And lambda sensor（4）, the operating status of boiler is judged and by air distribution reality according to the pressure value, temperature value and the oxygen content that collect
Now adjust.
Further, the controller of the controller and boiler induced-draft fan that are located at boiler blower is connected to PLC control cabinet simultaneously
Its running frequency is controlled by controller.
Further, PLC control cabinet（5）Including PLC controller, power module, access knob, power supply indicator, two-way
Relay, wire connection terminal, Industrial touch screen, signal isolation module.
The control method of the industry boiler energy-conservation operation Automatic Optimal control system, step are as follows：（a）Run burner hearth pressure
Power adjustment programme, furnace pressure is adjusted to micro-vacuum state；（b）Furnace pressure decision procedure is run, judges burner hearth operation pressure
Whether power state is normal；Special handling procedure is performed if abnormal.（c）Burning optimization decision procedure is run, judges whether to deposit
In the energy saving space, and recording status, such as without the energy saving space, EP (end of program), otherwise performs next step；（d）Running optimizatin amplitude is sentenced
Determine program, judge whether current optimization amplitude meets setting value, then perform furnace pressure adjustment programme in this way, under otherwise performing
One step；（d）Burning optimization optimizing program is run, according to influence of the air distribution to parameters such as oxygen contents in combustion position and smoke evacuation, is looked for
Go out the operating status of current boiler and carry out the adjusting parameter of energy-saving run；（e）Energy saving in running operating parameter calculation procedure calculates
Go out optimizing parameter；（f）The optimizing parameter calculated is exported to each subsidiary engine of combustion system of boiler；（g）Perform Boiler Furnace gun pressure
Power decision procedure, judges whether furnace pressure is abnormal, performs furnace pressure adjustment programme in this way and be adjusted, otherwise then perform combustion
Burn optimization decision procedure.
Further, the optimizing parameter is specific by the boiler difference type of furnace, tonnage, combustion system and historical data etc.
Parameter calculates the optimizing parameter needed for current procedures.
The industry boiler energy-conservation operation Automatic Optimal control system of the utility model, can find out current state by optimizing
The boiler operating parameter of lower boiler operatiopn most power save mode, and operation to boiler carry out it is energy saving automatically control and adjust automatically,
Boiler combustion is adjusted to the economical and energy saving operation for energy-saving combustion state, ensureing boiler.
