Effect of sodium bicarbonate particle size on the extinction condition of non-premixed counterflow flames

Minimum Ignition Temperature of layer and cloud dust mixtures

“…As previously noted by some authors (e.g. Chelliah et al, 2003), the maximum increase in MIT C is obtained when extinguishing dusts are used, as they act as chemical inhibitors. This behaviour is due to the combined endothermic decomposition of the extinguishing dust, which subtracts heat from the system, and to chemical decomposition, which produces gases that deplete the oxygen concentration in the test chamber.…”

Catalytic inhibition of laminar flames by transition metal compounds

“…They found the most effective to be tetramethyl lead (TML, Pb(CH 3 ) 4 ), Fe(CO) 5 , TiCl 4 , SnCl 4 , SbCl 5 , and TEL (in that order), with TEL only slightly better than CF 3 Br, and TML about 11 times better than CF 3 Br. A limitation of this work, however, is that the agents were tested at only a single volume fraction.…”

“…Recent studies of inhibition mechanisms by K-and Na-containing compounds can be found in Refs. [1][2][3][4][5][6][7].…”

“…Metal-containing compounds have attracted attention for use in unoccupied spaces, or as benign additives to water, because of the extraordinary effectiveness shown in some laboratory experiments. For example, when added at low concentration [9], Fe(CO) 5 has been found to be up to 80 times more effective than CF 3 Br at reducing the burning velocity in premixed methane-air flames. Another example is methylcyclopentadienlmanganese tricarbonyl (MMT) [10], which was 40 times more effective.…”

Experimental studies on the extinction of methane/air cup-burner flames with gas–solid composite particles

“…Therefore, researchers turned to conduct the tests in well-controlled, simple, and inexpensive small scale flame configurations, such as counter flowing diffusion flame, premixed flames and coflowing diffusion flames, etc. [6][7][8][9].…”
