A closed ground flare system

Abstract

The invention discloses a closed ground torch system, comprising a torch body and a burner arranged in the torch body. The direction is toward the center of the torch body; one side of the burner is provided with an ignition permanent light; an air inlet is provided on the torch body at the position of the burner and the ignition permanent light, and the ground torch system disclosed in the present invention has the advantages of low combustion flame height, low burning flame With the advantages of high efficiency and low investment cost, it is suitable for the safe, efficient and environmentally friendly combustion of large-flow flare gas.

Description

technical field [0001] The invention relates to a ground torch, in particular to a closed ground torch system. Background technique [0002] The torch system is an important safety facility for refining and chemical enterprises, and its safe and stable operation is of vital significance to the safety production of enterprises. The main function of the flare system is to burn and treat the hydrocarbon flare gas emitted by each device during start-up and shutdown and under abnormal working conditions. Torches can be divided into overhead torches and ground torches according to whether the burner is far from the ground, and ground torches are further divided into closed ground torches and open ground torches. [0003] The existing closed ground torch has a cylindrical structure, which is composed of a combustion chamber body, a combustion chamber pillar, a burner, and a windproof and sound-absorbing wall of the combustion chamber. In order to achieve staged combustion, the gr...

AI Technical Summary

Problems solved by technology

[0006] (1) When dealing with large flow of flare gas, it is necessary to increase the number of ground flare burners, and the concentrated combustion of multiple burners leads to a higher flame height

In order to ensure that the flame is inside the ground flare barrel and reduce the heat radiation of the ground flare to the outside world, it is necessary to increase the height of the barrel, which greatly increases the investment cost. At the same time, the tens of meters high barrel structure brings greater safety risks

[0007] (2) With the increase of the closed ground torch processing capacity, the number of burners increases, and the diameter of the cylinder becomes larger, resulting in insufficient air distribution of the burner in the center of the cylinder, low combustion efficiency of the torch burner, and increased unburned gas Emissions
