PURPOSE: A coal burner of pulverized coal combustion type without preheating is provided to send pulverized coal mixed with oxygen and hydrogen far by strong jetting power and to transmit the heating power to the wide portion of the combustion chamber. CONSTITUTION: A coal burner of pulverized coal combustion type without preheating is composed of hydrogen and air injection ports(9,10), an oxygen injection port(8), and a pulverized coal pipe(7a). The air injection port is connected to an air pipe(10a) positioned in the outermost rim. The hydrogen injection port is connected to a hydrogen pipe(9a) between the air pipe and an oxygen pipe(8a). The oxygen injection port is connected to the oxygen pipe. The outlet of the pulverized coal pipe is shaped like a horn-shaped protruded male spiral form. The pulverized coal pipe mixes hydrogen, oxygen, and combustion air by swirling the pulverized coal.
