SIMULATION OF THE HIGH-TEMPERATURE DRYING OF A COMPOSITE MIXTURE IN AN AIR DRIER FOR PRODUCTION OF A BIOCOMBUSTIBLE

A mathematical model is proposed for defi ning the high-temperature drying of a composite mixture comprising a peat and a vegetable biomass in an air drier with the use of equations for the kinetics of drying of the individual components of the mixture and the dynamics of their movement, in which the infl uence of the initial moisture contents of the mixture components and the parameters of the drying agent (its temperature, moisture content, and fl ow velocity) on the kinetics of drying of particles of the composite and the disperse phase is taken into account. It is shown that the kinetics of drying of the indicated mixture is determined by the properties of its fractions, the composition of the mixture as a whole, the stages of its milling, the content of the disperse phase in the drying agent, and the velocity of the drying-agent fl ow. The mathematical model proposed can be used for the intensifi cation and optimization of the working regimes of air driers.
