Hello fclergue,
Copper reactor tube, never tried, it seems a bit tangent with the heat, especially on a petrol engine. Copper rod I mentioned that the temperature of the rod is not as high as that of the copper which supports it, but it is the least effective of the few metals tested. Brass I have not tried, duraluminium c, is as good as steel and if it is easily eroded rapid oxidation, when the duration I do not know, test only a few hours.
For the reactor outlet pipe, it is most often red copper pipe, commercially available, the materials tested, is steel tube with T in cast iron.
stainless steel tube, flexible neoprene (hydraulic conduit although in the long term this does not reside in a 100% pant warm).
It is not so much the material of the outlet duct that affects walking but rather the section, the length, as well as the elbows, all my ducts are made of copper, the shortest possible without direct bend, the duct is covered with a red silicone thermal insulating sheath. on this conduit I weld a type K thermocouple, it is my reference to control the reactor. After a certain amount of gas flow, in the case of the petrol engine, the copper pipe turns black inside and verdigris in the connections with the intake manifold (probably due to the nature of the different metals, aluminum and copper , or condesation at the expense?)
but it is details without great importance.
The inlet pipe into the reactor should not even exist, the reactor should fire directly into the bubbler, or put the bubbler very close and make a chamber, or a large duct which feeds the reactor,
the vapor should not undergo this compression or rolling in a too small tube before arriving in the reactor, therefore as much as possible avoid a long bubbling reactor pipe,
Andre
