Ok ...BARE with me... for aout 2 years i have worked with a gas forge with a single burner and it did the job...of heating up the iron but not forge welding heat...
OLD GAS FORGE... http://www.iforgeiron.com/gallery/showphoto.php/photo/964/ppuser/613
1 week ago i started changing the forge 1st thing 2 do was ...buy chamota mortar and glue the bricks 2gheter ...then i have made front and back dor to slide up and down... after that i have found an old burner that i did not used ...caz i don't know why i just built it and left it arround for days like this...and i have instald it in the forge..this is how it looks like after instaling it and how it burns http://www.iforgeiron.com/gallery/showphoto.php/photo/3736/ppuser/613 http://www.iforgeiron.com/gallery/showphoto.php/photo/3739/ppuser/613 http://www.iforgeiron.com/gallery/showphoto.php/photo/3735/ppuser/613 http://www.iforgeiron.com/gallery/showphoto.php/photo/3736/ppuser/613
....for some reason i just was not satisfied with only one burner ...the heat was not enof for forge weling afer 45 minutes of runing .I have to say that the flame was nice blue and no flames coming out from the inside of the forge ,,,i have scarped the old roof of the forge and made one to acomodate one more burner ...the old one as well... http://www.iforgeiron.com/gallery/showphoto.php/photo/3740/ppuser/613 reglued the bricks and mouted both burners in ...each burner has it's own GAS VALVE so i can use only one at a time ... one other thing that i did was to retract the burners inside the bricks.... the old setup had the burner inside the forge for about ...2 inches now hey are both in the middle of the bricks...When i lited the forge up ... surpize ... flames coming out from the forge blue ...red ...yelow all the colors u name it ...very frustrating and in my opinion dangerous caz the flame where quite big ....i only kept the fron door opend to the maximum and the gas pressure i have tried from 0psi up to 1.3 the same thing flames coming out.Then i tried to fire up only one burner ....like i did so many times befor ... using only one buburner ...but suprize .... flames outside the forge as well....
my question is WHY ? and how to fix this Do i need 2 open up the the back door as wel... ? what to do ?
10q for reading all my story and plz excuze me if i made speling mistakes
