In PLC, PLC detects the output for changing to automatically adjust and control relevant device of each signal, such as：The aperture of control control valve 8,
To reach the purpose of systems stabilisation operation；If boiler some spot temperatures, pressure or oil level exception, PLC can be by sound and light alarm
Device 5 sends alarm signal automatically, and warning message is pointed out on touch-screen 1, and operating personnel can be according to prompting on touch-screen 1
Warning message performs arrestment and runs and overhaul boiler relevant device, and the data of system operation are stored in touch-screen 1, operation
The information such as data record, the alarm logging that personnel or plant engineering technical staff can be preserved by touch-screen 1 judge and overhaul
The reason for boiler goes wrong, therefore make the easy to operate stabilization of boiler operatiopn, easy to maintenance quick, intelligentized control method is efficiently saved
Energy.
Outlet pressure sensor 19, inlet pressure sensor 20 are used to detect the pressure that burner hearth is imported and exported.Air blow down valve
12nd, steam blowing valve 13 is used to control intake, and atomization air valve 14 is used to control the flow of atomizer, and lighting valve includes two
Lighting valve is 1# lighting valves and 2# lighting valves.Circulating pump 23 is 1# circulating pumps, 2# circulating pumps including two circulating pumps.
Boiler load regulation is realized by burner, outlet pressure sensor 19, inlet pressure sensor 20 and main fuel tap 11.
Before boiler load regulation, 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 and boiler parameter.
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, 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 normally runs, less than when turning pressure ignition, load runs steam pressure for big fire, is pressed higher than fire is turned
Switch to small fire operation during power.
Burner can switch with auto state manually, can manually carry out big/small fire switching.
Will be manually operated（Pump group 10）It is automatic mode to select, in the state of system detectio fault-free, by start button
Starting trouble igniting operation, normal combustion program is entered if lighting a fire successfully, chain blowing out of being alarmed if igniting is unsuccessful, is checked
Questions and prospect and release can starting trouble after failure.
Boiler is interlocked by following situations；Oil temperature superelevation failure, oil pressure superelevation failure, fuel oil temperature are low, the flame-out event of burner
Barrier, return pressure failure high, blower fan overload；
In sum, 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 waste material thermo oil boiler Control system architecture complexity, maintenance trouble, safety interlocking
Function imperfection and cannot the defect such as expanded function；Perfect, easy to operate, control is protected with high degree of automation, safety interlocking
Stabilizing energy-saving processed, man-machine interface image conversion show it is easy-to-understand reduction workman labour intensity and maloperation, improve in the past after
Electric-type waste material oil cauldron furnace control system automaticity is low, safety interlocking imperfection, complex operation fallibility, control it is unstable cannot
Reach the defects such as energy conservation object.
