Generator Hydrogen Cooling System

Cornelia Felber

Hi all,

<i>"Another important consideration is to keep the hydrogen from leaking out of the generator, mixing with air and causing an explosion- or fire hazard where it might leak out of the generator."</i>

<p>thanks for the interesting information and help on this interesting topic.</p>

<p>Regarding this short notice of hydrogen leaking out of the generator, I was wondering, if anyone here has ever experienced hydrogen leaking through the sockets of thermocouples which are measuring the hydrogen temperature and leaking out, resulting in (luckily currently very very low) amounts of hydrogen in the control cabinet.</p>

<p>Does anyone have any experiences or good ideas, how to fix the insulation on those sockets without releasing the hydrogen?</p>

<p>Please excuse any bad description or wrong vocab ----> foreigner =)</p>

<p>Thanks all for your support,</p>

Is there any special fire protection system for hydrogen cooling generator casing? If yes than which type of?

Sir,

It's very helpful article for fresher like me. I'm first time involved in the basic design of Hydrogen cooling system, could you help me by providing basic guide line documents, design steps, calculations , or any presentation?

Thanks
 
Hi all,

I'm having a question on gas measurements of hydrogen cooled generator. We are currently measuring:

1. Air in CO2,
2. H2 in CO2, and
3. H2

in Air with gas analyser for our small 50 MW Fuji H2-cooled generator. There has been a 'rumour' around that it is also beneficial to measure oxygen level in the generator as well for explosion prevention purpose, in addition to H2 purity measurement. Is there a value in direct measurement of O2 in generator for explosion prevention? Does anyone have any experience with this?

Your replies are much appreciated.
