Webcorrelation developed by Mott and Spooner achieves the best accordance to heating values of wood and straw from statistics, i.e. measurements. Keywords: Flowsheet; Aspen; heating value; standard heat of formation; Boie; biomass 1 INTRODUCTION The engineering and planning of power, heat and fuel production plants in general bases on WebLHV = 50.025 MJ/kg The LHV is calculated assuming that water remains in the gas phase. However, more energy can be extracted from the mixture if this water is condensed. This value is the higher heating value (HHV). The ideal gas mixture model used here cannot calculate this contribution directly.

The higher heating value (HHV; gross energy, upper heating value, gross calorific value GCV, or higher calorific value; HCV) indicates the upper limit of the available thermal energy produced by a complete combustion of fuel. It is measured as a unit of energy per unit mass or volume of substance.
