The possible use of solar panels as flame detectors of triggered barriers
The presence of coal dust in methane-air mixtures increases the flame radiance. The higher the dust concentration, the finer the dust and the less incombustible content - the higher the radiance of the flame in the methane-air-mixture. If the thickness of the layer of methane-air is less than 3 m and the dust concentration is less than 10 g/m3, it can be assumed that the flame radiance is MT =0.65 MW/m2. If the layer is thicker, the radiance can be assessed by the value MT = 1.5 MW/m2, which is independent of the dust concentration, up to the lower flammability limit of the dust. The presence of coal dust has a favorable influence on the electrical efficiency of the solar detector. The efficiency for radiance from a small volume of methane-air mixture is about 0.033% and the energy generated by a single panel is 1 J. If the dust concentration approaches the lower flammability limit, these values are 0.7% and 3 J, respectively. The same values are achieved if the methane-air volume is thicker than 3 m.
