Detailed Description

The utility model is further described below with reference to the figures and examples.

As shown in fig. 1.

The utility model provides a from smoke abatement type ground torch combustor, includes 3 ~ 8 the same arc torch gas distribution arms 4 (the cross section of torch gas distribution arm 4 is the wing section, see figure 2) that link to each other with torch gas main pipe 5, and torch gas distribution arm 4 is 360 evenly arranging around torch gas main pipe 5, as shown in figure 4. A plurality of groups of torch gas spray holes and corresponding fin 3 structures are uniformly arranged in the range of 90-130 degrees outside the torch gas distribution arm 4, each group of spray holes can be independently arranged, or each group of spray holes can comprise 1
