Some random comments on reddit about Russian aircraft carrier Admiral Kuznetsov in the English Channel off Dover on Oct 21st 2016 [2048x1909]
- Yeah, even at a decent speed she is putting out smoke. Coal powered?
- Bunker fuel. the sludge left over once you've refined everything else useful out of oil. Not the cleanest or most efficient fuel, but it's cheap and burning it in ships solves the problem of what the hell to do with the stuff at the end of the refining process.
- Hey Bob, what do we do with this dirty hsit no one else wants? Don't know Jerry. What if we sold it for use in ships so when that foul stuff is burned and puts out that horrific looking smoke, it's done at sea where no one will notice? Sounds good to me Bob. Lunch?
- Bunker fuel is a semi-solid. It's basically tar. You have to preheat it to get it to flow.
- As a docent on the Hornet said in an engine room tour, "When it was cold, you could shovel it faster than you could pump it."
- How would you like to be assigned to that engineering plant? Not on your life. Probably a maintenance nightmare.
- Probably a maintenance nightmare. Considering how often it breaks, requiring an oceangoing tug to tow the ship home [ 1 ], there's no "probably" about it
- A lot of used motor oil gets sold as bunker fuel. I guess you can call it "recycling". Some environmentalists don't like the practice but it is the best way of disposing of the stuff I can think of. Better than dumping it somewhere or having it sit in rusting metal drums in a toxic waste dump somewhere.
- Why wouldn't they just use refined fuel instead of refining it on-board?
- They don't refine it on board, they just heat up the fuel tank a bit (no where near flammable temp) to get the thick oil flowing. It's then pumped through a pipe system where it "sprays" out into a burn-box & heats up the water inside the boiler tank. The reason they use bunker oil is that it's stupid cheap.... if you have a 300,000 gallon gas tank, you want cheap fuel. Also, in war time, you can get bunker oil just about anywhere in the world since it's so hsit quality, there's no real worry if you get it from Syria, Venezuela, Cuba... whatever.
- OMG I saw a meme the other day about this same ship being coal fired and I cant for the life of me find it.
- This one?
- That first pic reminds me of this well known photo of a British carrier damaged by kamikaze.
- That looks like she's venting steam, either intentionally to get pressure down or as a result of battle damage.
- That is not steam, that is fire.
