Just in case anyone is hanging on the edge of their seats:


I spoke with numerous potters; no one was willing/able to help me.  So I gave it a go alone again.


The temperature stopped rising at 2175 (an additional two tanks and new regulator gave me 200 degrees!  Woo!) - I held there for quite a bit, then shut it down.  I reached anywhere from Cone 4 to Cone 6.  Still that same flame that just goes through one shelf and out the flue.  Still only one shelf with any reduction.  I used twice the amount of soda as I had in the past (2 kg in this 19 cu ft kiln), and there's really no evidence of having added more than before.  I believe the majority of it is going up the chimney (which, at that point, is less than 1" open at the damper).


In any event. This system, I believe, is fried. Done.  The amount of heat radiating from the two burners - and the gauges just behind them - is absurd.  I can't fathom the inter-workings to be still functioning properly.  (The heat in the burners is almost immediate upon lighting, as that blue flame is in the throat [but not to the orifice].)


Currently in the Frustrated stage, scheming about building a wood kiln.

Hooked up the four tanks, kept old regulator:  Same reading on pressure gauge - about 5.2.  (Marc expected 7-8.)


Replaced old regulator with new:  Pressure gauge reads 6.4 with one burner running, drops to 5.8 with both running.  


Marc has explained that the gauges should not drop when turning on an additional burner - and that it does do this, it indicates a volume issue.  He is trying to avoid switching me to high pressure, saying I've already spent too much money, and switching to high pressure would be much more.  But currently he has no ideas for me, other than using one regulator per burner.  But he wants me to fire it this way before trying the two-regulator option.


I'm currently trying to track down two retired ceramics professors who apparently live within 1/2 hour of me.  Because I'm not attempting this again alone.


I have to say, building a little wood-fired kiln (that Manabigama is so cute!) is looking better and better every day.  (With the given that I'd actually help fire someone else's before building my own.)

Have been working with Marc.  I will be receiving next week a new regulator and necessary connectors to string together an additional two 100-lb tanks.  If the four tanks don't give me a reading of more than 5.5 on the pressure gauge, I'll switch out the regulator.  If that doesn't help, I may be switching to high pressure.

This is the regulator on my B-2 burner.  It's a Chen Fong CF103.  I've found little information about it, but one particular Web site lists it as "Inlet Pressure : Max. 250 PSI 

Outlet Pressure : 0-60 PSIG "




From what we have read thus far, it seems as though we should give it a go as a low-pressure system with a new regulator.

Ohmyword, I'm confused again.  I thought that if I bought a high-pressure regulator, I'd have to switch the orifice.  But if I went low-pressure, I wouldn't.
