Granulated biofuels combustion efficiency

IOP Conference Series: Earth and Environmental Science, 2019
Abstract The article presents the results of experimental studies of the thermal and ecological performance of the Firematic 60 boiler manufactured by Herz Energietechnik GmbH. Wood pellets with diameter of 6 and 8 mm and biochar from hydrolytic lignin were used for combustion. The components of the boiler’s heat balance and the emission
