Is this the longest cutting torch I've ever seen or something else ?

That is an oxygen lance. If I remember correctly, you start the cut with a regular torch and then turn on the lance which is just a piece of pipe with oxygen coming out.

Definitly an oxygen lance. You can do pretty much the same thing with an oxy/acetelyne torch. Once the you get the cut going all you need is oxygen. But not that large of course.

It's a oxy. lance. The pipe is packed with a substance (I've forgotten just what it is) to keep the fire going at the end of the pipe. The pipe and all melts as you use it. The pipe comes in sections that can connect together. The ones I've used varied from about 3ft. to 20ft. long. This thing cuts through just about anything, once I even cut through some fire brick in the ash hopper of a boiler to blow a hole out the steel casing of the other side. revpol

I think they are packed with magnesium but not sure.

At the steel mill they had a few torches that were about 10' long running on Natural gas to cut the billits going to the cooling bed when the automated torches would screw up.

Natural Gas ? I wouldn't think that would get hot enough ...

Lance, burning bar, whatever you want to call it is a piece of ½ iron pipe with iron wires filling the pipe, somewhat loosely.
The iron is the fuel, just as molten iron is the fuel when you are cutting with a torch.
Generally, you don't want to be hanging onto one that is only 10 feet long.

Natural gas cutting is accomplished by compressing the NG. About 20 years back there was an outfit selling the units that compressed the gas, around here, on the basis the price of acetelene was going thru the roof, and you could ammortise the investment in the compressor and storage in 5 years. I know of 1 unit that is in place. Compressed NG burns about like propane.
