Hill Posted July 8, 2009 Share Posted July 8, 2009 Am I wrong in guessing that this is the same principle as a water jacket used on a liquor still?....If so, how is the water circulated through the jacket to keep it cool? Just un across this and found it kinda curious. Maybe someone will know more about this. Here's the link: Modern Blacksmithing, 1904 Quote Link to comment Share on other sites More sharing options...
Hill Posted July 8, 2009 Author Share Posted July 8, 2009 ...and as a side note, this is one of the better books I have. Definately worth looking for. Quote Link to comment Share on other sites More sharing options...
brian.pierson Posted July 8, 2009 Share Posted July 8, 2009 Hill, It looks like a convection circuit for cooling. The heat from the fire will cause the water to heat up and rise in the tube. Cooler water will be drawn into the tuyer from the barrel as the hot water rises. It does not seem to be a closed system so the smith would have to watch the water level in the barrel so it doesn't run dry. Quote Link to comment Share on other sites More sharing options...
Charlotte Posted July 8, 2009 Share Posted July 8, 2009 (edited) One of the fellows I demonstrated with had an english side draft portable forge with a tuyre that worked exactly that way. Water for the coal and water for the tuyre was needed. Forge worked great by the way! PS I spoke with out looking at the picture. The one I say had a tank with a tube and baffle kind affair that hung on the side of the forge. Edited July 8, 2009 by Charlotte ps Quote Link to comment Share on other sites More sharing options...
Mike Ameling Posted July 8, 2009 Share Posted July 8, 2009 The whole idea was to help cool the metal around your tuyer. This helped slow down how fast it "burnt out". But those comments were also for people who had those forges running all day every day during the week. 12 to 16 hours per day for 6 days straight. So they tried to figure out other ways to help slow down the "burning out" of the metal at the bottom of their forge. In the same sections of that book you can also see examples where they took a CANNONBALL, drilled a couple holes through it, and used that in the bottom of their forge. The ... MASS ... of it helped extend the time they could run the forge before having to tear it apart and fix/replace that whole tuyer area.

Sam Thompson Posted July 9, 2009 Share Posted July 9, 2009 It's a thermal syphon, the heated water rises and cools as it sinks down the barrel. Mine is exactly like that with a welded up 3/8'' outer case and 11/4'' copper tubing. The tank is an old propane bottle which holds about 12gals and boils off about 1/2 gal per hour. I've used it heavily for about two years (often working 1''+sq) and there is no sign of burning. Quote Link to comment Share on other sites More sharing options...

bruce wilcock Posted July 9, 2009 Share Posted July 9, 2009 the advantage water tueirons had for heavy work was the amount of fuel burnt made big clinkers ,and the cold tueiron froze the clinker where it touched the tue and the air blast kept a hole open ,so we could work for longer and the clinkers came out in one peice with little time lost wating for clinkers to set .

piglet_74 Posted July 10, 2009 Share Posted July 10, 2009 Ya know, I almost read it cover to cover on the website you linked. I found myself as interested in the mans thoughts about the time period as I was his conviction for sand as a flux! Quote Link to comment Share on other sites More sharing options...
Jymm Hoffman Posted July 10, 2009 Share Posted July 10, 2009 When I was burning coal, I switched over to the side blast forge (not draft, I used a side draft chimney.) I eventually made a water cooled tuyre (the pipe leading into the fire, not that clinker breaker in a bottom blast forge.) I was burning up pipe until I made a water cooled tuyere. I simply made a tank for holding the water and made the tuyre out of 1" and 1 1/4" pipe, welding the end and making a jacket for the water to flow from the tank into the larger pipe. It was not as complicated as the link. In mine the larger pipe was welded to the tank and at the fire end of the 1" pipe. The 1" pipe went through the tank, welded on the back side where the blower was attached and also at the fire end with the other pipe to form the inside of the jacketed tuyre. I preferred this over the fire pot. I always knew where the clinker was and there was less wasted fuel as it could not fall through a grate or clinker breaker. The tuyre was long enough for the tank to sit behind the chimney and come out into the fire an inch or so. I just made certain it the fire end was slightly below level for the water to flow. But after switching to propane, I did not worry about these matters for daily use. Quote Link to comment Share on other sites More sharing options...
Sam Thompson Posted July 11, 2009 Share Posted July 11, 2009 I haven't got a camera but I'll try to get someone to take some photos soon. The more common type of water cooled tue is shown here:Vaughans (Hope Works) - Alcosa Coke and Gas Forges The air tube extends through to the back of the water tank.
