CUT IT WITH BROWN'S GAS!
The ERxxxx WaterTorch cuts thick iron fast, smooth and clean. Further, when we miss our cut from traveling too fast, we are able to pick up the cut right where we left off; (the oxidation layer is absolutely no problem for this torch). In fact, Brown's Gas will heat iron oxide faster than it will heat iron.
We have used our Water Torch technology on 'shapers' (automatic gas cutting machines) and it works like a dream, cutting 30% faster with a wonderful cut that requires a lot less work to finish (heat hardening is a fraction of using acetylene).
Remember, the flame itself is 'cool'. The flame directed against a material causes that material to go to it's melting temperature. Oxidized iron has a considerably higher melting temperature than non-oxidized iron.
We've also noted that iron that has been surface treated with a Brown's Gas flame is much more resistant to rust.
There are some additional side benefits. For some reason, thick scale or rust on iron will not spit and pop as you cut it, like it does with nearly any other torch. And when cutting bolts out of concrete it does it smooth and clean.
Working under an automobile is great because the flame energy is directed like a laser, not setting fire to grease, oil and rubber, just cutting what it's directed at quickly and cleanly. The flame is 'cool', so radiant heat is not setting grease, oil and rubber on fire either; great for muffler shops that chop off old exhaust systems with torches. In fact, thin metal like exhaust systems can be cut with the pure BG flame; no additional oxygen required.
Some Brown's Gas Advantages — Cutting of Iron:
Note: The reason bottled oxygen is added to any fuel-gas flame (and some plasma torches) to 'cut' iron is because the iron is not being 'cut'; it is 'oxidizing'. Once the iron is hot enough to oxidize, the extra oxygen assists this oxidation process.
Ordinarily, it doesn't matter which fuel-gas you use, the oxidation process (cutting speed) is limited by the oxygen assisting the oxidation, and so the cutting speed of most fuel-gasses is exactly the same.
Brown's Gas has a significantly faster cutting speed because the 'new oxygen' in the Brown's Gas actually speeds up the oxidation process. The 'new oxygen' is more 'reactive' than bottled oxygen.
BG Flame heats material much less than other fuel-gasses during cutting, thus has:
BG Flame will cut through rust with much less spitting and popping compared to other gasses
BG Flame will cut iron out of wet concrete without the concrete exploding
Brown's Gas has less density than most fuel-gasses, so more volume comes out the same size orifices. Brown's Gas weighs about 1/2 atmosphere, so is a 'Lighter Than Air' gas that does not concentrate to form explosive mixtures.
BG Flame has 'imploding' characteristics:
BG Flame is 'imploding'; the 'vacuum' drawing smoke from the work piece back into the flame and burning it. BG Flame implosion has a sustained inner vacuum that can be used for special effects.
Brown's Gas is easily adapted to current fuel-gas torch technology:'consumables' cost is almost nothing, torch tips stay clean. Significant time savings because torch tips do not require maintenance.
Torch tips stay cooler, helping them stay clean and reducing operator burns.
Use all the same equipment (hoses, valves, torch tips, etc.) as all other fuel-gas. With other fuel-gasses you need to change hoses when changing the gas.
Quick change between BG and fuel-gas technologies
Use of BG in current equipment requires minimal training.
Flame ignites easily and does not need adjustment to get the perfect mixture, saving time and not wasting gas.
In remote areas, there is a serious problem with accumulation of propane, oxygen and acetylene bottles because the cost to transport the bottles back to be refilled exceeds the cost of a new bottle. In this case, local water and electricity (may have to transport fuel for generator) can eliminate this waste and cost. Further, room is freed up in the transports for other cargo. Further, the danger of transporting the bottles is eliminated.
Carbon Monoxide from typical oxy-acetylene cut is 100 parts per million (recommended safety limit is 50 parts per million). It is a colorless, odorless gas that causes headaches, fatigue, nausea, dizzy spells, confusion and irritability; increased levels cause vomiting, loss of consiousness, brain damage and death.
Carbon mon-oxide builds up in the blood, having an cummulative effect on the body. In practical terms, studies show a significant rise in health related costs, time off, replacing employees due to carbon mon-oxide.
Brown's Gas has no carbon molecule so produces no soot, carbon dioxide or carbon monoxide and can be used in an enclosed environment with no harm to the user (unless something being burned produces noxious fumes). Even if smoke is being produced by the workpiece, the implosive BG flame tends to draw in and burn the smoke. Pure water vapor is the exhaust of the flame, maintaining a healthy operating environment.
