My dear Anons, i am having some trouble to find plans for a gas forge burner that dont use blowers. If youg uys help me out would be really awesome!!! Pic Related.
The only way to make a furnace that doesn't use blowers is to take advantage of convection or whatever it's called... heat rising out of your furnace causing fresh air to be pulled in.
I might be stupid and wrong, I'm kinda just pulling this out of my ass lol
The advantage to using blowers is you can seal heat inside your furnace, letting it reach higher temps and be more efficient.
