A high velocity gas burner comprised of a gas nozzle (1) imparting said high velocity to the emerging gas flame from nozzle; a flame-stabilizing disc (2) provided preferably near exit to stabilize said high velocity flame. A gas-connecting nozzle (3) supplying the fuel gas at a pressure range of 200-250 mmWC and receiving it from inlet pipe (4). A combustion air nozzle (5), acting as the burner block and connected to air connecting nozzle (6) to supply the requisite amount of airflow from air blower at a pressure of 200-400 mmWC through combustion air annular pipe and combustion air inlet pipe, generating high velocity flames with firing capacity ranging from 100-500 Nm3/hr. The burner block and the gas nozzle and the flame-stabilizing disc, is made of AISI: St 31O grade steel for longer life. Control valves are provided to control air-fuel ratio in measured amounts displayed on a panel, maintaining excess air of about 10% for complete combustion. The long and stable flame suitable for higher uniform ladle preheating temperature up to about 1200°C. No. of Pages : 14 No. of Claims : 10
