Ash Content vs. the Economics of Using Wood Chips for Energy: Model Based on Data from Central Europe

Popis výsledku v původním jazyce

Biomass utilization is vital for developing sustainability in the bioenergy sector. In this work the effects of high ash content on the heating properties of wood chips were evaluated. In an analysis of 450 wood chips samples, the ash content, moisture content, and gross calorific value were determined, and a generalized linear model was created to identify the relationship between the gross calorific value and the ash content of the wood chips. The mean ash content of the analyzed wood chips samples was 2,64%, the mean moisture content was 38,8%, and the mean gross calorific value was 19,43 MJ kg(-1). Statistical analyses showed that 49% of the gross calorific value variability was due to the ash content variability. A one percent increase in ash content resulted in a 0,11 MJ kg(-1) decrease of gross calorific value. The estimated costs of ash disposal at various ash contents were calculated. Burning wood chips with 5% ash content would lead to depositing an extra 5,6 megatons in the US or 21,2 mega
