Modeling of heat exchange processes in a condenser of a pyrolysis bioenergy plant
Abstract
The article presents the results of mathematical modeling of heat exchange processes in the condenser of a pyrolysis plant, in order to identify the optimal parameters for cooling the biomass pyrolysis steam. A mathematical model of the thermal balance of the condenser of a pyrolysis plant has been developed for the calculation, selection and thermal analysis of the working cycle of the condenser, which allows to obtain the values of the optimal parameters of the temperature regime. The technological scheme of a pyrolysis bioenergy plant with a recuperative heat exchanger, which simultaneously provides hot water, gaseous and liquid biofuels to the consumer, is presented. The analysis of the obtained results shows that the water temperature at the outlet of the condenser of the pyrolysis plant is on average in the range of 60-70°C and suitable for heat supply systems of an autonomous consumer.
