Noting that many barges and ‘big freighters’ run on “bunker” or 6-oil, I wonder if that was what Dali had in the tank.
Just something we always had on hand at the terminal in Chicago (Lake Calumet).
This one probably ran on that “bunker” or No 6 oil too. If it had been operating on liquid natural gas, there would not be a bellowing of black sooty smoke at full throttle.
That bad boy was rollin’ coal.
Ships that run on Bunker C or other heavy oils can’t use piston engines. They will always have a steam generator fired by a boiler. They would typically use some of their own spent steam to warm up the fuel tank enough to get the stuff to flow then vaporized under pressure to get it to burn. You might find crude oil carriers using that system since they can burn the stuff they’re hauling.
Table of fuel oils
No. 1 fuel oil, aka, #1 distillate, #1 diesel fuel, Kerosene, Jet fuel
No. 2 fuel oil, aka, #2 distillate, #2 diesel fuel, Road diesel, Rail diesel, Marine gas oil
No. 3 fuel oil, aka, #3 distillate, #3 diesel fuel, Marine diesel oil
No. 4 fuel oil, aka, #4 distillate, #4 residual fuel oil, Bunker A, Intermediate fuel oil
No. 5 fuel oil, aka, #5 residual fuel oil, Heavy fuel oil, Bunker B, Navy special fuel oil, Furnace fuel oil
No. 6 fuel oil, aka, #6 residual fuel oil, Heavy fuel oil, Bunker C, Marine fuel oil, Furnace fuel oil
Note: None of this is remotely as heavy as what was burned in merchants in WW2 and nothing like heavy crude we import from Venezuela. Most people would be hard pressed to tell most of these fuels apart if they saw them in glass beakers.
