Flammability range of h2s
WebMar 1, 2006 · The flammability limits, rich and lean, of different H 2 –CO–CH 4 mixtures (with constant CO/CH 4 ratio of 1.0) at different initial temperatures are shown in Table 2 … WebThe upper and lower flammability limits of methane in air are located on this line, as shown. The stoichiometric combustion of methane is: CH 4 + 2O 2 → CO 2 + 2H 2 O. The stoichiometric concentration of methane in oxygen is therefore 1/ (1+2), which is 33 percent.

WebFlammability Limits The range of gas or vapor amounts in air that will burn or explode if a flame or other ignition source is present. Importance: The range represents an unsafe gas or vapor mixture with air that may ignite or explode. Generally, the wider the range the greater the fire potential.
