Resumo

The possibility of using high-frequency induction (HFI) argon plasma of atmospheric pressure for torrefaction of fuel pellets from upland peat to improve combustion efficiency has been demonstrated experimentally. From analyzing the emission spectra of argon plasma during peat surface treatment, the component composition of the plasma flux was determined. The presence of OH radicals was found to have a destructive effect on the natural polymers of peat. As a result of polymer degradation, the compacted fibrous structures forming the peat matrix acquired a loose surface. The methods of thermogravimetric analysis revealed that during pyrolysis pellets lose less mass due to the removal of volatile components during treatment in plasma, and this allows reducing emissions into the atmosphere during combustion.
