Multi-channel Pulverized Coal Burner

  

 Introduction of Multi-channel pulverized coal burner:

   Multi-channel pulverized coal burner technology is top of the new pulverized coal burner, it developed a new high efficiency pulverized coal burner. It can be instead of the traditional pulverized coal burner, such as conventional DC burners, ship burners etc.
   Multi-channel pulverized coal burner has a simple mechanism, smoothly and fully burning, flame lively and strong, good rigidity, not to hurt the kiln skin, good maintainability, post-maintenance cost is low, the key components apply the ceramic components which is resistant to high temperatures. Operation is stable and reliable and the investment is small.
   The working Principle of Multi-channel pulverized coal burner:

   Gas from the gas pipeline on the basis of certain diffusion angle swirl outward emitted, the outside neighbor swirl wind pass a very high momentum and moment of momentum, spiral forward and continue to radial diffusion at a high-speed, meeting the high-speed axial wind. The insertion of the axial flow wind can enhance the mixture of combustion gas and air, and may adjust the degree of divergence of the flame and adjust the flame length, thickness, to achieve the desired flame shape. The center wind plays the role of supplemental oxygen, make the fuel burn more fully, and can stabilize the airflow.
