Problems solved by technology

At present, the low-nitrogen burners on the market are designed according to pipeline natural gas and standard three-pass boilers, while the structure of oilfield gas-fired heating furnaces is far from standard three-pass boilers and the gas sources used are complicated, and oilfield heating furnaces are usually operated in the field. The environment is very harsh, often facing strong winds, dust and other weather
The existing low-nitrogen burners have no experience in using oilfield heating furnaces, and there are no available products

Embodiment 1

[0032] see Figure 1 to Figure 5 , the embodiment of the present invention provides an ultra-low nitrogen burner for an oil field heating furnace, which includes a fan, and an outer cylinder 1 communicated with the air outlet of the fan, placed in the outer cylinder 1, and connected to the inner wall of the outer cylinder 1 The matching porous filler 3 is installed at the outer port of the outer cylinder 1, and the rotating vane orifice plate 2 whose normal direction is parallel to the direction of the centerline of the outer cylinder 1 is arranged at the outer port of the outer cylinder 1 and is located outside the rotating vane orifice plate 2 The firing pin 4 and the display control unit 7 electrically connected to the fan and the firing pin 4 respectively. When in use, a certain proportion of combustible gas and air premixed gas is blown into the outer cylinder by the air inlet of the fan through the fan. 1. After the premixed gas passes through the porous filler 3 and the...

Embodiment 2

[0042] see image 3, on the basis of Example 1, the others are the same as Example 1, the difference from Example 1 is that the porous filler 3 extends from the inner port of the outer cylinder 1 to the inner side of the rotary vane orifice plate 2, close to the rotary vane orifice plate 2 In this position, the filling length of the porous filler 3 is ensured, thereby ensuring the travel of the premixed gas in the porous filler 3, so that the premixed gas can be mixed uniformly.

Embodiment 3

[0044] see figure 2 and image 3 , on the basis of Example 2, the others are the same as Example 2, and the difference from Example 2 is that the porous filler 3 is provided with several layers of stainless steel honeycomb panels evenly stacked along the centerline direction of the outer cylinder 1, and each layer The diameter of the stainless steel honeycomb plate matches the inner diameter of the outer cylinder 1, which is convenient for materials and easy to make.

[0045] The holes of the adjacent two layers of stainless steel honeycomb panels are staggered and communicated, so that the premixed gas advances along the zigzag channel when passing through the porous filler 3, which increases the stroke of the premixed gas and further ensures the uniform mixing of the premixed gas.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to an ultra-low nitrogen burner for oil field heating furnaces. Background technique [0002] Low NOx burners or low nitrogen oxide burners refer to burners with low NOx emissions during fuel combustion. The use of low NOx burners can reduce nitrogen oxide emissions during combustion. The burner is an important equipment for industrial furnaces. It ensures the stable ignition of fuel and the complete combustion of fuel. Therefore, it is necessary to start with the burner to suppress the generation of NOx. There are many specifications and models of heating furnaces currently used in oil fields, and the liquid volume, temperature, working environment, and natural gas components and pressures used in heating furnaces are different for each well. At present, the low-nitrogen burners on the market are designed according to pipeline natural gas and standard three-pass boilers, while the...
