Deteriorating Hydrogen Purity in Generator

12/31/2011 5:09 AM

We have 220 MWe generator , the rotor being cooled by Hydrogen. We are facing problem of continuous declining Hydrogen purity. We are finding Nitrogen and other gases in Hydrogen. Anyone faced similar problem before? What may be the reasons? The generator is sealed by seal oil ( ISO VG 32) by maintaining differential pressure between oil and Hydrogen.

"The bearings have to be leak-tight. A hermetic seal, usually a liquid seal, is employed; a turbine oil at pressure higher than the hydrogen inside is typically used. A metal, e.g. brass, ring is pressed by springs onto the generator shaft, the oil is forced under pressure between the ring and the shaft; part of the oil flows into the hydrogen side of the generator, another part to the air side. The oil entrains a small amount of air; as the oil is recirculated, some of the air is carried over into the generator. This causes a gradual air contamination buildup and requires maintaining hydrogen purity. Scavenging systems are used for this purpose; gas (mixture of entrained air and hydrogen, released from the oil) is collected in the holding tank for the sealing oil, and released into the atmosphere; the hydrogen losses have to be replenished, either from gas cylinders or from on-site hydrogen generators. Degradation of bearings leads to higher oil leaks, which increases the amount of air transferred into the generator; increased oil consumption can be detected by a flow meter associated to each bearing.[9]"

No, no, no. This is actually caused by low energy spontaneous nuclear fusion of fourteen Hydrogen molecules that transforms into a Nitrogen molecule. This process is accelerated by the high magnetic and electrical fields that happens inside the metal tubes that are trying to retain your coolant. Some of the Nitrogen does come from a fission double splitting of the Nickle used in the magnetic cores in your generator. Over time this splitting process will significantly deteriorate the efficiency of your generator. These atomic changes are necessary to explain where the rare gas Nitrogen could possibly be coming from.

Well I'm quite sure • Lyndoor™ Industries • has a preventative device that can be installed at great expense to remedy this situation post haste...We may be able to tap some of this free energy to suppliment the overunity characteristics so frequently occuring in SNF(spontaneous nuclear fusion) devices...∞

No, they don't have access to that technology, yet. Once they pay me my last consultation fee I'll consider their manufacturing capability.

You disclosed the technology to produce gold in my backyard that can be sold at half of current prices. keep track of gold on LME,

No, you sell the gold at the current price regardless of the cost of acquisition or fabrication.

I've got to careful here. It's starting to become too much fun proposing ludicrous Physics here. I know you're also joking with me, but I now see the lure of running a confidence scam. Money may send people down this path but the ego boost is dangerously addictive.

The next Nobel award Winner , perhaps your brain has also fusioned (fused).
