Fuel oil vs Bunker C

[normhart]

With the new availability of ANL's Union Pacific assets and the NARM's new FEFs the need for refueling these arises.

Is Fuel Oil the same as Bunker C?

<kuid2:103021:60000:2> Fuel Oil by lilb
<kuid2:30671:9271390:2> Bunker c oil by llj

I haven't found any industries that use Fuel Oil, and only a few railcars that use it. ANL tenders use this as do lilb's SP tenders although not ANLs oil turbines oddly

There are a few of Bunker c oil industries, 3 track only PL, BI and BI2 industries by llj and a couple of others

<kuid2:124060:28008:4> Oil tank by Pencil42

that I know of. Pencil42's is unsuited for the big modern locomotives but Ben's Rose Oil Column is pretty cool and nicely animated although I haven't tried it out with our new stuff yet. It needs a storage tank paired with it though and I have no idea if we have suitable Bunker C storage tanks. I didn't see anything specific on the DLS.

There are a ton of tanker cars and tenders that use Bunker C. including NARMs FEF tenders.

I don't know of any routes that have bunker c or fuel oil refueling points set up.

Any thoughts, suggestions?

I've been using the Cheyenne facility since the BI2 tracks are configurable for Bunker C but they don't resemble a Bunker C facility IMO.



Especially since a single tender could drain most of those tanks.

Is Fuel Oil the same as Bunker C?

Depends....

The USA has 6 grades of Fuel oil, #1-#6.

From Wikipedia....google search is your friend.

Number 1 fuel oil is a volatile distillate oil intended for vaporizing pot-type burners.[SUP][3][/SUP] It is the kerosene refinery cut that boils off immediately after the heavy naphtha cut used for gasoline. Former names include: coal oil, stove oil and range oil.[SUP][2][/SUP]

Number 2 fuel oil is a distillate home heating oil.[SUP][3][/SUP] This fuel is sometimes known as Bunker A. Trucks and some cars use similar diesel fuel with a cetane number limit describing the ignition quality of the fuel. Both are typically obtained from the light gas oil cut. Gas oil refers to the original use of this fraction in the late 19th and early 20th centuries – the gas oil cut was used as an enriching agent for carburetted water gas manufacture.[SUP][2][/SUP]

Number 3 fuel oil was a distillate oil for burners requiring low-viscosity fuel. ASTM merged this grade into the number 2 specification, and the term has been rarely used since the mid-20th century.[SUP][3]
[/SUP]
Number 4 fuel oil is a commercial heating oil for burner installations not equipped with preheaters.[SUP][3][/SUP] It may be obtained from the heavy gas oil cut.[SUP][2]
[/SUP]
Number 5 fuel oil is a residual-type industrial heating oil requiring preheating to 77–104 °C (171–219 °F) for proper atomization at the burners.[SUP][3][/SUP] This fuel is sometimes known as Bunker B. It may be obtained from the heavy gas oil cut,[SUP][2][/SUP] or it may be a blend of residual oil with enough number 2 oil to adjust viscosity until it can be pumped without preheating.[SUP][3][/SUP]

Number 6 fuel oil is a high-viscosity residual oil requiring preheating to 104–127 °C (219–261 °F). Residual means the material remaining after the more valuable cuts of crude oil have boiled off. The residue may contain various undesirable impurities, including 2% water and 0.5% mineral soil. This fuel may be known as residual fuel oil (RFO), by the Navy specification of Bunker C, or by the Pacific Specification of PS-400.[SUP][3]

You would have to know what Fuel Oil the industry is configured for. A look at the product might tell you.

Additional: A quick look at the industry I would guess #2 Home heating fuel oil.

OK, turns out that lilb's Fuel Oil is Number 6 fuel oil which is the same as bunker c so both commodities are the same and while there are industries that support bunker c there aren't any that support fuel oil. I was able to refuel NARMs FEFs but not ANLs using the Rose Oil Column. Looks like I'll have to build my own refueling site that handles both commodities.

Norm, the reason why the Cheyenne oil facility doesn't look lik a bunker c oil facility is because it isn't.

The Union Pacific used No. 5 fuel oil on the FEFs, Challengers, Bigboys, etc. However, I cannot say for sure for the turbines although I would wager that they also use No. 5 fuel oil.As n8phu mentioned above, No. 5 fuel oil is also known as Bunker B oil, I considered making my own No. 5 oil product asset for the FEFs however, I found that llj's bunker c oil was widely used on most assets that I have seen and that is why my FEF tenders use bunker c oil, even though it is technically the wrong fuel type.

Um hum, glad you didn't three commodities for the same locomotive would have been confusinger.

So far I've only found one picture of what may be Union Pacific fuel oil refueling

That is Council Bluffs BTW. I'm pretty sure the structure on the left is the coal tipple.

Not at all sure where the fuel oil facilities would be at Cheyenne and Laramie.

Given the close proximity at Council Bluffs one could guess that the fuel oil points would be near the coal tipples at Cheyenne and Laramie I suppose.

Something like this I guess.



Edit; Ah that's better

For what it is worth I've updated my <kuid2:633834:101171:1> BI2 Steam Locomotives Short to process Bunker C and Fuel Oil commodities. Testing indicates both tenders fuel types load OK. Should be available soon (tm).
