<HTML>Hi George,
Yes, I think the finned stuff I have has quite a bit more than 6 fins per inch, probably very draggy as to gas flow (good with higher gas pressure). I figure that with a vaporizing burner it is not a good idea to use less than about 95 sq inches of gas flowpath cross-section per 6 gph, with flue area about 1/4 that, and even that is pushing it. My latest design has about 150 sq inches for 8 gph (like pushing a 23" Stanley to about 5 gph). Hope to get spotless clean burning under all conditions; looking at deep fireboxes and big mixtubes. For me, soot = unacceptable/redesign. Blue flame only. I'll scrap any burner that produces soot (or howls) under any conditions when properly tuned. Hope my junkpile doesn't end up too tall!

<HTML>Peter,
Your 6GPH design parameters sound good to me, 6GPH and 95 sq.in. of gas pass area gives a gas mass flow of about 1000 and with a crossflow boiler should do well. The mass flow could be increased a few times in the cooler economiser section. 6 fins per inch is very safe as it allows about 1/8th inch distance between the fins, you could always go to 4 or 8, for those like ourselves its what we find cheap that is near the ideal is what we will use/afford. Than at least our "junkpiles" havent cost us a whole lot!!
By the way this thread is getting endangered of being slid to an "older messages" page so if you don't see it on the first page go to the second and we can continue.
Good luck, George</HTML>

<HTML>Hi George,
Thanks for the vote of confidence. The proof is in the running. One boiler idea I am looking at would be incredibly cheap, but needs small-scale fabrication/run tests before it is "ready for prime time" in the discussion forum. Currently just a wild idea.
This boiler string has really broken the forum record in length! Maybe "Boiler Discussion Thread Part Two" is in order, so that current discussions don't end up several pages back.

<HTML>The concept of the Bonecourt boiler, pulse combustion and fireside condensation has had me out researching a bit. I am looking at a factory bulletin for Fulton Pule Combustion Boilers dated 10/04/93 discussing the exhaust vent materials. It states "Fulton has selected Saf-t vent because it features an advanced bonded metal design with an inner liner wall of AL29-4C, which is the only metallic material tested to the corrosion resistance requirements of UL1738. This alloy is a super ferritic stainless steel material designed for extreame resistance to flue gas condensate, chloride ion pitting, crevice corrosion and chloride stress corrosion cracking." Fulton claims 96 % efficiency when run in the condensing mode where the exhaust gas temperatures might be below 125 degrees F.. It sounds like they have pulse combustion well figured out at 32Hz and a free air noise level of 70dba running on natural gas. Has anyone had any experience with AL29-4C ?

<HTML>Hi Peter,
96% efficiency sure would be nice, but 70 decibels is pretty loud. Then again, it might be possible to muffle everything pretty well. I've seen awfully high prices quoted for some of those high-performance alloys. Hope the stuff you mentioned is cheaper, or is only needed in small quantities.

2.Tube length 1310 mm, outside diameter 100 mm.
3.Thickness 2.4 – 2.5 mm.
4.Quantity 3000 tubes.
-The tender for supply three ECONOMISER for steam boilers
I am looking to cooperate with your company.if you are interesting in the above mentioned tenders, tell me I will send you the technical conditions.
Awaiting your early reply.

I am seeking small boilers delivering 150 Lbs/sq. inch of 10, 15, 20, 25 and 30 H.P. for stationary application and small boats to operate on L.P.G., using sea water as feed water for generating steam and as well as cooling.

I do hope you have completed your experiment and have succeeded in developing the new type of Boiler.
