Nick O Posted March 28, 2016 Share Posted March 28, 2016 I recently bought a coal forge that had the blower body acting as the tuyere. I also bought a forge blower because the one that came with the pan was very old and cracked so now I have to make a new tuyere or chop up the blower case. The clinker breaker and air grate was missing so I had to by a clinker breaker off of Centaur Forge now all that's left to do is cut a hole in some 1/4in plate steel for the clinker breaker. What I need to now is should I make the hole oval or round? Also how much of a gap should I leave around the clinker breaker? I'm using coal about the size of your thumbnail. the clinker breaker is 2 1/2in long by 1 1/2in deep and 2in wide. Thanks for you time also happy late Easter!

Kozzy Posted March 28, 2016 Share Posted March 28, 2016 On my centaur firepot that takes the triangular breaker, the hole in the bottom of the pot measures slightly ovoid at 3-1/16" x 2-7/8". The long dimension is in-line with the axis of rotation of the breaker. The breaker measures 2-1/2 in that dimension implying about 1/4" of gap all around the breaker as new from the factory.

SReynolds Posted March 28, 2016 Share Posted March 28, 2016 I took a number of pictures of a forge I found this weekend. It has three slots in firepot (tuyere) 3/8" wide by 2.75" long. What blows me away is the clinker breaker. It has a cast iron wedge that is located about 1-1/4" below the air slots. Think about that and form a mental picture. Some company designed and manufactures these. What's the point? Is the clinker 1-1/4" BELOW the firepot? I see another popular breaker is a slotted nozzle that rotates side to side. Ok. So . . . . .tell me what cleans out the slag/clinker from THE SLOTTED HOLES where the the air passes? This is my own design. A 2 and sone inch solid steel cylinder that rotates inside of a hole. It destroys slag and clinker cuz the air passes s between the sides of cylinder and o.d. of the hole. The knobs welded to the cylinder chew up anything you place near it. Maks sense to me. I use a champion firepot with clinker breaker at a historic village and guess what. I have to use a 1/4"steel rod forced down into the air slots to break up the clinker etc to revive the air flow. . . Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted March 29, 2016 Share Posted March 29, 2016 on my slotted tuyere the clinker breaker is a cast curved T so that when you rotate it the edge of the cross bar fits up through the slot Quote Link to comment Share on other sites More sharing options...
