That was probably more answer than you were looking for but I was thinking out loud(?) so I rambled on.

I am so happy right now! This was not to much information. In fact it has me re thinking several aspects of my forge and the burner I am thinking about building. Thank you so much!  I have so many more questions now but they are half formed. 

And yes I was talking about the forge with the nozzle cast directly into the liner. My step father was a stone mason and I was remembering that he favored a "Fiber Mesh" product added to the "mud" when he was making fireplaces/chimneys. It was a fiber glass like product that he said reduced cracking and helped reinforce the cement. My inital thought was that if you mixed something like that in with the refractory it might extend the life span of the liner but then I remembered that you could melt glass in the forge and that might do the exact opposite. I know that it is also kinda common to reinforce with steel (rebar and other such products) but you might end up with a similar problem. I was wondering if there was something we could add to the refractory to reinforce it? If not I guess we are all "doomed" to be rebuilding our liners/forges periodically?  The other side of that thought was that it looked that the thickness around the where the nozzle was a little thicker than the rest of the liner. It seems that the different areas would cool at different rates and maybe cause cracking. Have you noticed any of this or am I just too new to refractory and erroneously importing lessons that my stepfather taught me that only apply to cement?

Here was one of my nozzle experiments a while back.  We call it the flame blade.

This is wonderful! I was wondering you had any more information on this one? I was thinking about building something very similar but was wondering if you had any ratios or data for this kind of burner? I was initially thinking that the area of the opening (nozzle, nozzletts, blade?) should be 1 to 1.25 the area of the tube but this one looks like this one has a larger ratio? 

I was also wondering what happens if you 'force' air into one of your burners. I was was thinking  having a plenum around the top. I am guessing it would blow the flame out? or could it make your already impressive burners burn hotter? 

Sorry but one more if you will indulge my exuberance, but the one with the nozzle cast into the refractory, did you reinforce that at all? I would be worried that it would crack in the area around the nozzle?

Thank you!

I was introduced to gasifiers and built mine in this thread:

Hello BeaverDamForge. thank you for your comments. I am wanting to know more about this gasifier forge you built but alas when I click the link it redirects me back to the corn forge topic. which is frustrating because that is where I found the link. Could you help me with a different link? or the title of that discussion?

the spec sheet you can get when you order steel should  have information about how fast you need to cool the steel for proper hardening.

Darn I was hoping there was something like the steam tables From thermodynamics. I am pretty broke and most of my stuff is found metal. I occasionally know the series but not much else. I was hoping to narrow down some of it with some quench tests and cross referencing. 

Thank you so much for your help and for your knowledge! I really appreciate everything you bring to this environment!

Parks 50, 7-9 seconds 280°F

Parks AAA; 10-11 seconds 340°F

Forgive me Mr Sells if this was covered elsewhere and I have not found it yet or if this is something you would rather I read form your book, but how would I know what works best for the steel I am using and the project I am working on? If it is elsewhere could you help me find it? I am struggling to find what I am looking for using the search. I was wondering if there was a chart somewhere that equates the speed of quench to the hardness for different steels? Or is it really just use certain quenchants for certain steels?
