Combustion characteristics of three linear monohydric alcohols CH3(CH2)n-1OH (n = 16, 18, 22): Combined ignition experiments and molecular dynamics simulations

•The CH3(CH2)15OH, CH3(CH2)17OH, and CH3(CH2)21OH dust explosions were investigated.•The flame propagation height and velocity were explored.•The thermal decomposition of alcohols was investigated by TG test.•The combustion mechanisms of alcohols dust were depicted by ReaxFF MD.
