In a gas flow-using powdery and granular material fluidization transporting method and apparatus using airflow, an apparatus is provided to feed out powdery and granular material into a transporting tube provided for pneumatically transporting the powdery and granular material. The feeding out apparatus includes intracontainer-pressure means (23a, 23b) for detecting the pressure in a storage container, intra-transporting tube-pressure detecting means (25a, 25b), and pressurized-gas regulating means (17a). In addition, a plurality of discharging ports is provided, and transporting tubes are individually connected with the discharging ports. The discharging ports and transporting tubes are selectively used to pneumatically transfer the powdery and granular material. Moreover, steps of detecting a clogging and taking countermeasures against it are provided. In a blowing method, a high-temperature gas is used, and the amount of a carrier gas is regulated. Furthermore, a distributor is provided for a transfer passageway to allow control to be securely implemented for distribution of the powdery and granular material into a plurality of transfer passageways. Concurrently, a static-electricity generation state is monitored to provide countermeasures against cloggings that can occur in the transfer passageways. <IMAGE>
