Application of Rotary Drum Dryer at Ombilin Coal Fired Power Plant

Mujammil Asdhiyoga Rahmanta and Muhammad Iqbal Felani
Abstract—PLN as State-Owned Company of Indonesia has 10.000 MW fast track projects of Coal Fired Power Plant (CFPP) which is designed for using Medium Rank Coal (MRC). PLN has not got MRC due to government policy of trading of coal. While Indonesia has a lot of Low Rank Coal (LRC) reserves nowadays. Ombilin CFPP 2X100 MW has used rotary drum dryer to increase High Heating Value (HHV) of LRC by reducing total moisture of water in coal. Rotary drum dryer uses flue gas from its furnace as heat source. Rotating test in various speeds is used to know the characteristic product (fixed carbon, total moisture, and HHV) of rotary drum dryer at Ombilin CFPP. The temperature of flue gas (heat source), the type of coal input, and the other operation parameters are maintained approximately constant when speed is adjusted.

Index Terms—High heating value, rotary drum dryer, rotating speed, total moisture.
