Gas injection into forced air burners ?

Mark, did you look at the wolly worm type of extension J. made on his burner.
I am a little concerned about combustion within the pipe if the pressure drops too low but so far no one seems to have had the problem.
 
I guess any forced air burner could catch fire in a power/fan failure. I like pushing the envelope anyway. Might set this forge up outside just to be safe.
 
Hey guys, for proper safety a normally closed solenoid valve can be placed in-line with the gas feed. Here's a suitable one that only costs ~$50:

ASCO Solenoid Valve
Cat # 8262 G78
Fuel Gas - 40 PSI
1/4" NPT

Now as long as you're always close to your forge while it's running and can get to the shut-off valve quickly in case of a power outage there shouldn't be a problem....but if you place this solenoid valve in the system, then if power goes out (and hence your blower shuts down) the gas supply will be shut off too. Also, by having this on your forge, if you ever pick up a PID controller (can be had for good prices on ebay if you look long enough) you can use the solenoid valve to modulate the gas flow to your forge and make it temperature controlled! :)

Hey Darren, who carries that solenoid valve? I'm curious to look at one and I do have a controller I need to set up one of these days.
 
Hey Mark,
Can't find the original site where I got the design, but I'll upload a diagram when I can get it ready.

Hey Dave, if you go to http://ForgeGallery.EllisCustomKnifeworks.com you'll see the forge gallery I'm setting up to become a resource for forge building ideas. There are only two submission updated there right now, but by the weekend, there'll be something like 20 (and more if more people would send me their pictures and info!!!), anyway, I'd love to have pics and diagrams of your forge up there too if you wouldn't mind! :) In my updating of the new ones I'm putting up I put a little blurb at the end about the maker as well as a link to their website if they have one too.

If you want to make a do-it-yourself valve, get a 120/24 volt transformer from Radio shack and a selnoid valve from Homedepot. I'll leave the hookup to your imagination but as long as there is 120 power, the valve will stay open, when there is not the valve closes.

Hi Pete...r...err, forgot your name again... anyway, the only problem with that would be the solenoid isn't rated for propane use and the seals might break down prematurely....having said that, I know of a well known bladesmith who has a bunch of forges all set up on air quick disconnects. He just changes them out each year to avoid any problems with the seals...


wait, it's Don right!? I think I finally remembered your name!!! :)
