Prediction of higher heating value of oat grain and straw biomass

Abstract

The aim of the study was modelling of HHV of oat (grain and straw) biomass. The content of ash, carbon, hydrogen, nitrogen, moisture, volatile materials and the higher heating value of oat (grain and straw) biomass was measured. The possibility of using twenty models from the literature to describe HHV of oat was examined. The following models: HHV=19.914-0.2324A and HHV=-3.0368+0.2218VM+0.2601FC are recommended for determining of HHV of oat (RMSE of the range 0.13-0.28). The models based on ultimate analysis gave worse results in determination of HHV for oat.
