Abstract

This paperwork is based on the data emerged from a conducted research related to a moisture influence on ignition sensitivity of air-methane gas mixture. For the purpose of this demarche it were used method of signal processing approach as it is data filtering and mathematical transform of the experimental data. In the first part of the paper, it was presented the spark test apparatus used for the experimentation and the results of the experimental data obtained during the tests with mixture air-methane and moisture. In the second part, it was proposed and presented the procedure used and theoretical model for the mathematical transform of the number of revolutions to which the ignition of the explosive test mixture has occurred. Also, in this part it is presented processed data by moving average filter using different window width values. In the third part, it is exposed and analyzed the results of the processed data. On this occasion it was found that moisture affects the ignition sensitivity of explosive air-methane mixture measured by ignition probability.
