摘要： This invention is about a coal feeding system (1) which feeds pulverized coal and oxygen separately and vertically through concentric pipes directly to the upper level of the reactor (R) at entrained flow gasification systems. The system (1) consists a top intake (2), a side intake (3), an air supply chamber (4), an oxygen port (5), an ultrasonic sensor port (6), an inner concentric pipe (7), and an outer concentric pipe (8). The system (1) also operates with a coal bunker (K), a screw feeder (B) for adjusting the coal mass flow rate from the coal bunker (K) through the coal feeding system (1) to the reactor (R), and a reactor (R) where the coal are sprayed from the coal feeding system (1) and gasified at high temperatures.
