I just ordered a washing machine for the new place. I look forward to being able to clean clothes once more, does this make me sad\an adult? I'm also taking a trip up North to eat lots of burgers this weekend.

The Locator posted:So awesome. Out here in the middle of the desert, we don't have handy lakes to provide cooling water for the power plants, which made me wonder - how does the power plant cooling affect the lake? Is the temperature increase significant enough to change the ecosystem, or is it a large enough heat-sink that it has a negligible effect? Just asked one of my mentors about this after I had a semi-related question. One of the units has both the giant lakewater condenser in the previous set of photos, and two ~10,000 gallon shell & tube heat exchangers acting as condensers in parallel. I asked why they would need this, and he says the lake is too small and heats up too fast to just use the lakewater as a cooling agent. They had to tack on the exchangers and some small cooling towers, which is the way you normally do it without a large body of water. Apparently the inlet and outlet temps on the lakewater condenser have a differential of around 15°F, and can and will heat all or part of the lake, depending on its size. Anywho, as promised, a couple pics of the turbine room: Here's the low pressure turbines:  The steam runs into the High pressure, then intermediate pressure, then low pressure turbines, then goes straight down into the condenser located on the lower level. At certain points, a small portion of steam will be extracted to preheat the feedwater at the feedwater heaters in the previous set of pictures. This is a weird setup where the HP and IP turbines are on one generator, and the LP turbines are on a second generator. Here's a view of the HP and IP turbines on the left, and the LP turbines on the right:  The steam crossover is the big pipe above them. The non-piped "huts" in the foreground are the two electrical generators, connected directly via shaft. Here's a nameplate off ONE of the generators:  Remember, there's two of them. Per unit.  VVVV Naw, as long as no company names are on things I can use photos for educational stuff. They've let me use them for classes where they're teaching related stuff! I think it's mainly because it's very very old tech. If you look at that nameplate, the turbines were built in 1965. Adiabatic fucked around with this message at 13:47 on Sep 24, 2015 |

My little brother is a nuke on the Eisenhower and they just replaced the reactors and had to take it out for a test ride. They were doing hard turns at 34 knots to make sure the hull where they had to cut the holes was sound. I had no idea a ship that big could go that fast, goddamn.

For those who don't know what the gently caress you are looking at, here's a good guide: Fart Pipe posted:My little brother is a nuke on the Eisenhower and they just replaced the reactors and had to take it out for a test ride. They were doing hard turns at 34 knots to make sure the hull where they had to cut the holes was sound. I had no idea a ship that big could go that fast, goddamn. Yeah, the reactors they have on subs are phenomenal and are much more modular and smaller:  This is NOT an A4W, pretty sure, but its along the same design lines. And the Eisenhower has 4 of them.

So the VW legally should be at 0.05 g/mile in the US, 0.12g/mile it's actually at about 2.2 g/mile. My 7.3 with no emissions equipment whatsoever is only at about 5.9g/mile. What's interesting is how this killed platinum prices, because the platinum catalyst used in a high NOx DPF system is basically useless now.

Because they were not modeled on CARB which, like was mentioned in the VW thread, was modeled to treat a condition unique to Los Angeles and then applied to the EPA standards for all US vehicles.

Seriously though it's neat how many parallels there are. We have "Over-fire air" systems that parallel secondary air injection, and ammonia injection that parallels urea injection. DPFs can be likened to scrubbers and baghouses. SCRs are the catalytic converters of a coal plant. NEAT Adiabatic fucked around with this message at 16:39 on Sep 24, 2015 |
