A review on hybrid mixture explosions: Safety parameters, explosion regimes and criteria, flame characteristics

Research on the Mechanism and Propagation Characteristics of Combustion and Explosion of Natural Gas/Ammonia/Hydrogen Mixed Gas Fuel

“…They found that the explosion risk of mixed gas increased monotonically with an increased hydrogen mixing ratio and flow field intensity. Wu et al 37 provide a comprehensive overview of combustible gas safety parameters and insight into the explosive hazards of mixed mixtures. Sun et al 38 studied the combustion characteristics (such as flame structure, temperature, and matter field) and velocity field of ammonia/methane in industrial DLN gas turbine burners with the ammonia mass fraction up to 70% through numerical simulation and obtained the influence of increasing ammonia content on combustion performance and emission of mixed fuel.…”

Particles Morphology of Mechanically Generated Oil Mist Mixtures of SAE 40 Grade Lubricating Oil with Diesel Oil in the Context of Explosion Risk in the Crankcase of a Marine Engine

“…Oil drops floating in the crankcase atmosphere have diameters ~200 µm, and to produce a fine explosive mist [52], the droplets must have diameters between 5-6 µm [53,54]. The lower explosion limit for a mixture of oil and air is 47-50 mg/dm 3 (mg/L) [55,56].…”

“…In both cases, the droplet size distribution from evaporation and atomization maintains an approximately constant tendency compared to differences in droplet size that depend on the heater or atomizer distance, where the size distribution is recorded and analyzed [76,77]. Droplet size differences vary depending on the mist-forming substance [52,53].…”
