[Digestion] Sulphur levels

[Hoysall Chanakya]

Biogas Friends

Just a small correction to this train of thought
BURNING Vs FERMENTATION - THE NEVER ENDING DEBATE

Measured Cal value of dry dung = 3100kCals/kg
Conversion of wet dung at 18% moisture = 40L/kg @60% methane

This works out to (0.040 X 5500kCals/m3) ÷ 0.18 (correction for moisture)
 = 1222kCal (or about 40% energy recovery efficiency

I am not so sure that there is a more energy efficient way to recover
energy from cattle dung.

Best wishes
Chanakya
