Feasibility study of integrating solar energy into anaerobic digester reactor for improved performances using TRNSYS simulation: application Kenitra Morocco

摘要

This paper studies the feasibility of the integration of the solar thermal energy in the anaerobic digestion (AD). In this purpose, a simulation model of the digester reactor (V=70 1) coupled with a new design of the solar water thermal system has been developed using TRNSYS. The heating is carried out by an exchanger inside of the digester. The thermal performance and dynamic behaviors of the system under a climatic condition of Kenitra are investigated. It is found that the solar system covers 90 % of the energy consumed by the AD during the year. In addition, the results show a daily temperature fluctuation of 0.8 癈 in the summer and 2.3 癈 in the winter.
