| description | Woodchip sampling may be done according to two methodologies, based on the volume or calorific value of the fuel. The paper compares heating values obtained through relative humidity measurements according to Slovak technical standards and through determination of calorific value according to the ISO 1928:2003 Standard. The aim is to compare values obtained by both methods from a selection set and to determine possible reasons in case various values are obtained. Based on the results obtained it may be confirmed that differences between the heating value calculated according to the ISO 1928:2003 Standard and according to the STN 48 0057 (2004) and STN 48 0058 (2004) Standards are statistically significant. The average difference in heating value is 0.629 MJ.kg-1. |
