  • Pulverized coal burner and pulverized coal boiler having it
    Patent number: 8950345
    Abstract: A pulverized coal burner and a pulverized coal boiler. The coal burner comprises a primary air cylinder (111) and a pulverized coal concentration device (112). The coal concentration device (112) makes the concentration of the coal flow gradually decrease from inside to outside along the radial direction, with respect to an axis (100) of the primary air cylinder (111). The coal burner further comprises a coal separating cylinder (113) and a coal guiding cylinder (114) located downstream of the device (112), the rear end of the cylinder (113) is connected with the front end of the coal guiding cylinder (114). The outlet of the cylinder (114) has a conical expansion portion (1141). The coal burner further comprises a divergent nozzle (115) connected with the rear end of the primary air cylinder (111) and whose cross-sectional area gradually increases along the flow direction of the coal flow.

  • Pulverized coal concentrator and pulverized coal burner including the concentrator
    Patent number: 8555795
    Abstract: A pulverized coal concentrator for a pulverized coal burner, the concentrator is fixedly arranged inside the pulverized coal burner and comprises a front part (102) and a rear part (101), wherein the front part (1020 is designed as a bowl-shaped structure, for guiding and concentrating an air-pulverized coal flow, and the rear part (101) is designed as a cylinder-shaped structure, for maintaining a proper extension of the dense phase zone of the air pulverized coal flow. Also a pulverization coal burner is provided comprising the pulverized coal concentrator, in particular an internal combustion-type pulverized coal burner. The pulverized coal concentrator increases the adaptability of burner to coal quality, air velocity and pulverized coal density.
