Abstract:To characterize the
inerting effect of N2/CO2 mixtures containing
various proportions on methane–air explosions,
a series of experiments were conducted in a 20 L spherical vessel
under the normal temperature (25 °C) and normal pressure (101
kPa). Six concentrations (10, 12, 14, 16, 18, and 20%) of N2/CO2 mixtures were selected to analyze the suppression
of methane explosion by N2/CO2 mixtures. The
results indicated that the maximum explosion pressure (p
max) of methane explosions was 0.501 MPa (17% N2 + 3% CO2… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
