Description
Technical field
The present invention relates to a kind of biomass ratio formula combustion control system.
Background technology
Biomass combustion machine is that a kind of biomass high-temperature using organic biomass such as biological particles as fuel cracks burning
Machine.The efficiency of combustion of boiler, is mainly reflected in air distribution and quantity combusted, if intake is too big, the air for just having surplus neutralizes
Heat in burner hearth so that fire box temperature reduces, the fixed carbon incomplete combustion in fuel, boiler slag carbon content increase, boiler
The thermal efficiency declines；If intake is less than normal, fuel cannot fully burn, and produce a large amount of carbon monoxide, directly be arranged without burning
Go out, make fuel combustion incomplete, cause to waste.Therefore, it is necessary to temperature in burner hearth is monitored to control air quantity.
The content of the invention
In view of the foregoing drawbacks, it is an object of the invention to provide a kind of simple in structure, by monitoring fire box temperature and pressure,
The rotating speed of air blower and air-introduced machine is controlled, ensures that fixed carbon burning is abundant, improves heat utilization efficiency, a kind of biomass of economizing on energy and electricity
Proportion expression combustion control system.
The technical solution adopted in the present invention is for this：
Including power supply, PLC controller, PLC control modules, thermal module, air blast frequency converter, charging frequency converter and air inducing frequency conversion
Device, the power supply are connected with battery main switch, and the battery main switch is also associated with blower switch, air-introduced machine switch and charging
Motor switch, the PLC controller, PLC control modules and thermal module three interconnect and are connected with power supply, described
PLC controller is connected with touch-screen, and the air blast frequency converter, charging frequency converter and air inducing frequency converter are connected with touch-screen respectively.
Further as above-mentioned technical proposal is improved, and the supply voltage is 24V.
Further as above-mentioned technical proposal is improved, and controlling switch is equipped between the battery main switch and power supply.
It is an advantage of the invention that：
The configuration of the present invention is simple, by monitoring fire box temperature and pressure, controls the rotating speed of air blower and air-introduced machine, ensures fixed carbon
Burning is abundant, improves heat utilization efficiency, economizing on energy and electricity.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
A kind of biomass ratio formula combustion control system, including power supply, PLC controller, PLC control modules, thermal module,
Air blast frequency converter, charging frequency converter and air inducing frequency converter, the power supply are connected with battery main switch, and the battery main switch also connects
It is connected to blower switch, air-introduced machine switch and charging motor switch, the PLC controller, PLC control modules and thermal module three
Person interconnects and is connected with power supply, and the PLC controller is connected with touch-screen, the air blast frequency converter, charging frequency converter
It is connected respectively with touch-screen with air inducing frequency converter.
Further as above-mentioned technical proposal is improved, and the supply voltage is 24V.
Further as above-mentioned technical proposal is improved, and controlling switch is equipped between the battery main switch and power supply.
With following functions：
1st, manual automatic function：System control departure is moved and automatic control mode, can be pressed when manual by the start and stop on operation console
Button controls the start and stop of each motor, and can adjust the speed of service of each motor manually by potentiometer；Adopted during automatic control mode
With PLC and touch-screen, according to pre-set program automatic running.
2nd, permanent vacuum cavitations：The actual suction pressure in biomass combustion system vaporizer or boiler furnace is detected in real time, and is turned
Become electric signal and be sent into PLC, when air blast is because of external load degree, sensor will detect vaporizer or boiler furnace negative pressure
Change, computer compared with setting negative pressure, export a control signal and give air inducing frequency converter, adjust according to actual suction pressure measured value
The rotating speed of air-introduced machine, makes negative pressure be returned to setting value, so as to remain the constant of vaporizer or boiler furnace negative pressure.
3rd, continuous burning mode：Using advanced converter technique, micro computer computer technology, needs according to the load of boiler
Automatic adjustment charging（Biological particles）Speed, while air blast, post-blast, an air inducing are controlled according to wind fuel ratio curve
With the rotating speed of charging motor, the burning dynamics of biomass combustion machine is set to be changed according to the change of load, burning time is elongated, combustion
Material burning-up is grilled thoroughly, simultaneously because air inducing, blast velocity are slack-off, flue gas flow rate is slack-off in flue, in red-hot flue gas and heat exchanger
The heat exchanger time of heating agent is relatively elongated, and exhaust gas temperature is relatively relatively low, and heat utilization efficiency becomes higher.
