HappyGA

#3 could exist but is used rarely.
Viscosity grade usually jumps from #2 to #4 then to #6
These heavier fuels are mostly used on ships or large institutional oil fired furnaces.
#6 is almost like tar and has to be heated in order to flow.

I used to be a tanker-yanker and I think it was #5 I hauled to the sugar plant by Goodrich Ks. It was black and syrupy! Craig

We have 2 boilers at work, they will burn either natural gas or #6 oil, which ever is cheaper. #6 is like tar at ambient temp. You have to heat it, just to be able to pump it. It is some nasty stuff.

Number three is fuel oil.

Lots of older homes still use it to heat with.


As mentioned above number 5 and 6 is thick like tar.

Most steam and hot water boilers runs off of # 5 fuel oil.

The tanks have unit heaters in them to "loosen" it up a little before pumping.

Goodrich Ks. There are 10 homes (21people) and a RR track in Goodrich, Kansas! Where is the sugar plant? Must be Parker, or Centerville!!!!

It was over 30 years ago. Not far from the state line into Ks coming from the Denver side. I'm not sure about the name of the town (might have been Caruso) but I thought it was close to Goodrich. It might be gone by now. A lot of sugar plants have closed. My BIL works at the plant at Ft Morgan. Their boilers are coal fired. The coal train runs next to the bldg and the coal goes straight from the car and into the stokers. Craig
