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.
