PROBLEM TO BE SOLVED: To perform straight piping with few bending positions for pneumatic transportation piping and attain cost reduction in transportation equipment by facilitating piping work, in a transportation equipment for powder which incorporates powder into common pneumatic transportation piping from a plurality of powder feeders for pneumatic transportation. SOLUTION: Each of an activated carbon storage tank 1, a special reaction assist storage tank 2, and a slaked lime storage tank 3 is formed with fixed- amount powder feed mechanisms 14a, 14b, (15a, 15b), (16a, 16b) for low pressure and high pressures to supply air of 35 kPa and 8 kPa from blowers 10, 11 through two systems of pneumatic transportation main piping 4, 5. Small- diameter pneumatic transportation small piping 6a, 6b, 6c, 7a, 7b, 7c for pneumatically incorporating powder delivered by the fixed-amount powder feed mechanisms for pneumatic transportation are provided at the respective fixed- amount powder feed mechanisms 14 to 16b, and the pneumatic transportation small piping with powder incorporated is connected to the pneumatic transportation main piping 4, 5 in parallel.
