Above-mentioned technical proposal of the present utility model is understood for convenience, below by way of new to this practicality in specifically used mode
The above-mentioned technical proposal of type is described in detail.
Control system is mainly made up of five big critical pieces, is respectively：Frequency converter, programmable controller 2（PLC）, touch
Screen 1（HIM touch-screens）, analog module 3（AD/DA modules）, auxiliary reclay 4 etc..
Control system, which has two switch boards, includes dynamic power distribution cabinet（Numbering is AC01）And PLC control cabinet（Numbering is
AC02）.
Programmable controller 2 connects touch-screen 1 by PPI communication cables, and operating personnel are started by point touching screen to press
Button sends enabling signal to programmable controller 2, and programmable controller 2 receives startup order and starts to start accordingly by setting procedure
Equipment, i.e., output control signal is to frequency converter（Including the first frequency converter 5, the second frequency converter 11）With auxiliary reclay 4, and pass through
Auxiliary reclay 4 starts relevant device, such as：Air-introduced machine 8, air blower 9, feed pump 10 etc., analog module 3 is by receiving boiler
The signals such as temperature, pressure and the water level of each measuring point simultaneously feed back to each signal in PLC, and PLC detects that the change of each signal comes automatic
Regulation and the output of control relevant device, such as：The frequency size of frequency converter is adjusted, to reach the purpose of systems stabilisation operation；If
The some spot temperatures of boiler, pressure or water level abnormality, PLC can send alarm signal automatically by audible-visual annunciator 20, and touch
Touch screen 1 and point out warning message, the warning message that operating personnel can point out according to touch-screen 1 performs arrestment and runs and overhaul
Boiler relevant device, the data of system operation are stored in touch-screen 1, and operating personnel or plant engineering technical staff can pass through
The reason for information such as data record, the alarm logging that touch-screen 1 is preserved judge and maintenance boiler goes wrong, therefore transport boiler
The easy to operate stabilization of row, easy to maintenance quick, intelligentized control method is energy-efficient.
Boiler load regulation is realized by burner, steam pressure sensor and Steam pressure control device.Adjusted in boiler load
Before section, it is necessary to first confirm that fuel pressure is normal, just allows to be operated.
（1）Firstly the need of the parameter related to spatial load forecasting is configured, such as：Steam pressure control parameter is joined with boiler
Number.
（2）After parameter setting is finished, first select fuel that the burner of boiler implosion cabinet 7 is switched into auto state.
Load Regulation will be controlled in the following manner automatically：
1）When steam pressure is less than upper limit set value, start burner；Under unfaulty conditions, it can be manually pressed by touching
Blowing out key on screen 1, burner stops.
2）After normal operation, when steam pressure is less than lower limit set value, burner starts；When steam pressure is higher than the upper limit
During setting value, burner stops.
3）After burner is normally run, steam pressure is less than when turning pressure ignition, and load runs for big fire, is pressed higher than fire is turned
Switch to small fire operation during power.
The burner of boiler implosion cabinet with switching under auto state, can manually carry out big/small fire switching manually.
When boiler is by can occur catastrophe failure chain reaction under following situations：Steam super-pressure failure, boiler water shortage failure,
Leak detection failure failure, the flame-out failure of burner, blower fan overload；When fuel is combustion gas, failed by gaseous-pressure exception and leak detection
Interlock protection.
When specifically used：
1）Select current combustion device mode of operation：When manual, burner is directly initiated, and operating personnel need boiler to grasp
Switch to manual mode.
2）When Load Regulation selection is manual, Load Regulation is controlled manually, and selection is automatic by PLC internal controls.
3）When boiler is in PLC state of a controls, boiler attendance is, to auto state, to set open furnace pressure as requested
Power, goal pressure, blowing out pressure, superpressure blowing out, tail cigarette is alarmed, the parameter such as tail cigarette superelevation blowing out, is pressed by the startup on touch-screen 1
Button, boiler operatiopn, burner will carry out PID loads after starting according to PLC controls and increase reduction automatic running.
4）When feed pump 10 selects auto state, feed pump 10 is automatically controlled according to ball float control, and feed pump selection can be
Switch between 1# feed pumps, 2# feed pumps and 0；Not termination of pumping when feed pump is manual.
5）During burner malfunctions, first by the burner SR on touch-screen 1, then boiler startup button is pressed, boiler is extensive
Multiple operation.
In summary, by above-mentioned technical proposal of the present utility model, modular arrangement, quick, extension easy to maintenance and
Communication function is powerful, improves huge conventional relay gasification boiler Control system architecture complexity, maintenance trouble, the simple nothing of function
The defects such as method expanded function；With automaticity is high, easy to operate, control stabilizing energy-saving, man-machine interface image conversion shows and led to
The labor intensity of the understandable reduction workman of custom and maloperation, overcome conventional relay gasification boiler control system automaticity
Low, complex operation fallibility, control unstable to be unable to reach the defects such as energy conservation object.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw under enlightenment of the present utility model
Other various forms of products, however, make any change in its shape or structure, it is every that there is same as the present application or phase
Approximate technical scheme, all falls within protection domain of the present utility model.
