Abstract
Low Rank Coal (LRC) such as Lignite and Sub-bituminous coal is the main fuel for power generation in Indonesia, because LRC is huge abundant resources in Indonesia and its price is lower than bituminous coal. Meanwhoil, CO2 emission volume per kWh of LRC is higher than bituminous coal. Pre-drying of LRC by integration Steam Tube Dryer (STD), indirect steam heating dryer, and steam system of power plant allows coal power plant to reduce LRC consumption and CO2 emission.
