Porous structures can be used to avoid flame transmissions as it is done in flame arresters or breathing devices of explosion protected equipment. A detailed examination of the different flame transmission behaviours of different porous structures is performed using several methods of laser diagnostics. The flow behaviour is analysed using a Schlieren technique and the flame transmission itself is examined using laser induced fluorescence of OH radicals.
