Description
Technical field
The present invention relates to gas burners, are in particular that a kind of bar type staged burners are mixed with gas-air supply
Structure.
Background technique
When designing gas steam engine using bar type burner and be premixed gas from bar type burner fire hole upwards
Outflow burning, air-flow on heat exchangers under end-stopping plate inclined-plane resistance and guide functions, make combustion flame and flue gas change direction, court
When being flowed to bar type burner down either side, it is necessary to which premixed gas must possess enough pressure when flowing out from burner fire hole
And kinetic energy, powerful gas kinetic energy change the flow direction of combustion flame and flue gas to flowing downward, so by flowing up
Can avoid combustion tail gas to collect and stop in side space on the burner, allow combustion tail gas take advantage of a situation discharge downwards, for combustion
The premixed gas of the subsequent outflow of burner continues efficient burning and creates necessary condition；However this type combustion heat-exchange structure is carrying out
Small fire burning in cannot being carried out by the way of reducing fire hole heat flow when the big minor adjustment of heat flow, because fire hole heat flow reduces
The premixed gas pressure and flow velocity that flow out from fire hole certainly will be made to reduce, gas flow rate reduction will make combustion flame and flue gas lose foot
Enough kinetic energy is along heat exchanger top plate and side plate to burner flowing underneath, and will lead to combustion tail gas, square combustion chamber is empty on the burner
Between be detained, row mixes again with the subsequent outflow premixed gas of burner for the tail gas of delay, and the carbon dioxide in tail gas will certainly be to pre-
Mixed gas burning has an impact, or even causes the bad result of combustion reaction termination, fray-out of flame.Because of the invention bar type burner
Sectional combustion is carried out, is independently supplied gas-air mixed gas for each section of burner, mating adaptable combustion gas and air supply
To pipeline and switch, controlled by regulating switch each section of burner can work independently, by allow one section of burner operation,
The work of two stage combustion device or whole burner operation come realize heat flow it is small in adjust use greatly, and then do not changing burning fire
In the case where hole premixed gas outflow pressure and flow velocity, realize burner heat flow it is small, in, the adjusting in big section conversion, so
It designs a kind of bar type staged burners and gas-air supplies mixed structure.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of bar type staged burners to mix knot with gas-air supply
Structure, can provide it is a kind of in the case where not reducing fire hole gas flow rate, adjust burner heat flow size, burning and combustion gas
Air supplies mixed structure.
In order to solve the above technical problems, being in particular a kind of bar type sectional combustion the present invention relates to gas burner
Device and gas-air supply mixed structure, including fuel gas conduit, air hose, the first valve, the second valve, third valve, third are pre-
Gas mixing pipe, the second pre- gas mixing pipe, the first pre- gas mixing pipe, combustion chamber and top plate can provide a kind of convenient for adjusting burner combustion
The supply mixed structure of size.
It is divided into three Room of one Room of burner, two Room of burner and burner in the combustion chamber；The third premixes gas
Pipe, the second pre- gas mixing pipe and the first pre- gas mixing pipe are connected with air hose, the pre- gas mixing pipe of the third, the second pre- gas mixing pipe and
First pre- gas mixing pipe is connected by third valve, the second valve and the first valve with fuel gas conduit；The pre- gas mixing pipe of the third
Be connected with one Room of burner, the pre- gas mixing pipe of described second is connected with two Room of burner, the pre- gas mixing pipe of described first with
Three Room of burner is connected.
As advanced optimizing for the technical program, combustion described in a kind of novel burner supply mixed structure of the present invention
One Room of burner, the mutual exclusion seal in two Room of burner and three Room of burner.
A kind of bar type staged burners of the present invention have the beneficial effect that with gas-air supply mixed structure
Can provide it is a kind of in the case where not reducing fire hole gas flow rate, adjust burner heat flow size, burning and combustion
Gas air supplies mixed structure.
Detailed description of the invention

Specific embodiment
Specific embodiment:
Illustrate present embodiment below with reference to Fig. 1, Fig. 2 and Fig. 3, the present invention relates to gas burners, are in particular a kind of
Bar type staged burners and gas-air supply mixed structure, including fuel gas conduit 1, air hose 2, the first valve 3, the second valve 4,
The pre- gas mixing pipe 6 of third valve 5, third, the second pre- gas mixing pipe 7, the first pre- gas mixing pipe 8, combustion chamber 9 and top plate 10, can provide
It is a kind of in the case where not reducing fire hole gas flow rate, adjust burner heat flow size, burning and gas-air supply it is mixed
Close structure.
It is divided into three Room 9-3 of one Room 9-1 of burner, two Room 9-2 of burner and burner in the combustion chamber 9；Described
The pre- gas mixing pipe 6 of third, the second pre- gas mixing pipe 7 and the first pre- gas mixing pipe 8 are connected with air hose 2, the pre- gas mixing pipe of the third
6, the second pre- gas mixing pipe 7 and the first pre- gas mixing pipe 8 are connected by third valve 5, the second valve 4 and the first valve 3 with fuel gas conduit 1
It connects；The pre- gas mixing pipe 6 of the third is connected with one Room 9-1 of burner, the pre- gas mixing pipe 7 and two Room 9- of burner of described second
2 are connected, and the pre- gas mixing pipe 8 of described first is connected with three Room 9-3 of burner.
One Room 9-1 of burner, the two Room 9-2 of burner and the three mutual exclusion seal of Room 9-3 of burner.
To solve bar type burner changing the premixed gas pressure flowed out from fire hole and adjusting hot-fluid by way of flow velocity
When amount, gas kinetic energy reduction make combustion tail gas combustion chamber be detained, cause combustion reaction that can not normally complete the problem of, provide one
Burner is divided into several sections, makes it that can independently do work by kind, is the mating independent premixed gas distributor chamber of each section of burner, combustion
Plate and fire hole, mating independent premixed gas conveyance conduit, airflow pipe, fuel gas transportation pipeline are burnt, and possesses independence
Burnt gas valve；Be each section of mating connection of burner airflow pipe in long logical state, after opening burnt gas valve, combustion gas
It flows into premixed gas conveyance conduit by fuel gas transportation pipeline to be mixed with the air that airflow pipe flows into, mixed gas stream
Enter corresponding burner premixed gas distributor chamber, by burner plate fire hole flow out burn, because every section of burner can independently by
Control acting can realize that one section of burner does work, two stage combustion device does work or all fires by manipulating corresponding burnt gas valve
Burner acting, every section of burner all do work under its specified heat flow tune part at full capacity, and there is no need to reduce premixed gas outflow
The large, medium and small adjusting conversion of heat flow can be realized in pressure and flow velocity, can be the smooth discharge of tail gas and continuing surely for combustion reaction
Surely creation necessary condition is carried out.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, the art
The variations, modifications, additions or substitutions that those of ordinary skill is made within the essential scope of the present invention also belong to guarantor of the invention
Protect range.
