Wood that has been air dried to 20% moisture has a net heating value
of 10,560,000 BTU/ton, whereas green wood at 50% moisture has a net heating value
of 5,740,000 BTU/ ton.
3% net heating value of ethanol relative to that of RO, 36.
3%) net heating value of petrol, bsfc under heavy loads, [lambda] = 1.
In spite of better atomization of heavy oil droplets and an extra amount of ethanol oxygen available for the complete combustion of fuel-rich portions, a lower cetane number and net heating value of ethanol remain the main cause as to why a loaded engine running on oxygenated RO blends does not operate efficiently at speeds of 2000-2200 [min.
Comparing with blends ERO, the addition to petrol utilises advantages related to a three-fold higher cetane number and excellent miscibility with RO that along with its wider evaporation range, lower auto-ignition temperature and better net heating value results into the bsfc of the engine running on blend PRO2.
To evaluate the energy conversion of blends ERO and PRO, the following factors including biofuel mass consumption, the net heating value of RO and both improving agents as well as their blending ratios and biofuel oxygen contents were taken into account.
8vol% of oxygen and oil mixing with ethanol diminish the net heating value of the blend that at higher ethanol additions may affect the emission of N[O.
5, better atomisation of heavy RO droplets and a higher net heating value of petrol stimulates combustion.
3]) and their net heating values also differ from 26.
Due to the addition of more calorific petrol in RO, the net heating values of blends PRO2.
