Fuel oil piping layout
Fuel oil piping layout
(OP)
Hi, what's a good reference (online or off) for boiler fuel oil piping layout. Mainly I need to know when it's ok to use only burner mounted pumps without a recirculating loop. I've read ASHRAE fundamentals and it just gives you pipe sizing & a recirculating system schematic. I would prefer a more detailed explaination of both methods. Thanks.

Normally they tell you if it is possible to use burner pump only. It is dependant of lenght of piping, heigt difference between oil tank and burner and is generally applicable for one-burner layout. (I know the solution where you run piping for two burners separataly from tank - separate connections for piping even at the tank flange - where you don't have to use the additional pump.)
Seek manufacturer documentation while selecting burner(s)!

Drazen is correct. You can also run dedicated supply & return to & from each boiler burner pump instead of a single recirculation loop.
Another thing. Diesel is different from No. 2 fuel oil. Diesel has antiknock additives. So if you have diesel generators they need a diesel fuel & tank system, separate from the fuel oil system.
New underground systems use double wall flexible fuel oil piping (available up to 2.5" size). This is less expensive & more reliable than steel pipe within PVC conduit.

I have run into that problem and have tried to ascertain how to convince the owner that although they are very similar, they are not the same.
How would that be accomplished?

It is possible to get antiknock additives to No. 2 fuel oil however this require good record keeping & fuel usage measurment to be effective.
