Profession background
Our country with hotly picks mines the thick oil to have
more than 20 years, at present our country uses the note boiler
furnace is the overseas 60's technology, its control mode or depends
on the manual hand control, namely the basis artificial each hour
analyzes time does, artificial adjusts 火量, achieved the
maintenance request the steam does, the original fuel air compared to
the automatic tracking loop, as a result of the fuel quality change,
has completely not been able to achieve best burning, the excess air
is big, creates the massive energys waste, based on the above reason,
newly develops the development "the note boiler furnace automatic
control system" it to be able the automatic detection steam to do,
automatic control 火量, Throughout maintains the request the
steam to do, simultaneously, automatically carries on the haze
analysis, automatically matches the wind, throughout maintains best
burning, the maintenance most high fever efficiency, the energy
conservation rate may achieve above 5%, uses LEODO to insert the type
man-machine contact surface automatic control note boiler furnace to
be able to guarantee the steam quality and best burning, enhanced the
equipment use benefit, is advantageous to the energy conservation and
the environmental protection, has the renewal the vital significance.
System introduction
This system used LEODO to insert the type man-machine
contact surface and Matushita FP series PLC has completed the note
boiler furnace automatic control system. This system has the
following function:
This system mainly is composed by 8 pictures.
1. Boiler flow chart
May observe the main movement parameter and the output
controlled variable from the flow chart.
2. The boiler controls the charting
Some three groups of good charts, namely do a control
(火量 control) with the oxygen quantity control (amount of wind
control), the fuel pressure control (fuel flow control) in the chart
the given value (has numeral or spot by the manual input tows two
ways), the output control signal has manual and the automatic two
control mode, clicks on the change-over switch perform handover, is
automatic when manual does not play the role.
3. Craft parameter
Demonstrates 16 parameters
4. Ignition succession
Has demonstrated the hot note stove 120 seconds ignition
successions chart.
5. Reports to the police the instruction
Demonstrated the hot note stove 18 items report to the
police
6. Reports to the police the record
The recording reports to the police the time content
7. Historical curve
Some four curves: Does, the steam pressure, the
vapor temperature, gives the fluent quantity predicted value
8. System administration:
Is when the system movement does not have to have frequently to
operate with the picture which watches, must have the specialist to
input the password only then to allow to open the operation. |
