Interaction between Technological and Material Parameters during Densification of Selected Types of Herbaceous Biomass

Abstract

In this paper, we will present the research findings concerning relationships between technological and material variables (parameters) during densification of selected types of herbaceous biomass. In general during the biomass densification can be recognized various technological and also material variables which significantly influence the final solid biofuels quality. In case of herbaceous biomass densification there are some important differences with comparing the wooden biomass. These differences come from the material (herbaceous) composition and also from material structure and influencing also lonely treatment, densification and also the combustion of final briquettes from herbaceous biomass. The main goal of presented experimental research is to determine the relationship between compression pressure, compression temperature and raw material particle size. Experimental research described in this paper was realized by single-axis densification, which was represented by experimental pressing stand. The impact of investigated variables on the final briquettes density and briquettes dilatation was determined. Mutual interactions of these variables on final briquettes quality are showing the importance of mentioned variables during the densification process. The experimental findings presented here are significant from briquettes production point of view and also from densification machines engineering point of view.
