Gas burners for forges furnaces & kilns pdf download
By MikeyMay 7, in Gas Forges. I've just missed commenting on a discussion that has been closed a second time, and can't help but agree that it was probably the best course, but it brings up a recurring problem; and that is perhaps a need for the discussion on burner design as a general topic.
I haven't seen any other topic that gets heated any where near this fast in the Gas Forges section. I don't no why egos get so quickly bruised on this subject; there are lots of other details that can ruin a forge build; perhaps it's because poor work on the others isn't so spectacularly obvious; be that as it may, burners seem to be the item that folks show the most willful ignorance about in starting out, and the most deep denial over, when ending up!
I have heard a plethora of good advise on the subject from others and have given lots of it to boot. But, the strongest impression the comments I've heard formed are anger at the very idea that some have at doing a little reading on the subject before the fact, and a determination to argue after the fact, in stead of fixing the mess.
Perhaps the heart of the problem is too little attention paid about the WHY some detail insisted on is necessary? why can't a fella stick his gas jet near a hole in the back of a pipe, and just get on with the deal, huh; why not already?!?
Answer: You don't get the incoming air that gas stream is "sucking" in to swirl at the same time, so gas and air doesn't get adequately mixed together to properly burn; this is why linear burners are designed with a pipe reducer fitting or other funnel shaped part stuck on at its rear, and the gas jet gets mounted behind that. Answer: Then you have to makes some air openings in the side of the burner near its rear, and it becomes a jet-ejector style burner, instead of a linear burner, gas burners for forges furnaces & kilns pdf download.
Most people use holes for the air openings in their first burner, because it's the easiest form to make, and possibly on the "more is better" assumption, they drill way too many holes of as large as they can over way to large an area in the pipe, and then crown this effort by mounting their gas jet near the rear of the whole mess, instead of near its forward area.
Where did they go wrong so wrong? It foundered on the "more is better" assumption. Let the feathers fly. Mikey 1, posts. Frosty posts. Another FrankenBurner posts. ThomasPowers 77 posts.
Oh no, I'm going to defer to the "ex-spurts" lol. As all I know about gas burners is from cuss'n my proforge and reading you and Jerry's posts on the subject. I never thought to say this, Charles, but buying is maybe the better path gas burners for forges furnaces & kilns pdf download many smiths; if they dislike putting out the effort to understand what they are doing before they begin their build than why not?
Especially with some of the low cost choices available today. Devil Forge brand is a good example; are they a great product? Not hardly, but they will give more than someones money's worth, and bring beginners up to proper starting point where they can easily finish building a good forge, instead of a complete mess. The problem is getting any of the customers to check back in with us, once they complete the process. I will wade in on a gasser build some day and I expect you to be alive and cognient enugh to help me!
That goes for Jerry as well. I"m going to mostly lurk in this thread though, I'm far from finished sponging information on burners from Mike. This thread could not have come at a better time as I've just spent the last 4 weeks pouring over different burner information and trying to wrap my head around all the info.
I want to have as clear an idea as possible before I build my first forge. Thanks in advance for all the information. I'm now going to sit back and greedily absorbe all the upcoming knowledge!
And you are the vary sort of pupil I was hoping to give the advice to! No, this isn't a sales pitch; it has been pirated to the net for yes, so you can obtain a free copy.
Because there has been a lot of water flow under the dam since publication, I can update you and others who read this.
This is IMHO your best pass, but far from your only one. We can speak about burners from other designs; there are a number of worthy designs floating around; it makes no difference which one you want to go with.
My first burner was a Ron Riel linear design, which was quickly modified, and we where off to the races. With the MIG tip modification and a step style modified combustion "flare" burner nozzle it is still one of the best burner out there, as is the Frosty "T" burner, for a lot less work and money invested then either mine or Ron's.
Next we come to the Modified Side-arm burner, which has been around for many years; you can find a lot of knowledge about it on the Larry Zoeler Forge site, but he isn't available to give you personal input on the material, and my knowledge about it is a little weaker than is available than Jerry's and mine on the others burners. Sorry about all those typos; they'll be around for a while.
Also I don't mean to imply that you cant start with whatever questions are already on your mind. Please begin. Thanks in advance for all the help. To start with I'm probably going to be a pain with all the questions. It's how I learn best so better get them all down as best I can. First things first: I don't have any materials yet as I want to have a concrete blueprint with research done on it before I purchase anything.
Second: the only blacksmithing I have ever done was twist an iron firepoker in a historic forge as a class field trip almost 16 years ago. All that being said I've been interested in doing my own work ever since and only just recently found that I have the ability and time and space to do it at last. What I have my eyes on is a version of John Emmerlings ribbon burner. For a forge I would like to build a rectangle out of fire bricks.
Then line the inside and outside with refractory cement and round it out inside while it's workable. In theory anyway. Feel free to tear apart the design concept and please hit me with the worst of it. If I know all the issues before I start then I may design something better. For starters I would like to know what connections am I going to need from the propane tank to the burner. What recommendations would you share for choosing a material to transport the propane? And most important what safety features can I add between the propane and the burner?
The more the better. I don't care if it's overkill. I'll have more after but right now it's 2am here in Calgary and I have to be awake again in 4 hours. Do you have a copy of John's ribbon burner plans? Mike and I play mostly with Naturally Aspirated NA burners and a ribbon pretty much needs to be a gun blown burner. I'm sure a ribbon can be made to work with a NA air fuel supply but I haven't messed with one so I'd be speculating.
Your plan for a forge isn't very practical for a couple reasons. All that mud is a serious heat sink and backed by fire brick makes it worse.
It's going to need a LOT of fuel just to warm up let alone keep hot. If you used light insulating fire brick the brick will start breaking up quickly due to thermal cycling.
It doesn't like large temperature changes quickly, expansion and contraction needs to occur slowly, light brick i pretty darned fragile. It's never used as the fire contact surface in furnaces and kilns it's always used behind at least one layer of 3,f hard fire brick. You surely don't intend to put " of refractory cement over it. Plastering the outside gas burners for forges furnaces & kilns pdf download refractory is completely unnecessary and a waste of refractory.
It's like painting the inside of the sheet rock. Brick pile forges are a good first forge. They're not terribly efficient but they're easy to alter seeing as they're just stacked bricks. They let you experiment with shape and size before committing yourself to a permanent construction. Swirl isn't the only advantage that they can provide. If an impeller blade is attached at the large end of a funnel or pipe reducer at the burner's year end, a stronger vortex can be produced at the fitting's small end.
The impeller blade doesn't even need to move to get the effect, although a weak fan motor will work wonders. It is a given that a fluid running through a round restriction will form a vortex, but usually so weak a one as to make no practical difference, so that the term swirl or is more appropriate, gas burners for forges furnaces & kilns pdf download. But, for every minor increase in power added to a vortex its swirl and other benefit s are greatly magnified.
What other benefits? Increase flow of incoming air simultaneously with a large drop in air pressure in that flow; a magic combination that can be found in no other way. And with that we can move on to jet-ejector burners and their air openings. To begin with jet-ejectors induct more air into a naturally aspirated burner than can be found from a linear style with a rear funnel, unless it is equipped with a fan, and then it is no longer naturally aspirated, gas burners for forges furnaces & kilns pdf download, gas burners for forges furnaces & kilns pdf download if it is an impeller blade fan, gas burners for forges furnaces & kilns pdf download.
The way a jet-ejector's multiple air openings create swirl gas burners for forges furnaces & kilns pdf download from twisting into a small part of a turn, as air travels into the burner, just ahead of its mixing tube area; that my be found as part of a single tube shape Mikey burneror within a larger area built up in part from a reducer fitting and a larger diameter tube section Hybrid burner.
It can be made up as two gas burners for forges furnaces & kilns pdf download on a pipe fitting "T" buneror gas burners for forges furnaces & kilns pdf download from a single opening Modified Side-arm burner ; all are examples of jet-ejectors.
One fact of life we have to address is DRAG, gas burners for forges furnaces & kilns pdf download, which is the arch enemy of mixture flow. Any opening through which air flows creates drag as it passes by the air opening's edges, by creating eddy currents. Curved edges create more eddy currents then straight edges; the stronger the curve the greater the eddy currents.
Can you think of anything worse for creating drag than lots of little holes? Thus the advantage of just two larger holes in a "T" burner is far superior, and even the offside single hole of a Modified Side-arm burner trump them; this is despite the fact that both of the latter two burners have threaded openings that air must pass through, which threaded side holes don't!
Do we begin to appreciate how powerful eddy currents are at creating drag? Moving in the opposite direction, gas burners for forges furnaces & kilns pdf download, Rex Price, while still studying burner design with me, sent his version of what he thought he had learned of my ideas; his burner used slots for air openings, instead of my rows of holes, thus combining straight with curved edges; the improvement was remarkable.
So I came back with rectangular air openings to remove all curves from their edges, and beveled forward and rear edges for good measure. Such a boost in performance was gained that a radical new step stye flame nozzle became possible. First thanks for the advice in the forge Frosty. I will strip that idea and start from scratch again. I think I can get an old propane tank to cut down.
