SOLID PARTICLE CARRYING METHOD AND CARRYING SYSTEM
FIG1 is a schematic diagram showing an example of a conveying system that is suitably used for a conveying method of the present invention 
Hereinafter, the conveying method and the conveying system will be described in more detail with reference to FIG1 related to the conveying system 10 of solid particles. The conveying system 10 shown in FIG1 includes a delivering means 21 to which solid particles that are to be conveyed have been introduced and that supplies the solid particles to a conveying path 24, the conveying path 24 that is connected to the delivering means 21 and that conveys the solid particles supplied from the delivering means 21, a receiving means 20 that is connected to the conveying path 24 and receives the solid particles from the conveying path 24, and a solid particle supply path 23 that supplies the solid particles to the delivering means 21. Furthermore, as shown in FIG1, the system 10 is preferably such that the gas returning path 26 and the conveying path 24 are connected to each other via a detour path 27 detouring around the delivering means 21. The detour path 27 is connected to each of the gas returning path 26 and the conveying path 24 near the delivering means 21. The portion of the gas returning path 26 between the point connected to the detour path 27 and the delivering means 21 (hereinafter, also referred to as a "first branch portion") 26a, and the portion of the conveying path 24 between the point connected to the detour path 27 and the delivering means 21 (hereinafter, also referred to as a "second branch portion") 24a are respectively provided with valves 26b and 24b. Furthermore, the detour path 27 is also provided with a valve 27b. With these valves, the first branch portion 26a, the second branch portion 24a, and the detour path 27 can be opened and closed independently of each other. Furthermore, if the detour path 27 is provided, it is preferable to use a pressure-feeding blower as the blower 22. The conveying system 10 shown in FIG1 was used. The environment was at an ambient temperature of 10°C.
