Description
Technical field
The present invention relates to a kind of injection type burner, more particularly to a kind of Stress control of injection type burner is consolidated
Definite value adjusts system.
Background technology
In petrochemical equipment, that is discharged in the timely process for producing device of Venting and Flare Stack System energy is unnecessary, harmful, unbalanced
Waste gas, and the unqualified gas produced when test run, driving and parking can be processed, and the instantaneous a large amount of gases released during accident, it is ensured that
Device is normal, safe operation.Torch burning will keep the stability of flame, if there is the problem of fray-out of flame, will make largely to have
Poison, the gas for having burn into inflammable and explosive are excessive, diffusion, will not only cause casualties, and pollute environment, and serious meeting causes
Blast, fire.And, if fuel combustion incomplete combustion, inefficient combustion, it will produce a large amount of noxious emissions, such as
Carbon monoxide, nitrogen oxides etc..
Venting and Flare Stack System typically uses injection type burner, and it is fired using some venturi burners to combustion gas
Burn.Opening or closing for burner air-supplying valve is the pressure according to fuel come fixed.Control valve controls the maximum of the circulation valve
Fuel quantity, more than the fuel quantity, then the burner opened at present cannot be effectively treated to the amount for exceeding, and burn insufficient,
Produce a large amount of noxious emissions.Therefore need to open more control valves, allow more burners to participate in burning.Different fuel
Composition or impurities are different, and the Stress control fixed value of valve is also different.If Stress control fixed value and fuel composition
Mismatch, then torch operating mode is unstable and there may be a large amount of noxious emissions.
The content of the invention
In view of this, the present invention proposes a kind of Stress control based on fuel composition for solving at least one above mentioned problem
Fixed value adjusts system.
A kind of Stress control fixed value adjustment system based on fuel composition of present invention offer, including fuel feed line,
The some control valves and some venturi burners being connected with the fuel feed line, the control valve are arranged on the fuel
To control the valve opening of the fuel feed line on feeding pipe, the control valve has a Stress control fixed value, its
It is characterised by, the Stress control fixed value adjustment system includes a controller, the controller is connected with the control valve, uses
To control the Stress control fixed value of valve described in the composition adjust automatically according to the fuel in the fuel feed line.
In one embodiment, also including a fuel composition detector, the fuel composition detector is supplied with the fuel
Pipeline is connected to detect the composition of the fuel in the fuel feed line, and the fuel composition detector is connected with the control
The controller is sent to by the result of the detection.
In sum, system is adjusted the invention provides a kind of Stress control fixed value based on fuel composition, using control
Device processed controls the Stress control fixed value of valve according to fuel composition adjust automatically, makes Stress control fixed value and different fuel composition
Adapt to, improve the combustion stability of flare system.
Brief description of the drawings
Fig. 1 is the rough schematic view of the combustion system of injection burner.
Fig. 2 is the schematic diagram that Stress control fixed value adjusts system.
Specific embodiment
Before describing the embodiments in more detail, it should be understood that the invention is not restricted to institute hereafter or in accompanying drawing in the application
The detailed construction or arrangement of elements of description.The present invention can be the embodiment that other manner is realized.Furthermore, it is to be understood that this paper institutes
The wording and term for using are solely for describing purposes, should not the explanation of being construed as limiting property.It is used herein " including ", "comprising",
The similar wording such as " having " is meant comprising items listed thereafter, its equivalent and other additional things.Particularly, description is worked as
When " certain element ", the quantity that the present invention does not limit the element is one, it is also possible to including multiple.
If Fig. 1 is the rough schematic view of the combustion system of injection burner, including fuel feed line 10 and fuel are supplied
To the control valve 20 and venturi burner 30 of the connection of pipeline 10.Fuel supply conduit 10 is by the combustion from fuels sources such as oil well
Gas is delivered to venturi burner 30 and is burnt.The quantity of venturi burner 30 can be one or more, and quantity is not done
Limitation.Control valve 20 is arranged on fuel feed line 10 to control the valve opening of the fuel feed line.Fuel is supplied
Pipeline 10 can have multiple branch roads, each branch road to control valve 20 as setting one and be connected with one or more venturi
Burner 30.Fig. 1 only symbolically draws two branch roads.
Control valve 20 has a Stress control fixed value.For the venturi burner of design typification, it can be processed
Combustion gas total amount have a maximum.Therefore, if the pressure of the combustion gas in pipeline exceedes the Stress control fixed value, then it represents that
Gas quantity in pipeline has exceeded the maximum throughput of connected venturi burner, now needs to open the text of more multiple branch circuit
Burner burns to combustion gas in mound.
For different combustion gas, because the impurity that it contains is different, the maximum throughput of venturi burner is also different.
In general, the Stress control fixed value of control valve 20 is arranged on 0.8Mpa.Torch gas component includes different hydrocarbons,
Such as H2、H2S、CO2、N2Deng, the relative percentage of every kind of gas also in lasting change, so as to determine the mean molecule of torch
Amount and density are also continually changing, therefore flow pressure changes.Therefore, Stress control fixed value adjustment system of the invention will
For the Stress control fixed value of different combustion gas composition adjustment control valves 20.
Such as Fig. 2, in the present embodiment, the Stress control fixed value adjustment system includes that a controller 40 and fuel composition are examined
Survey device 50.Controller 40 is connected with control valve 20, to the composition adjust automatically according to the fuel in the fuel feed line
The Stress control fixed value of the control valve 20.Fuel composition detector 50 is connected to detect the combustion with fuel feed line 10
The composition of the fuel in material feeding pipe 10, the fuel composition detector 50 is connected with by the detection with the control 40
Result is sent to the controller 40.
In addition, in some cases, processed combustion gas in oil well there, analyzed fuel into
Part and type, now avoid the need for the detection of fuel composition detector 50, it is only necessary to by fuel composition and type input controller
40.
In the above-described embodiments, the Stress control fixed value of valve is controlled according to fuel composition adjust automatically using controller,
Stress control fixed value is adapted to different fuel composition, improve the combustion stability and the feature of environmental protection of flare system.
Concepts described herein may be embodied to other forms in the case of without departing from its spirit and characteristic.It is disclosed
Specific embodiment should be considered as exemplary rather than restricted.Therefore, the scope of the present invention be by appended claim,
It is determined rather than these descriptions before basis.Any change in the letter and equivalency range of claim is all
The scope of these claims should be belonged to.
