Compared with the high - level torch, the enclosed type of ground torch has excellent environmental protection characteristics such as no smoke, no light pollution, low heat radiation, low noise and so on. Due to the above characteristics of the enclosed type ground torch, the arrangement of the edge of the production device can be arranged, and the spacing of the fire prevention is small, and the land investment can be saved.

Closed type ground flare consists of the burner on the ground, incandescent lamp, ignition device, furnace, heat radiation silencer, control device and other major facilities. According to the different characteristics of the exhaust gas, ground torch can also be used steam combustion, blast combustion and other measures.

After nearly ten years of development, processing capacity of single closed ground flare has reached 150t/h.
