that has a resonant cavity. The method first determines the volume fraction of ash in the fly ash. The method then determines the real and imaginary components of the dielectric constant of a mixture of pure carbon and pure fly ash, and the transmission factor of a signal from the oscillator in the sensor transmitted through the cavity due to absorption by material in the cavity. The method then determines the volume fraction of carbon in the fly ash by using the volume fraction of ash, the real and imaginary components of the pure mixture dielectric constant, the absorption transmission factor and the length of the cavity, the speed of light and the frequency of the oscillator.
