*Russ’s popper experimentation has shown some useful engineering details regarding systems that use arching in a hydrogen atmosphere.*
* * *The popper will become contaminated with tungsten powder after a relatively small number of arc discharges are done by Thoriated Tungsten Electrodes at high pulsed voltage.* * * *One theory about the cause of this tungsten erosion is that very high temperatures produced on the surface of the tungsten electrode vaporize the metal.* * * * http://www.google.com/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=2&cad=rja&sqi=2&ved=0CDwQFjAB&url=http%3A%2F%2Fwww.tandfonline.com%2Fdoi%2Fabs%2F10.1080%2F09507119209548203&ei=NWZ4UP_wI4_h0wHv7ICYBA&usg=AFQjCNFpzc-m6JddiXhQuTpwzh7UcZ7tPA&sig2=XNBN7NejJpiSQjFHs65oIg * * * * * *But Russ’s experiments speak against this theory because no erosion of the tungsten electrodes occurs when the arc happens in a helium envelope.* * * *There must be some other mechanism going on where hydrogen blows off or chemically alters the tungsten during electrode arcing.* ** *This testing has value for other like systems.* * * *In energy systems like those being developed by DGT, this electrode contamination could be an issue in regards to the life of spark plugs running in hydrogen over a long period of time.* * * *First the spark plugs will have a greatly reduced service life, and second, the electrode metal will contaminate the catalytic processes inside the reactor as more and more erosion occurs. * ** ** *Cheers: Axil* * * * * * * On Fri, Sep 14, 2012 at 10:46 AM, ecat builder <ecatbuil...@gmail.com>wrote: > Hi Vortex, > > Some updates on Papp development..
