We used to burn it where I worked years ago. It had to be delivered hot
(IIRC, about 125) in order to drain from the tanker truck. We'd start the
boilers on #2 oil and a steam probe from the boiler into an intermediate
tank heated it to a pumpable oil. Another pump circulated that back into
the 10,000 gallon #6 tank to keep it warm. More difficult to burn, it was
much cheaper to buy and has a higher Btu per gallon compared to #2.
The major hospitals and universities in downtown Halifax burn Bunker
C, as does the Tuft's Cove GS located on the Dartmouth side of the
harbour. Our natural gas distributor is currently extending its
pipeline into the downtown core to serve these loads, so thankfully, a
little less of this crap will make its way up the stack.
Unfortunately, the situation with Nova Scotia Power wouldn't likely
change anytime soon, as the utility prefers to sell off its allotment
of natural gas to New England and thereby pocket the difference in the
cost of these two fuels (personally, I wouldn't mind paying a little
more for cleaner air, but obviously opinions differ).
I had a summer job in an oil refinery, testing products in the lab.
I don't think that refinery produced any bunker C, it all either
went into asphalt (at the time, this refinery produced 85% of Ontario's
road building asphalt, plus specialty asphalts/tars) or further processing
for lube oil base stocks (at the time the most advanced lube production
facility in North America).

It's a whole lot more complicated than that... :)
"...multifunctional diesel fuel additive packages are built around ...
dispersant/detergent technology which meets the requirements for
...injector cleanliness. ... The detergent can be combined with other
functional components such as lubricity improver, cold flow improver,
deicer, cetane improver, corrosion inhibitor and/or demulsifier to
deliver additional benefits..."
W/O the additional lubricity specifically, no modern diesel engine will
last long and the injector-cleanliness requirements as well as S limits
on road-fuels are significant factors. Underneath, yes, it's "fuel
oil", but the engine-diesel is far more sophisticated a product.
I didn't want to get into it that deep but what you wrote is accurate.
My buddy has a liquid fuels business and he often tells me of all of the
hassles of keeping track of all of this and the multiple trips his
trucks have to run for the separate products.
It is done much differently. They don't blend the oil and offer "heating
oil" except at point of delivery if that is what you specify. They sell
#1 or #2 for home use and if they have never delivered to you they will
ask if you have an outside tank. If so they will flag your account as
I knew some folks years ago, who often ran out of fuel oil. They were upset
that the water heater didn't work dependably, so they replaced it. Instead
of having the oil tank filled. They were idiots, for sure. I poured a lot of
five galon cans of diesel or kero into their tank for a while.
Not necessarily. Sometimes it's #2 diesel. Sometimes
it's a mix of the two. And sometimes it's #2 with
additives to keep it from getting thick a colder temps.
(One effect of the above is that if you buy heating oil
in bulk it is *essential* to make sure the supplier is
aware that fuel bought in the summer will be stored and
used in the winter. Otherwise it is possible to get a
great deal on "summer grade" stove oil, and have a tank
full of jelly come cold weather.)
Moreover, Both #1 and #2 "diesel" are regionally
defined, with each refinery deciding exactly what they
will sell under those names.

Our local dealers (Halifax, N.S.) stopped offering #1 three or four
years ago and this caused problems for folks with oil stoves/space
heaters; in most cases, a simple carburetor adjustment did the trick,
but in a few instances, homeowners were completely out of luck.
Interestingly, low sulphur heating oil may offer superior
low-temperature performance; to whit:
".... Don Allen, Jr., President of E.T. Lawson, says his technicians
are discovering clear evidence that the amount of scaling in low
sulfur-burning furnaces is comparatively less than systems used with
regular #2 oil. The corporation is so convinced of low sulfur oil
advantages that it guarantees that the oil will not gel, wax, ice, or
sludge; otherwise, the company promises to clean the entire heating
system for free and refund the cost of the tune-up...."
Delivery slip says #2
When I was in Italy it was common to use diesel in home heating burners.
Sells for the same high price as heating oil. In mild climates people can
buy five or ten gallons at a time that way.
