PROBLEM TO BE SOLVED: To dry wood at low cost in a short time, and to store coal and wood indoors in safety without causing a fire and the like. SOLUTION: This combustion system 10 is a system for mixing and burning coal and wood, and comprises a storage tank 11 for storing the coal and wood, a circulating portion 12 for extracting the coal and wood from the storage tank 11 and returning them again to the storage tank, and a boiler 13 for mixing and burning the coal and wood conveyed from the storage tank 11. The wood is dried by oxidative heat of the coal in the storage tank 11 so that an average moisture content of the wood becomes less than a prescribed value. COPYRIGHT: (C)2008,JPO&INPIT
