Biogáz robbanási határainak kiszámítása methán/széndioxid/levegö rendszer robbanási határ adataiból / Estimation of the explosion limits of biogas mixtures by using the explosiondiagram of a methane/carbon dioxide/air system

  • The knowledge of the explosion limits of biogases in air is necessary to define explosion protection measures. Biogases from agricultural plants vary however in their composition, so that for each gas composition the explosion limits would have to be measured. Frequently the explosion limits of biogas are therefore referred in the safety-relevant literature only to the methane fraction of the gas mixture, without indicating this additionally. This leads to the fact that the explosion ranges for the total mixture consists of methane, carbon dioxide and further residual gases are falsely specified. For this reason a simple method is presented in the following, which show, how the explosion limits of a biogas can be determined from its methane content using an explosion diagram of methane/carbon dioxide/air system. The explosion diagram was measured according to the German Standard DIN 51649-1. The presented calculation method supplies however correct results only if the nitrogen fractionThe knowledge of the explosion limits of biogases in air is necessary to define explosion protection measures.
