Abstract

This research was devoted to design an unfired brick solar furnace, heated and powered using solar energy. Mathematical model was developed to predict the configuration and performance of a system consisting of several components to produce geopolymer bricks. A computer program by using JavaScript consisting of a main routing and three subroutines was developed. The sizes of the solar collector and of solar panel are the performance of the interior heat exchangers. The temperature of the bricks was predicted. Error analysis techniques are used to validate the predicted results versus the measured values. The predicted results show good agreement with the measured values (R² = 0.9823). Also, the output results indicated directly the heating load required inside the solar furnace to dry the unfired brick with a designed interior air temperature at 100˚C range between maximum heating load required "916.72 Watt" at midnight and the minimum value "810 Watt" at near noon. Output results of the computer models were used afterwards for design and construct the solar furnace system for curing unfired bricks.
