Talk:Diffusion flame

Is a bunsen burner an example of a diffusion flame?

Typically a bunsen burner, like those used in high school chemistry labs, is not considered a diffusion flame. In fact, a bunsen burner is usually considered a good example of a premixed flame, because the carburetor at the base of the bunsen burner allows air to mix with the gas in the nozzle before it is ignited. You could get a diffusion flame if you closed the carburetors all the way, then only gas would flow out of the burner, and yes, then you would get a big sooty diffusion flame. In fact on the wikipedia site for premixed flames has a picture of a bunsen burner.

It seems like you are saying that bunsen burners are always diffusion flames from the context of your article, although that might not have been your intention. The context is not clear.

I get your point, that there are many different types of diffusion flames in general use, and that the fuel sources for them may be solid, liquid or gas. Maybe this can be stated more clearly. You have the candle example for solid fuel, but you could also add a liquid fuel source. For example, an oil lamp or a hurricane lamp uses a liquid, which then vaporizes and diffuses into with the surrounding air to form a diffusion flame. Maybe that might be interesting to readers. There are so many examples of diffusion flames in our daily lives that it's a little sad in a nerdy way that this stub has received such little attention. Glad someone got it started. --Mikofski (talk) 07:02, 29 May 2011 (UTC)
