High-efficiency ground torch and stable combustion measure thereof

Abstract

The invention discloses a ground torch and a stable combustion method of the high-efficiency ground torch. The high-efficiency ground torch structurally comprises a barrel, fire observing holes, a burner, a columnar base and a control part, wherein the barrel is installed on the columnar base, a plurality of fire observing holes are annularly distributed in the side wall of the barrel, and the burner is divided into a plurality of levels and is arranged in the barrel. According to the high-efficiency ground torch, the problems of low burn-off rate, unstable graded burning switch, high manufacturing cost of the burner and the like existing in a conventional ground torch can be solved, the burning effect of torch gas is improved greatly, the burn-off rate is increased, the unsafe factors in the graded burning switch process are eliminated, and the high-efficiency ground torch has the advantages that the investment is lowered and the like.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a ground torch and a method for stabilizing its combustion. Background technique [0002] The currently disclosed ground torch technologies are mainly closed ground torches and open ground torches. Multiple burners are used in these two technologies. According to the user's usage, the diameter of the nozzle hole on the burner is generally 5 ~8 mm. Secondly, these burners are arranged in a plane, and use the form of staged combustion, that is, after the pressure detection element detects that the pressure of the flare gas rises to the set value, the interlock opens the secondary or tertiary burner for combustion . [0003] The current technology has the following problems in use: [0004] ①The nozzle hole of the burner is large, which is not easy to mix with air, which prolongs the burnout time, resulting in incomplete combustion and low combustion efficiency after...

AI Technical Summary

Problems solved by technology

[0004] ①The nozzle hole of the burner is large, which is not easy to mix with air, which prolongs the burnout time, resulting in incomplete combustion and low combustion efficiency after the smoke is discharged from the cylinder;

If at this time the first-stage torch has a large leak due to burnout, etc., the pressure of the torch gas cannot be increased to the set value, and the combustion task that should have been completed by the two-stage burner still has the first-stage burner to burn. The result is bound to cause a serious accident;

[0006] ③The condition for the torch control system to open the other stage burner is that the pressure of the torch gas rises to the set value. For example, the control system automatically opens the secondary burner when the pressure of the torch gas reaches the set value of the secondary burner. The condition for achieving ignition is that the gas ejected from the nozzle hole diffuses to the open flame of the first-stage burner, and at this time the pressure of the first-stage burner is higher, and the flame moves upward, so the diffusion height of the gas ejected by the second-stage burner must increase. The amount of unburned gas increases, and deflagration will occur when it comes into contact with an open flame, which will affect the stability and safety of the flare system;

[0007] ④The burner has many parts, complex structure and high cost
