Microwave attenuation method has been one of the possible methods to measure the carbon content in fly ash online with high accuracy in recent years. However, the uncertainty of the shape of fly ash accumulation in waveguide brings many errors to the measurement of carbon content. To correct the errors, based on the study of ash level measurement, the influences of different inclined planes on the measurement of medium height and transmission attenuation are compared. Then, a model was established to quantify the influence of slope degree on carbon content of fly ash. Finally, the interference of different inclined planes on the measurement of carbon content in fly ash is analyzed. The result shows that with the increase of the inclination angle of the dielectric top slope in the waveguide, the transmission attenuation effect gradually increases. This will lead to the large measured value of carbon content in fly ash.
