Experimental study of effect of inert gases on extinction of laminar diffusion flames
The limiting fuel concentration and the limiting oxygen concentration required to maintain the diffusion flame and the limit flame temperatures were measured using a counterflow diffusion flame established in the forward stagnation region of a porous cylinder. The fuels used were methane and hydrogen, and three kinds of inert gas (nitrogen, argon, and helium) were used as the diluent. The flame temperature at the limiting fuel concentration coincides with that at the limiting oxygen concentration, and therefore, the controlling factor with diffusion flames under limiting conditions is the limit flame temperature. The limit flame temperatures for methane and for hydrogen, diluted with nitrogen, are 1,200/degree/C and 740/degree/C, respectively. 19 refs.
