  • Page 28: Definition Of Calorific Value

    BMA-2 Operating Manual Definition of calorific value The calorific value, or heating value, is a physical quantity that indicates how much heat is released when a particular fuel is burned. They are usually measured in units such as kilojoules per kilogram (kJ/kg) or megajoules per cubic meter (MJ/m³).
  • Page 29 The humimeter BMA-2 determines the water content in the material and corrects the calorific value from the literature by the water content contained. This means that the humimeter BMA-2 calculates the corrected calorific value on the basis of the water content and the determined bulk density and outputs this calorific value in the unit MJ/ m³.
  • Page 30 10.8% » and a bulk density of 245kg/m³. From this, your humimeter BMA-2 calculates an adequate estimate of the calorific value of 4161MJ/m³. Conversion to MJ/kg: 4161 MJ/m³ divided by 245kg/m³ (Schüttdichte) Conversion to kWh/m³:...

  • Page 38: Notes For The Measurement Of Wood Shavings

    For determining the bulk density according to norm EN 14961 a round bucket is used. As the humimeter BMA-2 device uses a rectangular measuring chamber, a compensa- tion factor is stored in the device. This compensation factor has been optimised for wood chips and therefore can differ when measuring other material types.
