Study of Parameters and Theory of Sucrose Dust Explosion [PDF]

Energies, 2022
To investigate the parameters of sucrose dust explosion, the minimum ignition energy (MIE) and minimum ignition temperature (MIT) were evaluated. The experiments tested the MIE of sucrose dust under different conditions of dust quantity, ignition delay ...
