Abstract
The paper presents experimental data obtained in the course of investigation focused on analysis of thermo-physical properties of baled biomass which value are necessary for modeling of transport phenomena in materials with porous bed. Experiments were conducted using a custom designed and constructed experimental setup and implementing original experimental procedure. Results obtained enabled stagnant thermal conductivity of biomass to be determined for different biomass porosity values. Analysis of experimental data enabled functional dependence of stagnant thermal conductivity on porosity to be determined, with porosity varied in a range 0.50-0.85. Results obtained indicate that reduced bed porosity, down to the value of 0.65, causes stagnant thermal conductivity of the bed to be reduced. Further porosity reduction, below the value of 0.65, results in increased stagnant thermal conductivity of the bed. In addition, data to be acquired shall be helpful in modeling the transport phenomena associated with combustion in porous beds.
