While I used to do calculations well, and even in my head, I now need some help.
I'm trying to calculate fuel usage in an oil fired 2x6. If I RO to 8% sugar I should get 1 gal of syrup from 11 gal of concentrate
(the updated rule of 86, now using 88). I'm going to calculate 50 gph evaporation and 4 gal of fuel consumed in that hour, I should get 1.13 gal of syrup for each gal of fuel burned. Now, if my sap started at 2% sugar I'd be boiling off 4.54 gal worth of sap for each gal of fuel burned x4 (2% to 8%) means I'd turn 18 gal of raw sap into 4.5 gal of syrup an hour. At that rate 35 hrs of boiling would convert 630 gal of sap into 35 gal of syrup. Have I somehow screwed the calculation up thus far?
Now if I RO to 12%, (2 passes) I get the same amount of syrup from the sap but use 1/3 less fuel to do it. Thus I could turn about 940 gal of sap into syrup using 140 gal of fuel. Do you see an error in my calculations?
