Abstract

The present invention relates to a method and apparatus for upgrading low-rank coal, which upgrade low-rank coal, having a water content of 30% or more, into coal for generating power and having a water content of 10% or less and a calorific value of 6,500 kcal/kg or more, through the use of heavy oil ash and a microwave drying process, which prevents the spontaneous combustion of the coal upgraded into high-rank coal.
