Abstract

[0001] The present disclosure relates to a center air jet burner for burning low quality fuel including an annular pipe having a fuel inlet and a fuel outlet. A core pipe that includes a first opening and an opposite second opening that defines an inner zone, the core pipe extends within the annular pipe defining a first annular zone. A burner elbow is configured to supply a fuel airflow mixture including pulverized coal and primary air to the fuel inlet and the first opening. The first opening of the core pipe is eccentrically aligned relative to the fuel inlet of the annular pipe such that the fuel airflow mixture passing through the burner elbow is divided into an outer fuel rich stream having an increased amount of pulverized coal within the first annular zone and an inner fuel-lean stream having an increased amount of primary air within the inner zone.
