In order to solve the problem of that the boiler burns inferior coal but cannot guarantee the combustion stability, the rich-lean burner divides primary wind pulverized coal airflow into two stocks of airflows containing different amounts of pulverized coal and sends the airflows into coal-fired furnace for improving the ignition characteristics. By the numerical simulation of the pulverized coal flow characteristics in an elbow bias-oriented rich-lean burner, regarding the “concentration ratio” and “speed difference” as the standard of evaluating the separation characteristic of the burner, considering the influence of the partition plate length, bias current stopper height and primary wind velocity to the separation effect of pulverized coal so as to provide technical assistances for the elbow bias-oriented rich-lean burner’s practical application and improvement.
