Transformation of the mineral matter of fuel wood in thermochemical conversion processes

Resumo

The mechanism of the formation of ash deposits on the internal surfaces of equipment during the thermochemical conversion of wood biomass was investigated. It was shown that the transfer of the mineral matter of fuel wood through a gas phase is the prevailing mechanism. The thermodynamic calculation of the equilibrium concentrations of the main mineral matter components in the gas phase was performed with and without consideration for the organic matter of fuel. The atomic absorption analysis and thermal analysis of the mineral matter of wood was carried out.
