【 摘 要 】

Biogas has been utilized in many applications from direct and internal combustion because methane is its main flammable component and it can be produced by waste in household and industrial levels. This work focused on the experimental study of the in-house flammable gas detecting system for two biogas utilizing applications; the biogas engine and filler. For the application safety operations, the in-house system was designed to detect the biogas leakages and to turn off the biogas applications. The in-house system was fabricated on Arduino board and tested its functions in seven different butane gas releasing positions and three different biogas releasing positions. The experimental study showed that the system could detect butane in different distances within different periods of time. The system could turn off the biogas applications when it detected the butane gas at even the longest distance of 30 centimeters in an average time of 4.52 seconds. The system could also detect biogas and could turn off the biogas engine and filler in 2.33 seconds according to the set limited valve. The detecting system revealed its potential to be a safety feature for biogas utilizing applications; especially the biogas engine and filler, with acceptable price and reliable works.
