| titleOfInvention | Coal distribution device of circulating fluidized bed boiler |
| abstract | The utility model discloses a coal distribution device of a circulating fluidized bed boiler. The coal distribution device comprises a coal dropping straight pipe, a first coal dropping oblique pipe, a second coal dropping oblique pipe, a sealing air pipe and a coal distribution opening, wherein the lower end of the coal dropping straight pipe is communicated with the upper end of the first coal dropping oblique pipe and the lower end of the first coal dropping oblique pipe is communicated with the second coal dropping oblique pipe. The coal distribution device is characterized in that the second coal dropping oblique pipe is of an integrally formed structure and is composed of a shrinkage section, a throat section and an expansion section, the central axes of which are overlapped with each other; the shrinkage section is used for strengthening the sealing pneumatic pressure; the throat section is used for maintaining the sealing air pressure; the expansion section is used for strengthening the sealing air pressure; the sealing air pipe is communicated with the shrinkage section; the inlet of the sealing air pipe is arranged outside the shrinkage section and the outlet of the sealing air pipe is arranged inside the shrinkage section; the expansion section is communicated with the coal distribution opening. By improving the structure of the coal dropping pipes, the loss of the sealing air pressure is effectively compensated and the positive pressure of smoke from a hearth is counteracted by the sealing air pressure, so that the smoke is prevented from jumping backwards and the effect of environment friendliness is improved. |
