Yes you can although B100 has less engery per gallon than #2 B100=127,000btu/gal #2=131,000btu/gal

That would about right for ruff gross heating values but what we actually see and use is net heating values that has lower BTU's mostly from water content and the crude oil soruce.

The location of the source has a huge roll in determining net BTU's per gallon wheather it be dino oil or vegetable oil.

Example: From my combustion engineers handbook for gross BTU/lb

#2 Alaska crude= 18470btu/lb
#2 MiddleEast crude= 19070btu/lb
#2 Venezuela crude= 18400btu/lb

Clean #2D contains about 500ppm of water contained with-in the fuel.

Clean B100 contains about 1500ppm of water contained with-in the fuel.

Both quotes from ASTM standards.

And while ASTM does say that 500 ppm of water in #2 and 1500 ppm in Bio is acceptable, that does not mean that there is any. Do not confuse acceptable standards with actual results.

Indeed if your designing combustion equipment you very well use net BTU values or you will underdesign the equipment.

Using your example, you would need to eat 1-1/2 candy bars if the total requirement was 300 calories needed as the net calories of the candy bar was only 200 net calories per candy bar for whatever reason. 1.5x200=300

As soon as any oil gets exposed to the atmosphere it starts gathering moisture content.
