Centrale thermique de Duvha

Why should we not be surprised?! The story of wet coal, water shortage, diesel shortage and anything they can think off to avoid the truth why we have to have load shedding. Not really intended for the public, BUT, amazing how pics like these can get out even after Eskom put a blanket of secrecy around the whole incident. Eskom like hiding stuff like this? So I found out what happened at Duhva power station and the busted turbine. They were doing a test of the turbine overspeed protection system, and in short, the protection did not kick in. Conventional wisdom tells me that there should be a better way to test a protection system than to try and destroy the turbine and see if it feels like protecting itself, but that’s basically what they did. The turbine has a governor valve which controls the amount of steam coming into the turbine In order to keep it running at the right speed 3000 rpm for our grid frequency and then it has a main isolation valve to shut the steam off completely. The protections systems of which there are 3 independent systems, and a dude with his finger on the emergency button are supposed to close this main isolation valve in a fraction of a second when the turbine overspeeds. So they get ready for the test, they dump a helluva lot of steam onto the turbine, speed starts going crazy, it went from 3000 RPM to 4500 RMP in ten seconds they are generally only designed for 10 to 15% overspeed, all three protection systems should have kicked in by the time you get to 110%. Anyway, I don’t know why, but all three systems failed, and the dude with his finger on the manual trip button wasn’t at his post. So the result was a big bang, some fire and a lot of steam going where it shouldn’t go. Scary thing is Duvha has a shared turbine hall. All six units are placed in one long straight stripe, with no missile shield between them. And if you look at the third last pic you can see how big that shaft is, if that landed on another turbine it would have destroyed that too. They are very lucky they didn’t lose the entire station. So anyway, what gets reported in the news? “Unforeseen maintenance” at one of the units at Duvha requires it to remain shut down for 18 months. understatement of the century in my book. But you shut off the containment ventilation system at Koeberg for one hour and a radiation alarm goes off, then it’s a front page news national crisis. I give up.

All safety regulations are being followed and everything is being done in order and safety precautions

these are the different smokes from the furnaces.

I just loved evrything safty is their priority

Ma father worked here,, v j Ndlangamandla so am dying to visit again

Safety is their priority on everyone entering the station
