STATISTIC DATA ON THE HVAC - HVAC&R MARKET IN EUROPE, MIDDLE-EAST AND AFRICA

BIOMASS ENERGY

Metric tonne charcoal = 30 GJ (= 12,800 Btu/lb) (but usually derived from 6-12 t air-dry wood, i.e. 90-180 GJ original energy content)

Metric tonne ethanol = 7.94 petroleum barrels = 1262 liters

  • ­ ethanol energy content
  • ­ Lower heating value = 11,500 Btu/lb = 75,700 Btu/gallon = 26.7 GJ/t = 21.1 MJ/liter
  • ­ Higher heating value = 84,000 Btu/gallon = 89 MJ/gallon = 23.4 MJ/liter
  • ­ ethanol density (average) = 0.79 g/ml ( = metric tonnes/m3)

Metric tonne biodiesel = 37.8 GJ (33.3 - 35.7 MJ/liter)

  • ­ biodiesel density (average) = 0.88 g/ml ( = metric tonnes/m3)
