johnptc Posted August 11, 2009 Share Posted August 11, 2009 i am looking for a design to be able to idle my blown burner. anybody have a successful design ?? Quote Link to comment Share on other sites More sharing options...
AndrewOC Posted August 17, 2009 Share Posted August 17, 2009 Sounds like a neat idea, i'm sure i've heard of some gas welding outfits having such a gadget. Looks like you'll be designing it and showing the rest of us! Back in the day when i worked out of furnaces we rarely had a need for it to idle; sure we would work on a forging for 10 or 15 minutes till it was cold, but there would always be another job still soaking inside. I wonder also if the furnace was on idle too long wouldn't it waste time and gas warming up again to use? When we did need to have a long thinking moment/ smoko/ tea break without shutting down the furnace we would cut the throttle down to save gas but keep it hot. Hope this pondering helps Andrew O'C Quote Link to comment Share on other sites More sharing options...
territorialmillworks Posted August 18, 2009 Share Posted August 18, 2009 Seems like any blown idle circuit would still require the blower to be running at speed...how about a pre-set stop for limiting the blower intake choke and a venturi style idle circuit like plumbed into the the mixer tube that would keep the burner going at a reduced rate. Like Andrew said, let us know....be safe Quote Link to comment Share on other sites More sharing options...
Muttt Posted September 5, 2009 Share Posted September 5, 2009 Just turn down the gas and the air but still keep it lit. Makes it a toaster instead of a jet engine. Doesn't matter if it spits and sputters a little ....... then when your ready, just turn it back up. I think and idle would be more hassle and expensive than it is worth. I don't like to turn my down anyway. My fire bricks glow when I am at temp. It takes a while to get them like that. Turning it down would waste gas trying to get it back to that glowing heat.

Danz409 Posted September 5, 2009 Share Posted September 5, 2009 if your looking for something for a solid fuel setup, i use a simple dimmer with a off setting for my forge and when a peace isnt in i turn it off compleatly. when i put the peace back in. crank it back up. saves a good amount of fuel.

HWooldridge Posted September 5, 2009 Share Posted September 5, 2009 Choke the inlet air on the burner with a damper and use a needle valve in the fuel circuit to reduce the fuel to the appropriate air level. I have one on my forge and will try to take a pic later today. Quote Link to comment Share on other sites More sharing options...
