| Popis: | The exhaust heat of steam power plant has considerable energy potential that can be recovered for various processes, one of which is for the drying of materials. The purpose of this research is to know the performance of a copra dryer by utilizing exhaust heat from coconut shell charcoal fired power plant which has been developed by P3TKEBTKE. Copra dyers consisting of a fan, heat exchangers, and a drying chamber are installed on the boiler combustion flue gas duct as the heat source. This research was conducted by varying fan speed at 2.2 m/s and 3.7 m/s. The results show the drying room temperature between 36-130°C, are not equally distributed. The test results with the air flow rate of 4.14 m3/m shows the average temperature of 72.18°C drying copra final moisture content 17.72%, the drying rate of 4.72%, energy consumed 55.97 MJ/kg, thermal efficiency 20,90% and drying efficiency of 4.83%. While the test results with an air floe rate of 6.97 m3/m shows better results with an average temperature of 68.13°C drying copra final moisture content 16.05%, the drying rate of 5.1%, energy consumed 32.47 MJ/kg, thermal efficiency 55.57% and drying efficiency of 8,25%.. |
