Black Ink Posted January 29, 2008 Share Posted January 29, 2008 I think I remember not to long ago someone asking about a blackspot in thier NA forge and people were suggesting a blower well...One of my forges is a 10" I.D compresser tank with a 2" inlet vertical and I'm lucky enough to have an Industrial air mover for a blower.My problem is that I get a blackspot on the bottom of my forge,also I cant for the life of me get forgeing temps .I get just there but no cigar ,and if I add to much gas the flame goes carberised.I cant find a Cfm on the motor. Any suggestions TIA Jason:confused: Quote Link to comment Share on other sites More sharing options...
matt87 Posted January 29, 2008 Share Posted January 29, 2008 So... it's a gasser? Home-made I'm guessing. I'm also guessing it's forced-air. Mor einformation would be useful :D Quote Link to comment Share on other sites More sharing options...
HWooldridge Posted January 29, 2008 Share Posted January 29, 2008 It's a cold spot but how to fix it could come from several solutions. Choke the inlet, increase fuel consumption, lengthen the burner tubes, etc., are all possibilities. Quote Link to comment Share on other sites More sharing options...
Ice Czar Posted January 30, 2008 Share Posted January 30, 2008 + look at the angle on injection, combustion swirlpattern in the forge and around the stock, investigate deflecting the combustion for a more even heat distribution higher turbulance increase insulation heat retention Quote Link to comment Share on other sites More sharing options...
