| Summary: | The background idea of the current research lies directly in the evaluation of combustion performance and its association to the analysis of the quality of different types of herbaceous-based briquettes mixed with wood. In total, 25 briquette samples were prepared using different proportions of herbaceous and woody biomass. Draff, buckwheat hulls, straw, rapeseed by-product from biofuel production, oats, and common reed were used. Briquettes fully produced from wood were used as a benchmark.
A laboratory analysis was completed to determine the following parameters of the samples: moisture and ash content, calorific value, ash melting temperature, content of carbon, hydrogen, nitrogen, and sulphur. The combustion tests were executed using a heating stove for all samples. The results show that some types of non-wood biomass have a positive effect on briquette production and the combustion processes.
