Abstract

Abstract Biomass is a potential biofuel which may help fighting high carbon dioxide emissions and negative impacts of global warming. Analysis of Norway spruce (Picea abies) and barley (Hordeum vulgare) were performed at the laboratory of Czech University of Life Sciences. Material was torrefied in an inert nitrogen atmosphere at the temperatures of 250 °C and 280 °C for 45 minutes. Elementary and stoichiometric parameters were monitored and impact of torrefaction and pellet production on carbon footprint was determined. Torrefied and pelleted material showed better fuel properties in comparison to the original material. Calorific value of the torrefied spruce wood chip increased by 12.27% when torrefied at the temperature of 250 °C, and by 25.41% when torrefied at the temperature of 280 °C.

受球团生产和托雷影响的云杉和大麦元素及化学计量分析

摘要生物质是一种潜在的生物燃料，可能有助于对抗高二氧化碳排放和全球变暖的负面影响。在捷克生命科学大学的实验室对挪威云杉（Picea abies）和大麦（Hordeum vulgare）进行了分析。将材料在250°C和280°C的惰性氮气气氛中烘干45分钟。监测了基本参数和化学计量参数，并确定了焙烧和球团生产对碳足迹的影响。与原始材料相比，托雷和颗粒材料显示出更好的燃料性能。在250°C的温度下烘烤，云杉木屑的热值增加了12.27%，在280°C的条件下烘烤，热值增加了25.41%。
