Description
Technical field
The present invention relates to a kind of injection type burner, particularly relate to a kind of Stress control fixed value adjustment System of injection type burner.
Background technology
In petrochemical equipment, unnecessary, harmful, the unbalanced waste gas discharged in the timely process for producing device of Venting and Flare Stack System energy, and the defective gas produced when can process test run, start-stop car, and a large amount of gases of instantaneous releasing during accident, assurance device is normal, safe operation.Torch burning will keep the stability of flame, if there is the problem of fray-out of flame, by making, gas that is poisonous, that have burn into inflammable and explosive is in a large number excessive, diffusion, and not only will cause casualties, contaminated environment, serious meeting causes blast, fire.Such as, and if fuel combustion incomplete combustion, inefficient burning, will produce a large amount of noxious emission, carbon monoxide, nitrogen oxide etc.
Venting and Flare Stack System generally adopts injection type burner, and it uses some venturi burners to burn to combustion gas.It is fixed that the opening or closing of burner air-supplying valve is that the pressure of based on fuel comes.Control valve controls the greatest amount of fuel of this valve of circulation, exceedes this fuel quantity, then the burner opened at present effectively cannot process the amount exceeded, and burns insufficient, produces a large amount of noxious emission.Therefore need to open more control valve, allow more burner participate in burning.Composition or the impurities of different fuel are different, and the Stress control fixed value of valve is also different.If Stress control fixed value is not mated with fuel composition, then torch operating mode is unstable also may produce a large amount of noxious emission.
Summary of the invention
In view of this, the present invention proposes a kind of Stress control fixed value adjustment System based on fuel composition solving at least one the problems referred to above.
The invention provides a kind of Stress control fixed value adjustment System based on fuel composition, comprise fuel feed line, the some control valves be connected with described fuel feed line and some venturi burners, described control valve is arranged on described fuel feed line to control the valve opening of described fuel feed line, described control valve has a Stress control fixed value, it is characterized in that, described Stress control fixed value adjustment System comprises a controller, described controller is connected with described control valve, in order to automatically to adjust the Stress control fixed value of described control valve according to the composition of the fuel in described fuel feed line.
In one embodiment, also comprise a fuel composition detector, described fuel composition detector is connected the composition of the fuel detected in described fuel feed line with described fuel feed line, described fuel composition detector and described control connection are to be sent to described controller by the result of described detection.
In sum, the invention provides a kind of Stress control fixed value adjustment System based on fuel composition, utilize controller based on fuel composition automatically to adjust the Stress control fixed value of control valve, Stress control fixed value and different fuel composition are adapted to, improve the combustion stability of flare system.
Accompanying drawing explanation
Fig. 1 is the rough schematic view of the combustion system of injection burner.
Fig. 2 is the schematic diagram of Stress control fixed value adjustment System.
Detailed description of the invention
Before describing the embodiments in more detail, it should be understood that and the invention is not restricted to detailed construction in the application hereafter or described in accompanying drawing or arrangement of elements.The present invention can be the embodiment that alternate manner realizes.And, should be appreciated that wording used herein and term are only used as to describe purposes, should being construed as limiting property not explain.Similar wording meant and comprised item listed thereafter, its equivalent and other additional things " comprising " used herein, " comprising ", " having " etc.Particularly, when describing " certain element ", the quantity that the present invention does not limit this element is one, also can comprise multiple.
Be the rough schematic view of the combustion system of injection burner as Fig. 1, comprise fuel feed line 10, the control valve 20 be connected with fuel feed line 10 and venturi burner 30.Fuel gas transmission from fuels sources such as oil well burns to venturi burner 30 by fuel supply conduit 10.The quantity of venturi burner 30 can be one or more, and quantity does not limit.Control valve 20 is arranged on fuel feed line 10 to control the valve opening of described fuel feed line.Fuel feed line 10 can have multiple branch road, and each branch road arranges such control valve 20 and is connected with one or more venturi burner 30.Fig. 1 only schematically draws two branch roads.
Control valve 20 has a Stress control fixed value.For the venturi burner of design typification, its treatable combustion gas total amount has a maximum.Therefore, if the pressure of the combustion gas in pipeline exceedes this Stress control fixed value, then represent that the gas quantity in pipeline has exceeded the maximum throughput of connected venturi burner, now needs the venturi burner opening more multiple branch circuit to burn to combustion gas.
For different combustion gas, the impurity contained due to it is different, and the maximum throughput of venturi burner is also different.Generally speaking, the Stress control fixed value of control valve 20 is arranged on 0.8Mpa.Torch gas component comprises different hydrocarbons, such as H
2, H
2s, CO
2, N
2deng, the relative percentage of often kind of gas also in lasting change, thus determine the mean molecule quantity of torch and density also constantly changes, therefore flow pressure changes.Therefore, Stress control fixed value adjustment System of the present invention will for the Stress control fixed value of different combustion gas compositions adjustment control valve 20.
As Fig. 2, in the present embodiment, described Stress control fixed value adjustment System comprises a controller 40 and fuel composition detector 50.Controller 40 is connected with control valve 20, in order to automatically to adjust the Stress control fixed value of described control valve 20 according to the composition of the fuel in described fuel feed line.Fuel composition detector 50 is connected the composition of the fuel detected in described fuel feed line 10 with fuel feed line 10, with described control 40, described fuel composition detector 50 is connected that the result of described detection is sent to described controller 40.
In addition, in some cases, combustion gas is processed in oil well there, analyzed composition and the type of fuel, now just do not need the detection of fuel composition detector 50, only need fuel composition and type input control device 40.
In the above-described embodiments, utilize controller based on fuel composition automatically to adjust the Stress control fixed value of control valve, Stress control fixed value and different fuel composition are adapted to, improve combustion stability and the feature of environmental protection of flare system.
Concept described herein may be embodied to other form when not departing from its spirit and characteristic.Disclosed specific embodiment should be regarded as exemplary instead of restrictive.Therefore, scope of the present invention is by appended claim, instead of determines according to these descriptions before.Any change in the letter and equivalency range of claim all should belong to the scope of these claims.
