Description
Technical field
The utility model is related to a kind of boiler burner quadrangle tangential circle measuring device,
Background technology
Boiler corner tangential firing be a kind of coal dust burning, fuel oil, combustion gas boiler, burner hearth is square, boiler burner
The theoretical circle of contact is the important design parameter of fired power generating unit safety and economic operation, and numerical values recited is directly related to furnace air power
The specific distribution of field, and then influence the combustion case in entire stove.If the burner circle of contact is too small, the close spray that liquidates of air-flow
It penetrates, makes combustion instability；, whereas if tangential circle diameter is excessive, cause air-flow deflection is adherent to cause boiler water wall coking；Also may be used
Cause intermediate zone of silence excessive, exiting flue gas velocity field is unevenly distributed, and the increase of the section flue gas temperature difference in turn resulted in hot gas
Temperature, the thermal deviation of reheat steam temperature.Therefore, if quadrangle tangential circle formula boiler spout angle fails to reach design value, it is easy to influence
The flameholding of boiler, and then the safe operation of boiler is influenced, Integrated comparative needs to determine for different types of coal, the different type of furnaces
Appropriate tangential circle diameter.At this stage, due to tangential circle diameter design or adjust it is improper caused by unit safety accident emerge in an endless stream,
Huge hidden danger is brought to the safety in production of electric power enterprise
Current spout adjustment mode relies primarily on manually bracing wire and the mode of the circle of contact is looked for carry out spout adjustment, there is
Very big measurement error, heavy workload, and influence factor is more, measurement data is coarse, therefore it provides one kind is simple, reliably sets
Standby and method accurately measures tangential circle diameter theoretical in stove, there is positive guidance to unit safety, stabilization, economical operation
Meaning.
Utility model content
The utility model aim is to make up the shortcomings of the prior art, provides a kind of simple, quick, measure data precision
High, easy to use boiler burner quadrangle tangential circle measuring device,
The utility model is that following technical solution is realized
To achieve these goals：A kind of boiler burner quadrangle tangential circle measuring device；A kind of boiler burner quadrangle is cut
Circle measuring device；Hoistable platform including riding upon burner hearth center is made of respectively 5 line laser instrument, disk, wherein flat in lifting
Disk is installed at platform center, and the disc centre places laser, places laser between burner on the outside of the disk, open
The infrared ray that laser is sent out measures burner spout central, disk outside, water-cooled wall composition sight alignment, passes through laser
Instrument measurement in a closed series obtains quadrangle diameter of actual tangent circle.Using quadrangle tangential circle measuring device, furnace plane geometric center is easily accurate
Positioning, it is easy to operate, according to only need to adjust burner just can reach requirement, and the side of measurement after theoretical values unlatching laser
Just, error is small, and the deviation of generation is less than the mode that the circle of contact is looked in traditional artificial manual bracing wire.
Superior effect described in the utility model is：
The utility model changes existing steel wire drawing and sets cross line method, avoids measurement error, heavy workload shortcoming, this
Utility model use laser the characteristics of, it is easy to operate it is simple and quick, accurately measure quadrangle tangential circle spray combusting boiler spout angle
And circle of contact size, measurement error is reduced, secondly by 2 lasers are placed outside disc centre, changes traditional artificial manual drawing
Line looks for the mode of the circle of contact, can shorten the construction period, save artificial, high certainty of measurement, ensure the security reliability of boiler combustion.

Laser 3 is put, laser 31 is placed between 2 outside of disk and burner, opens the infrared ray that laser is sent out, measure
Burner spout central, 2 outside of disk, water-cooled wall form sight alignment, and quadrangle reality is obtained by laser measurement in a closed series
Tangential circle diameter.
As shown in Figure 1；Disk 2 is made according to circle of contact inner and outer diameter, disk 2, disk are installed at burner hearth hoistable platform center 1
Laser 3 is placed at 2 centers, according to known burner hearth footage evidence, is opened laser 3 and is measured check and correction all around water-cooled wall and stove
Thorax center, and measure coner firing device same layer horizontal position.Using laser 3 is quick, accurate and high certainty of measurement,
It is error free.
As shown in Figure 2；The diagonal laser circle of contact instrumentation plan of boiler burner quadrangle tangential circle measuring device, device installation
On burner hearth hoistable platform center 1, it is made of respectively disk 2, laser 3,31, garden is cut according to known size of burner hearth and theory
Data measure burner hearth center by opening laser 3, and opening laser 31 according to tangential circle diameter measures diagonal burner spray
Mouth center, disk outside, water-cooled wall form sight alignment, and all lasers unlatchings can quickly and accurately measure quadrangle and cut
Circle boiler burner angle and circle of contact size, reach and synchronously complete measurement function, reduce error, ensure that the safety of boiler combustion can
By property.The diagonal circle of contact of #2, #4 shown in figure measures figure, is not indicated in the diagonal circle of contact measuring method figure of #1, #3, measuring method is pressed
It is completed according to Fig. 2 steps.
Although above-mentioned be described specific embodiment of the present invention with reference to attached drawing, not to the utility model
The limitation of protection domain, on the basis of technical solutions of the utility model, those skilled in the art do not need to pay creative labor
