Abstract
A furnace-heating gas burner of the kind in which the burner head (1) is situated at one end of an inner pipe (2) which is surrounded by an outer protective pipe (3), and where a first part of the inner tube (2) that surrounds the burner head is provided, and wherein a separate inner pipe (8) is provided in the extension of the first pipe (2), which separate inner pipe (8) lies axially in line with the first pipe and commences at the open end of said first pipe (2). The invention is characterised in that at the end of the first pipe (2) which faces towards the separate pipe (8), the outlet of said first pipe has an inner diameter which is smaller than the diameter of the pipe in general.
Description
The present invention relates to a kind of gas burner.
The present invention is mainly used in industrial furnace.
The open No.9800473-2 of Swedish patent discloses a kind of method and combustion furnace that is used for cleaning the waste gas of for example discharging the oil burner from gas burner or from some other Combustion Source.
Usually utilize gas burner to come heat industrial furnaces.Common employed fuel is natural gas, but also can use other gas for example propane, butane and liquefied petroleum gas or bottled gas.
One of the efficient gas burner is exemplified as a kind of like this burner, the place, an end of pipe in wherein burner head is arranged on, and pipe is surrounded by the outer protection tube in its place, bottom sealing wherein.Hand down in interior pipe from the burning gases of combustion chamber and to deliver to the bottom of outer tube, they turn to reflux between outer tube and interior pipe and to enter in the exhaust steam passage that leads to external device (ED) there.Protection tube by convection current with 30% heat, by radiation with 70% heat transferred furnace space.
Similar burner also comprises an outer protection tube of managing and surround pipe in this in one, but not sealing of the bottom of this protection tube in this case.Protection tube is crooked, the structure that for example takes the shape of the letter U, and the free end of this protection tube is connected with exhaust steam passage.The interior pipe that cooperates with burner head is straight, and therefore is arranged in the straight portion of protection tube.
Preferably outer tube is remained under 1150 ℃-1200 ℃ temperature, so that improve the concentration of energy of this burner thus.This can by adopt high-temperature material for example the outer tube produced of carborundum (SiC) or APM realize.APM is the acronym of senior powder metallurgy (Advanced PowderMetallurgy), and related material comprises about 73%Fe, 22%Cr and 5%Al.This dusty material extrusion molding is a tubular form.
A problem is, when flame leaves burner head and beginning and contacts with interior pipe, is formed with such zone, wherein in temperature and the interior pipe of pipe plan the temperature of operation and compare and become too high easily.
The invention solves this problem.
Therefore the present invention relates to a kind of like this gas burner to the stove heating; the place, an end of pipe in wherein burner head 1 is located at; should in the outer protection tube of Guan Youyi around; be provided with in this gas burner round the first of the interior pipe of burner head; being provided with one in the extension of first pipe manages in separately; should become an axis ground to be provided with first pipe by interior separately pipe; and begin in its open end; this burner is characterised in that, the internal diameter of the outlet of first pipe less than this pipe at remainder towards the place, end of described first pipe of this single pipe.
The present invention will be described in more detail for its exemplary shown in the part reference in the accompanying drawings now, wherein:
Fig. 1 demonstrates the burner that constitutes according to the present invention.
Fig. 1 demonstrates the gas burner of the known type that is used to heat stove.This gas burner is such one type, the place, end of pipe 2 in wherein burner head 1 is arranged on, in this outer protection tube 3 of Guan Youyi around.The bottom 4 of protection tube 3 is sealed.Therefore, the bottom 4 from the waste gas of burner head will hand down and deliver to outer tube 3 in interior pipe 2 as refluxing between outer tube and interior pipe by equally turning to shown in the arrow, flows to the exhaust piping 5 that leads to external device (ED) then afterwards.
Fig. 1 demonstrates the first 2 around the interior pipe of burner head, and demonstrates the interior separately pipe 8 in the extension that is arranged on interior pipe 2.Pipe 8 and first is managed in line the earth's axis to setting in should be separately, and manages 2 open end first and begin.This first pipe 2 and interior separately pipe 8 are therefore in the axial direction each other in line.Pipe 8 begins in the open end of first pipe 2 separately.
The present invention is not limited to any specific gas burner or the burner of other type arbitrarily; but can be described the same with the burner of reference the above-mentioned type; but also has the interior pipe that is surrounded by the outer protection pipe; but wherein the bottom of protection tube is not sealed; but this protection tube is crooked, and the free end of described pipe is connected with exhaust piping.
Fuel gas is delivered into inlet 6, and combustion air is delivered into inlet 7.
According to the present invention, the interior diameter of the outlet of first pipe is less than the diameter of this pipe at the remainder of locating towards that end of independent pipe.
In the embodiment of Fig. 1, first pipe 2 narrows down at its lower end.Gradually thin part 9 makes the speed of gas increase towards mouth 10.And this means that the flame 11 that sends from mouth will be than longer when adopting columniform fully first pipe usually.And longer flame mean promptly will be than much bigger in the situation of ordinary burner by the surface area of flame contact by the inner surface area of the direct-fired single pipe of this flame.
Find that surprisingly although although the heat that flame sends is with as many and from two sides internal pipe 8 heats in the situation of conventional burners, the problems referred to above have been eliminated in this expansion of flame.
According to the preferred embodiments of the invention, the less internal diameter of mouth 10 is 10%-50% of internal diameter of the remainder of this pipe.
According to another preferred embodiment of the present invention, the mouth 10 of first pipe 2 is located substantially on proximal openings 12 places of single pipe 8.
Though some embodiment is described, should be understood that gradually thin part can have taper or some other shapes.
Therefore, it being understood that the present invention should not be regarded as being limited to above-mentioned illustrational embodiment, but can make a change within the scope of the appended claims.
Claims (3)
1. gas burner to stove heating; wherein burner head (1) is positioned at the place, an end of pipe (2); should in Guan Youyi outer protection pipe (3) around; be provided with in this gas burner round the first of the interior pipe (2) of burner head; pipe (8) in the extension of first pipe (2), being provided with separately; be somebody's turn to do separately interior pipe (8) becomes an axis ground to be provided with and begins in described first open end of managing (2) with first pipe; it is characterized in that; at the end place towards first pipe (2) of single pipe (8), the internal diameter of the outlet of described first pipe is usually less than the diameter of this pipe.
2. burner as claimed in claim 1 is characterized in that, described less internal diameter is generally the 10%-50% of the internal diameter of first pipe (2).
