Obstacle Impacts on Methane-Air Flame Propagation Properties in Straight Pipes

Accidental flame initiation to propagation in pipes carrying flammable gases is a significant safety concern that can potentially result loss of life and substantial damage property. The understanding characteristics caused by methane–air mixtures within various extractive associated process industries such as coal mining critical developing effective safe fire prevention mitigation countermeasures. aim this study investigate visualise the explosion properties mixture straight pipe with without obstacles. experimental setup included modular starting pipes, an array sensors (flame, temperature, pressure), gas injection system, analyser, data acquisition control system. resulting observations indicated presence obstacles eventuated increase speed deflagration overpressure well reduction elapsed time propagation. maximum orifice 70% blockage ratio at multiple spots was increased around 1.7 times when compared for 10% methane concentration. findings will augment body scientific knowledge assist industries, including stakeholders develop better strategies preventing or reducing incidence accidental fires.
