Biomass Energy Foundation: Proximate/Ultimate Analysis

PROXIMATE AND ULTIMATE ANALYSES. Biomass fuels are characterized by what is called the "Proximate and Ultimate analyses". The "proximate" analysis gives moisture content, volatile content (when heated to 950 C), the free carbon remaining at that point, the ash (mineral) in the sample and the high heating value (HHV) based on the complete combustion of the sample to carbon dioxide and .
