(seems I'm doing this a lot lately...)
This doesn't really have anything specifically to do with patches(though 
the media sampling features of MegaPOV can be helpful, and some of the 
new patterns would be useful), so it should probably be posted in 
povray.advanced-users, not povray.unofficial.patches. I set the 
Follup-To header to .advanced-users.

In answer to your question, some absorbing media should help a lot. 
Emitting media only adds to what is behind it, so you can only overpower 
things seen through it, but absorbing media blocks light, which will 
make your flame appear more "solid". Use the opposite color you used for 
emission, in other words "rgb < 1, 1, 1>-EmisionColor".
