PROBLEM TO BE SOLVED: To provide a solid fuel crushing supply device and a method, capable of maximally forming a facility of an air carrying system to a boiler of solid fuel such as biomass and coal in a small scale. SOLUTION: A biomass carrying fan 5 is arranged in a system of a mill 3 of the biomass in a system for inputting fuel to the boiler by supplying carrying air of the coal finely crushed by a coal mill 7 from a PAF 13, by supplying combustion air from an FDF 11. The finely crushed biomass is carried by the air, and fine powder solid fuel is separated and collected by a cyclone 4, and the air is introduced as it is to a front flow of an air preheater 12 of the boiler, and is mixed with the combustion air from the FDF11, and is supplied to a burner 9, and is used as the combustion air. Fine powder biomass collected by the cyclone 4 is inputted to a coal feeder 6, and afterwards, a mixing rate quantity with the coal is uniformed by being supplied in the mill 7 simultaneously with the coal. Fan motive power such as the FDF11 can be reduced by using the air used for carrying the fine powder biomass as the combustion air. COPYRIGHT: (C)2009,JPO&INPIT
