Abstract
The goal of the work was to propose and verify the model of temperature changes of the convective dried biomass depending on the drying time. The algebraic temperature model of the convective dried solid, giving the possibility of its direct calculation, was based on the logistic function of growth. Temperature model was verified for convective dried biomass: vegetable and wood (poplar and willow wood chips) significantly differing in initial moisture content. Parameter W in the temperature model, defined as the coefficient of temperature rate changes reaches greater values in higher temperature of drying air and for wood biomass which has lower initial moisture content. Empirically selected parameter W allows to verify the temperature model with the relative error less than 5%.
Highlights
Biomass is third largest and most available natural source of energy, and is widely used in power industry [1,2,3]
Biomass types suitable for energy purposes include wood biomass and plant-derived biomass that does not meet quality requirements for raw materials to be used as food or fodder, e.g. infected grain, fermenting or moulded pomace left over from the production of fruit or vegetable juices left for too long before processing, etc
In case of bodies with the moisture ranging from 30 to 50% and bodies with high moisture content that initially dry in the first and in the second period of drying, e.g. fruit-vegetable biomass, with the moisture content higher than 50% that take a long time to heat to the temperature of the drying agent due to their material structure, such an assumption is a large simplification of the characteristic of continuous change of the temperature of the material being dried
Summary
Biomass is third largest and most available natural source of energy, and is widely used in power industry [1,2,3]. Biomass types suitable for energy purposes include wood biomass and plant-derived biomass that does not meet quality requirements for raw materials to be used as food or fodder, e.g. infected grain, fermenting or moulded pomace left over from the production of fruit or vegetable juices left for too long before processing, etc. In most cases, such biomass requires drying to obtain the desired combustion parameters and the required energy value of the fuel [6,7]. Predicting this process based on mathematical models of their computer simulations is recommended
