anybody know the flame temperature of a gasoline "plumbers blowtorch"
type stove when it's burning blue? the kind in the center-left of this
picture, on the dolly...

I want to use it to pre-heat (heat soak) a pretty large piece of steel,
prior to brazing some stuff to it...

thanks for info guys :-)

The maximum flame temperture at the tip of the inner cone will be about
1900C if you have full aeration - pretty similar for all hydrocarbon fuels
burning in air. Doesn't mean you can get a big piece of steel up to that
temperature - that will depend upon all sorts of things like heat transfer
rate and heat loss.

It is not so much temperature, it is how many btu's you can put out on target.

Is that what they used to melt lead to seal soil pipe before PVC?

Those burners typically did not have a very high flame temp, even
getting a piece of steel red/orange hot took a long time. The flame is
quite diffused. But they put out a LOT of BTU's/ If you are trying to
preheat to the 600F range, these are great.

It would have been nice if you had also posted the start point.
It took a while to guess the starting point URL.

My opinion is that those bronze bearings were *not* cast in
place in the steel. If they had been, there would have been no need for
the key and the cotter pin. They would have had a firm grip on the cast
iron (just from its as-cast irregularities, if nothing else). They were
probably cast in sand.

No clues as to the temperature above. Stick a thermocouple in
the flame to see what you get.

Good Luck,
