Thread regarding General Electric Co. layoffs

Well, testing in Greenville does not necessarily show everything whats possible under the boundary conditions of customer sites. Combustion issues are quickly visible. Turbine issues after that. With further delay comes the compressor... Lets see whats coming up on top. All in all its not a good idea to mass roll out such a product so quickly.

Well, SOMETHING happened to the combustion system when they fired it up. The unibody liners came back to Greenville with holes big enough to throw a cat through. It may not be a textbook case of "combustion dynamics" but it was a serious failure.

Again, "combustion dynamics issues" would have been seen before the turbines were shipped during testing. There are no "combustion dynamics issues".

We are dumber than you could imagine. I guess we need a super-genius such as yourself to spell this out for us. Most of us understand cold air intake for a car, but the issue stated was that in the summer, Pakistan was hot. When air is hot, it is by definition not cold...

So, Super-Genius, what was the issue with hot air? Did the ambient temperature get up around 599 degrees Fahrenheit, and cut the air density in half, thus cutting the output by 50%?

The key to the Reuters article (assuming you actually read the news) is that the output was cut in half. How not-cold, Mr. Super-Genius, would the air have to be to cut the gas turbine output in half?

There is no way inlet clogging could drop a GT's output by that much. The intake would implode before dropping the inlet pressure enough.

If you get any serious salt ingestion the HGP (TBC) will be toast. Is the Punjab significantly salty (over irrigation?)

The most credible cause would be combustion dynamics issues.

There is a lot of bad information here. This is why you should not get your facts from an internet layoff forum. The real cause of the issue was your mom.

The salt in the air overloaded the filter house and was ingested by the GT causing the issue. Salt is different than sand. Please dont put sand on your popcorn when you watch Star Wars.

Air + fuel = output. If one is off then the engine combustion is off. How dumb are you people? You dont know how an engine works? Ever hear of a cold air intake for a car?

This article can't be true as none of these problems were seen when the HA's were run on the Greenville test stand.

Genuinely curious, can anyone elaborate on how the environmental conditions caused the inlet system to cut the output by 50%?

I’m sure the performance issues are the customers fault as well. Come on, be creative to blame the customer....

Have these units actually been formerly handed over?

If they are only producing half power I would assume they haven't done the acceptance performance test yet.

Not having diesel fuel supplied for the back up generator is very likely a customer issue.

Siemens would like to extend our appreciation of GE’s blame the customer culture. Keep up the good work.

Bad environmental data from customer? GE is actually trying to blame the customer because of environmental data? What data? It’s sandy in Pakistan? Hot in Pakistan. We already have “environmental data” from the entire planet. Again, blame the customer. Keep doing that GE and you will crash even faster!

The major failure was due to the air intake of the filter houses. This has nothing to do with the 30 mil engines. Fake news. Also btw the reason why the fikter houses were design wrong was due to bad envorimental data from the customer. Please leave the company you are the problem.
