What a generator under heavy load looks like

Kinda worried about the fire sprinklers near the ceiling. Oh well.

I was going to say the same thing about radiated heat. Check out the black spots on that ladder next to the exhaust pipes.

How long can that thing operate with the exhaust system glowing red hot, and still be safe?

Lol idk, till it self destructs, I guess.

It might be ok, or even good to heat it up and burn some build up out of it's internals. But I can't imagine anyone would allow it to go on that long.

Lol imagine the smell in that room.

[ - ] Not_a_redfugee [op] 5 points 1.7 yearsSep 25, 2023 16:00:32 ago (+5/-0)*

It smells hot. It's a natural gas unit, not diesel, so im moreso testing it's capability, not so much burning out wet stacking gunk like with a diesel.

I believe it's a MAN engine. Running on natural gas.

It's got the ol reliable altronic magneto ignition system looks like

[ - ] ProudRebel 1 point 1.7 yearsSep 25, 2023 17:35:12 ago (+1/-0)

That's exactly how it's designed to operate.

[ - ] HeyJames 1 point 1.7 yearsSep 25, 2023 19:33:25 ago (+1/-0)

Lol the exhaust system will glow hot at full load indefinitely and be just fine

Running as it should.
There are fail safes in place for preservation of equipment

You should also worry about heat detectors. Some are rate of rise, other are a set temperature. And is that ladder really up against a turned-on generator?

[ - ] Not_a_redfugee [op] 1 point 1.7 yearsSep 25, 2023 17:27:21 ago (+1/-0)

Nah the ladder was used by the maintenance people to disable a fire detector on the ceiling, so that it doesn't go off and call the fire department and set off fire alarms all throughout the building, like last time..... Lol.
Its not touching the gen or exhaust pipes

[ - ] 2Drunk 1 point 1.7 yearsSep 25, 2023 17:54:57 ago (+1/-0)

I wonder if it's hot. Should I put my hands on it?

[ - ] JudyStroyer 1 point 1.7 yearsSep 25, 2023 20:21:03 ago (+1/-0)

Only way to know for sure

If you can't read, i guess there's only one thing to do to see if it's actually hot....

[ - ] HonkyMcNiggerSpic 0 points 1.7 yearsSep 25, 2023 16:06:38 ago (+0/-0)

That kind of heat will eventually take its toll on a lot of things.

Yeah MTUs are top notch.

Air cooled exhaust on stationary equipment is junk. Constant exhaust leaks if it's ran for any significant period under heavy load

[ - ] Not_a_redfugee [op] 0 points 1.7 yearsSep 27, 2023 20:10:41 ago (+0/-0)

To be fair, most places' backup gens are usually overkill for what it needs to actually power in case of an outage. They will likely never be loaded as much as when we're load banking them.

Yeah I've worked on a lot of fucked up shit. Enough to know that i really hate dry msnifolds on stationary equipment. Worked on a 3606 that had 113,000 hours on it the other day. It's still shitting and getting like a champ though. 3600s are great engines honestly nothing is cheap but they're rock solid

Ooo toasty! What’s the load being driven?

[ - ] Not_a_redfugee [op] 1 point 1.7 yearsSep 27, 2023 20:09:02 ago (+1/-0)

A giant space heater. Coils of wire and a bunch of relays and shit and a badass fan to keep it from burning up. Aka a load bank.

While load testing a 1.2MW genset on a ship, they put the load test bank inside a partially enclosed area on the ship, presumably to keep it out of the weather. We took it up to 1.4MW to calibrate the main breaker, and the overhead lighting starting dripping plastic; it was raining hot plastic. I don't know why, but they always put the biggest idiots in charge of projects. Dumping that much heat without forced ventilation inside a space with 3 walls and a ceiling only 20 feet above the test bank. We all predicted it would get ridiculously hot, except the guy telling the riggers where to put it. "It'll be fine" said the "engineer" who never held a wrench in his life. Needless to say, future load tests were performed on a topside deck.

Also, always figure-8 the extra load cable length unless your want to repaint the hull from induction heating burning off the paint.

Interesting as fuck. Overloading the gen to calibrate a breaker? What? And the load bank thing sounds super idiotic. Also, figure 8 the extra cable? Never heard of that. My company, when training, just says never have loops in the cable when load banking.

[ - ] oyveyo 2 points 1.7 yearsSep 27, 2023 20:46:35 ago (+2/-0)*

The breakers are all electronic, some military equipment has a "battle-short" mode in which the equipment is overdriven for emergency purposes. During the test, setpoints are made in the breaker controller. This was the first of five gensets on the prototype ship to be lit-off, and they needed a real-world base reading throughout the ship's load center network to set the rest by.

If you drop your extra load cable in a figure 8 the fields mostly cancel each other out and induction heating is drastically reduced... they re-use the cables in other tests so they don't like cutting excess length off because those cables are very expensive.
