Abstract: This application describes examples of a data processing method and apparatus. In one example, the method includes: If a target buffer that is corresponding to a target priority and that is on a network device reaches a first threshold, the network device sends a pause message to an upstream device, so that the upstream device stops sending a first data packet corresponding to the target priority. If a duration in which the network device stops buffering a second data packet is greater than a preset duration, and the target buffer falls back below a second threshold, the network device sends a sending resumption message to the upstream device, so that the upstream device sends a third data packet corresponding to the target priority.

Abstract: A two-channel burner includes a pulverized coal supply mechanism, a transition channel, an inner secondary air guide tube, an outer secondary air guide tube, a combustion stabilizing chamber, and a flow smoothing chamber. The outer secondary air guide tube, the combustion stabilizing chamber, and the flow smoothing chamber are sequentially connected to form a burner body. The pulverized coal supply mechanism passes through an interior of the burner body. The transition channel is fitted over the pulverized coal supply mechanism. The inner secondary air guide tube is disposed between the transition channel and the outer secondary air guide tube and forms an inner secondary air passage together with the transition channel, and forms an outer secondary air passage together with the outer secondary air guide tube. An outlet end of the inner secondary air guide tube is formed to have a flared opening.
