| titleOfInvention | A diffused-tube multi-chamber split-type fluidized-bed furnace for the production of reduced iron or iron carbide |
| abstract | A diffused-tube multi-chamber split fluidized-bed furnace for producing reduced iron or iron carbide is provided. SOLUTION: A first fluidized bed furnace 1 and a second fluidized bed furnace 2 are divided into multiple chambers by a partition plate 5 arranged in a vertical direction. A gas pipe 11 extending from the first heating furnace 3 for heating the reaction gas to the lower part of the first fluidized bed furnace is installed, and the pipe is branched from the gas pipe 11 into a grid for each divided chamber via a collecting pipe 12. A number of gas blowing nozzles are provided on the pipe. Similarly, a gas pipe 11a extending from the second heating furnace 4 for heating the reaction gas to the lower part of the second fluidized bed furnace is installed, and the pipe is branched from the gas pipe 11a into a grid shape for each divided chamber via the collecting pipe 12a. A large number of gas blowing nozzles are provided in this grid-like pipe. Then, in the first fluidized-bed furnace 1 or the second fluidized-bed furnace 2, the fluidized bed heights (H 1 ) or (H 2 ) of all the divided chambers are substantially the same, respectively, from the divided chambers on the raw material input side. The height of the gas blowing nozzle in each of the divided chambers is reduced stepwise over the divided chambers on the product discharge side in accordance with the layer height difference caused by the raw material transfer force between the divided chambers. |
