Make method.
Background technology
The scale development of China's regenerative resource installation in recent years is rapid, and more and more unstable new energy access power grid
Afterwards, huge challenge is proposed to the safe and stable operation of power grid.Also there is serious " abandon wind and abandon light " phenomenon in some areas.
National policy adjusts, mandatory requirement regenerative resource online, this imply that role of the thermoelectricity in energy resource supply will
From basic, routinely the energy changes to peak regulation, stand-by power source, i.e., thermal power plant will be with the ability of flexibility peak regulation.Boiler is low
Most direct means of the load combustion technology as thermal power plant's flexibility peak regulation, wherein burner underrun technology are most to close
The technology of key.
Invention content
In order to overcome the disadvantages of the above prior art, the purpose of the present invention is to provide a kind of burners of adjustable load
And working method, it is simple in structure, can significantly adjust burner load, it is especially adapted for use in opposed firing boiler-burner
And gas burner.
To achieve the goals above, the technical solution adopted by the present invention is：
A kind of burner of adjustable load, including the center wind duct 1 of from-inner-to-outer setting, First air channel 2 and two
Secondary wind channel 4, First air channel 2 are connected to coal dust channel 3, convey fuel for combustion apparatus, center wind duct 1 and Secondary Air are logical
Road 4 is that combustion apparatus conveys air, which is characterized in that the tube wall of center wind duct 1 is by the Outer Tube wall 1 that is axially movable
It is nested connection composition with fixed inner duct wall 1, the outer tube wall of secondary air channel 4 is by the Outer Tube wall 28 that is axially movable
It is nested with fixed inner duct wall 26 and connects composition, the inner tubal wall of secondary air channel 4 and the outer tube wall in First air channel 2 are
The head of fixed duct wall 9, the Outer Tube wall 28, duct wall 9 and Outer Tube wall 1 is in shrink mouth shape.
The Outer Tube wall 28 does axial displacement by controlling executing agency 27, and the Outer Tube wall 1 passes through control
Axial displacement is done by executing agency 5, so that 4 cross-sectional area of First air channel 2 and secondary air channel changes, and then adjusts
First air and secondary wind wind speed.
It is both provided with spinning disk 12 in the First air channel 2 and secondary air channel 4.
The working method of the burner of load is adjusted in the present invention, it is characterised in that：
When burner needs to run under high loads, control executing agency 7 and control executing agency 5 control outer tube respectively
Road wall 28 increases First air channel 2 and two to cephalad direction axial movement and the rearwardly direction axial displacement of Outer Tube wall 1
The cross-sectional area in secondary wind channel 4, to increase the flow of First air and Secondary Air；
When burner needs to run at low load, control executing agency 7 and control executing agency 5 control outer tube respectively
Rearwardly direction axial movement and Outer Tube wall 1 increase First air channel 2 and two to road wall 28 to cephalad direction axial displacement
The cross-sectional area in secondary wind channel 4, to reduce the flow of First air and Secondary Air.
Compared with prior art, burner apparatus of the present invention adjusts combustion using axially movable set tube wall principle
The cross-sectional area of burner circulation passage can significantly be adjusted operating load, had compared with burning is stablized under underload
Effect adapts to the needs of thermal power plant's flexibility peak regulation under regenerative resource online background.
Description of the drawings
Fig. 1 is the structural schematic diagram of the burner of the adjustable load of the present invention.
Specific implementation mode
The embodiment that the present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, there are three channel, center wind duct 1, First air channels altogether for the burner of the adjustable load of the present invention
2, secondary air channel 4.First air channel 2 is in the centre of center wind duct 1 and secondary air channel 4.First air channel 2 and coal dust
Channel 3 is connected to, and conveys fuel for combustion apparatus, center wind duct 1 and secondary air channel 4 are that combustion apparatus conveys air.Once
There is spinning disk 12 in wind channel 2 and secondary air channel 4, can fuel and air uniformly be mixed, flameholding.
The tube wall of duct wall center wind duct 1 is nested connection group by Outer Tube wall 1 and fixed inner duct wall 1
Be made of the connection that is nested of Outer Tube wall 28 and inner duct wall 26 at the outer tube wall of, secondary air channel 4, secondary air channel 4 it is interior
Tube wall and the outer tube wall in First air channel 2 are fixed duct wall 9.Outer Tube wall 28 does axis by controlling executing agency 27
To displacement, the Outer Tube wall 1 does axial displacement by controlling executing agency 5, and duct wall 9 is fixed.
Since the head of Outer Tube wall 28, duct wall 9 and Outer Tube wall 1 is in shrink mouth shape, then Outer Tube wall 28
Axial displacement is done relative to duct wall 9 with Outer Tube wall 1, the transversal of the 4 of First air channel 2 and secondary air channel can be made
Area changes.
The course of work of burner is, when burner needs to run under high loads, controls executing agency 7 and control is held
Row mechanism 5 can control rearwardly axial movement of the Outer Tube wall 28 to head axial movement and Outer Tube wall 1 respectively, increase
The cross-sectional area in big First air channel 2 and secondary air channel 4；To increase the flow of First air and Secondary Air；Work as burner
When needing to run at low load, control executing agency 7 and control executing agency 5 can control Outer Tube wall 28 to tail respectively
Portion, which is moved axially, to be moved axially with Outer Tube wall 1 to head, and First air channel 2 and the cross section of secondary air channel 4 are reduced
Area；To reduce the flow of First air and Secondary Air, to ensure that stablizing for burner is burnt.
The burner can comply with combustion apparatus load variations and directly make a change, simple in structure, easy to implement, meet
The requirement that thermal power plant's flexibility is adjusted.
