Abstract

Abstract A system for and method of producing a beneficiated fuel from a moisture ladened fuel. A combustion turbine is operated to provide a flow of exhaust gas out of an exhaust outlet at a temperature above ambient. The flow of exhaust gas is then directed across the moisture ladened fuel such that a portion of the moisture carried by the moisture ladened fuel is removed to produce the beneficiated fuel.
