Introduction Harvest residues are an important source of bioenergy. The interest in this renewable biomass lies in its local availability. Traditionally, wood is assessed on a volume (m³) or weight (odt = oven-dry tonnes, gmt = green-metric tonnes) basis although these units don’t accurately represent the value of biomass when used for energy purposes (kWh= kilowatt-hour, MWh= megawatt-hour, GJ=Giga joules). The monetary value of the biomass depends partly on its heating value which is the amount of energy that can be obtained when burning. FPJoule is able to calculate the amount of usable energy in the biomass.
What FPJoule does
  • The Energy cost section determines the amount of energy obtained when burning a given mass of residues of a certain species, type, and moisture content. A conversion tool calculates monetary equivalents (weight, volume or energy).
  • The Economic advantages section calculates annual potential savings by modifying the traditional energy supply for biomass.
  • The Fuel parameters section allows the user to view the different values used in FPJoule. The Reference section lists the information sources used in FPJoule.
  • The Report allows the user to see an overview of the analysis and to print a copy.
Inputs The user can modify all the values in FPJoule except calculated results shown in grey.
