HWooldridge Posted June 9, 2009 Share Posted June 9, 2009 I never knew clinker would burn - thought it was primarily the byproducts of combustion. Quote Link to comment Share on other sites More sharing options...
easilyconfused Posted June 9, 2009 Share Posted June 9, 2009 That was my impression too. Going to be one big clinker. Quote Link to comment Share on other sites More sharing options...
Glenn Posted June 9, 2009 Share Posted June 9, 2009 Clinker is what is left after the solid fuel burns, usually composed of rock, sand, etc. Quote Link to comment Share on other sites More sharing options...
matt87 Posted June 9, 2009 Share Posted June 9, 2009 I've heard of adding slag back into bloomery furnaces to act as a flux but I can't see any benefit to adding it back to a forge, unless you're allowing the slag to build up to such an extent that when you do finally drag it out it's stuck to a bunch of coke. Slag is basically dirty glass. Glass does not burn. Quote Link to comment Share on other sites More sharing options...
jeremy k Posted June 9, 2009 Share Posted June 9, 2009 (edited) Steve - All your doing is adding the garbage(clinker) that would not burn from your previous fire, to the next one[as Glenn say's it can be rock,sand,and or whatever is mixed in with the coal that doesn't burn]. This is not helping you at all, because it is taking up the space that the fresh coal or coke should be in to burn. It may seem like it's burning up as you say but it's really filling your ash dump quicker and probably choking off the air supply. You may not be using as much coal or coke because the fire is not burning as it should, and most likely you've noticed that it is not as hot as it should be. Again this is due to the "lack" of fuel to burn because of the garbage(clinker). The goal Steve is to keep the clinker down to a minimum. Sometimes during long periods of forging the firepot needs to be cleaned out periodically of the clinker - this is dependant on the quality of coal you are using. I hope this helps you understand a bit on what the clinker actually is. Have fun forging Steve. - JK Edited June 9, 2009 by jeremy k Quote Link to comment Share on other sites More sharing options...
Bob JS Posted June 9, 2009 Share Posted June 9, 2009 Is it possible that you are burning the bits of unburnt coke that have stuck to the clinker? I suppose this means you will eventually burn 100% of the fuel you put in, but I would think the increased mess, blockage and heat absorbtion out weighs this. it must take up extra fuel to heat all that clinker up.
