✦ Synopsis

The quenching of flames propagating in a range of combustible vapours mixed with air has been investigated, using perforated metal sheeting and blocks with narrow apertures. The perforated metal was mounted inside an explosion tube along which the flame propagated. Measurement of flame velocities &owed that the velocities of vapourdir pames just able to propagate through the perforated metal were similar to those of propane-air fames. Experiments with ethylene games showed that. when the diameter of the apertures in the perforated metal was nearly as large as the quenching diameter, the flames were able to propagate through the apertures at considerably reduced velocities. This is discussed on a theoretical basis. The quenching of cool flames by perforated metal sheeting was also investigated.

The effects of a magnetic field on the cm&ion intensities of some excited species in hydrogen-oxygen flames have been studied. The emission intensities of HP0 and SnH were partially quenched by an esternal msgnetic field below 1.8 T. while those of CuH, CuCI, Sz, Se2 and Te, were not chansed by the
