An SPS-control system for the complete PYRTEC Boiler Plant, incl. control of the systems for the fuel loading necessary
for the articles listed separately. The heat output of the furnace adjusts to the heat consumption in modulating fashion. A
regulating circuit for an incineration optimising system is superimposed on the output control circuit with a lambda sensor.
Maximum quality criteria are met in terms of fire protection and personal protection.
Functions:
- Output and control circuits with modulating output operation (25%-100%)
- Air-conducted by means of a speed-regulated supply air fan, depending on the forward flow temperature
- Precise resupplying of fuel by the feed auger from the metering container with an isolating layer
- Refilling of the metering container with the use of a level monitoring system
- Limitation and distribution of the mass burning in the fire box by means of a level monitoring system in the
fire box along with movement of the feed grate
- Emissions-optimised control circuit with fine tuning of the fuel/air mixture by a lambda sensor
- Pressure regulation of the fire box with constant negative pressure guaranteed
- Fire box temperature limitation with the required variation of the air index to protect the fire-resistant lining
- Upholding the return flow temperature with the boiler mixer provides for a long service life of the boiler.
- Safety functions for:
Excess temperature, burn-back, opening of the fire box door, opening of a lid in the loading system, excess
pressure in the fire box
- Floating output (malfunction indication system)
Operation:
Operation is carried out by means of a control panel with a membrane keyboard and plain language display, which are
built into the control cabinet door. All the operational data can be read on the display.
The set points for all the important parameters can be entered simply using the keyboard. Malfunctions are displayed in
plain language and indicated in the order of their occurrence.
The following items come with the system:
- Control cabinet (uninstalled), surface powder-coated with RAL 7035 (grey) textured
Executed according to ÖVE/VDE-guidelines, ready-wired on series terminals,
Feed: 3x400 V 50 Hz; control voltage: 230 V or 24 V
- Freely programmable control system, CE-inspected, programme and real-time clock are battery-backed
- Motor contactor switch for all drives according to the separate items priced separately
- Frequency converter for fan motors
- Protective motor switch for boiler pump
In the door:
- 4-pin master switch
- Control panel with back-lit plain language display
- Documentation, incl. bound circuit diagram, terminal connection diagram with cable designation,
operating and maintenance instructions, installation instructions in document sleeve
