The flame propagation through a coal dust-air mixture in a spherical vessel was studied by means of a one-dimensional. Arrhenius-type kinetics and quasi-steady model. The model includes the evaporation of the volatile matter of dust particles into a known gaseous fuel (methane) and the single-stage reaction of the gas-phase combustion. Effect of venting devices as safety idea and the ... https://www.footballmediaservices.com/product-category/tig-starter-kit/
