Abstract:
A new microwave technique for measuring the gasification rate in a non-stationary mode is described. A feature of the technique is that to determine the mass loss during gasification, the time-varying resonant frequency of the microwave resonator with the sample under study is measured by sequential registration of the resonant characteristics of the sensor. This provides independence of the measurement results from the change in the quality factor of the resonator during fuel sample gasification. A sensor prototype which is a coaxial resonator in which the sample under study is placed in the region of maximum electric field was tested. Experiments have shown that the sensitivity (the ratio of the change in resonant frequency to the change in the inner diameter of the sample) of the new sensor design is two to four times higher than that of the previous sensor model.
