Has anyone ever had a batch of bad propane ? My forge was working great until I filled my tank again. It will barely get to a red heat. Maybe something happened when I ran the tank till empty. Any ideas ?

Dennis,
You may have got your fill from the bottom of the sellers tank.
I think it is butane that collects in the bottom of propane tanks, but may be something else. I know when I lived in the true north the tank filling retailers always turned the tanks upside down with the tap open to empty them.

I've heard of this happening in the past, but have not experienced myself. Ghostdog is right about the butane, but moisture may also be a problem. I would question your supplier and see if they have any ideas. If they are like mine, I suspect they would do what it takes to keep you as a customer.

Thanks guys. With the price of propane lately, this could get upsetting. But I'd rather have bad propane than something wrong with my forge.

I have a venturi burner that has no filter. Several times over the years some bit of dust or debris got into the tint outlet nozzlehole. A quick cleaning with a tiny wirebrush wire and a jet of HP air got rid of the problem. I think commercial nozzles have a filter to stopdust. Just a thought.
