PRE-HEAT
WITH BROWN'S GAS!
Pre-heating is
one of the all time best uses for Brown's Gas -
particularly on materials that require a lot of
energy to heat, like stainless steel.
One story I like
to tell is about a company that bought a Brown's
Gas machine from China (a 3,000 liter per hour
one) for $400,000. They weld large (several feet
in diameter) stainless steel tubes and pipes
together. Before these pipes can be welded they
must be pre-heated. This company was able to
underbid their competition and thus became one
of the largest welding companies in this
field.
This
gas allows you to pre-heat in a
tiny spot or
a whole area and it is clean, only water is the
by-product.
Since Brown's
Gas has a 'cold' flame, which applies the
potential energy directly to the material being
heated, the temperature that the material will
heat to is dependent on the size of your flame
and the material's ability to dissipate this
type of energy.
We've discovered
that different materials go to different
temperatures, the materials that are poor
conductors of heat, heat up very quickly when a
brown's Gas flame is applied. We have been able
to melt every material we've applied to this
flame. The higher the melting temperature of the
material, the faster this flame heats it
up.
The
kicker is that Brown's Gas will vaporize
materials like
tungsten and diamonds, but it will only very
slowly heat water. So you have to take care what
you want to pre-heat, because the gas heats
every material to a different temperature,
mostly depending on that material's ability to
shed heat.
