Abstract: Flares can burn out waste gas from producing process. The ground flare uses new type burners, burning tower and a separating burning control system to get a good method to deal with waste gas. It has advantages of wide scale in dealing capability, burning efficiently, no smoke, no light pollution, no heat radiation and low noise. So, it is an environmental friendly process to deal with the gases. There were some problems in running of the ground flare, such as the burners unable to light each other, the gas pressure of water seal tank of torch being over its safe pressure, the blocking of torch gas pipes and water seal tank pipes, and the pilot burner unable to move properly. By the development of equipment and adjusting of running date, these problems were solved. The possibility of reducing the number of pilot burners to save nature gas was raised and the methods of promoting the reliability of the separating burning control system discussed.
