Abstract

The invention discloses a blade angle adjustable whirl pulverized coal burner, and solves the difficult problem that a universal four-channel whirl pulverized coal burner cannot adjust the swirling intensity of a swirler by changing the angle of a blade. The blade angle adjustable four-channel whirl pulverized coal burner is characterized in that (shown in figure 1) a blade angle adjustable swirler is arranged on the outer surface of a swirling air pipe (12) of a burning head (20), the swirling air pipe (12) forms a swirling air channel, and a swirling air pull rod adjusting device (33) is arranged at the tail end of the swirling air pipe (12) of an air supply device. The structure is reasonable, the operation is convenient, the swirler is arranged in the swirling air channel, the blade angle of the swirler is changed online through the adjusting device, so that the ideal burning state is achieved, and equipment support is provided for the production of high-quality calcined cement clinker.

Description

1. Technical field

[0001] The invention belongs to a thermal facility for calcining cement clinker, in particular to a four-channel swirl pulverized coal burner with adjustable swirl blade angles. 2. Background technology

[0002] The pulverized coal combustion equipment for calcining cement clinker usually adopts a four-channel swirling pulverized coal burner, and the adjustment and control means of the swirling airflow determine the performance of the burner. At present, for the general four-channel swirl pulverized coal burner, the adjustment and control of the swirling air flow is controlled by the regulating valve on the intake pipe (the intake pipe is called the swirl air duct because it is connected to the swirl air channel. The outlet of the swirl air channel is installed There are swirlers, which are also called wind fins, which are composed of blades with fixed angles, shaped like fan impellers, and have spiral grooves on the inner wall of the outlet pipe). If the...
