• Display for program status and flame signal intensity

 

Application 1 Application Automatic burner control unit IFD 258 ignites and monitors directly ignited industrial gas burners of unlimited capacity. As a result of its fully electronic design it reacts quickly to various process requirements and is therefore also suitable for frequent cycling operation.

It can be used for atmospheric burners or forced draught burners in multiple burner applications, where a central control system is used for pre-purge and for monitoring. The burners may be modulating or stage-controlled.

The automatic burner control is suitable for operation in grounded and ungrounded systems. The program status and the level of the flame signal can be read directly from the unit. The switch-off threshold can be set using a potentiometer.

The behaviour in the event of flame failure during operation can be selected using a switch. Either an immediate fault lock-out or a restart occurs.

Once the normal operating state is reached, the automatic burner control unit for continuous operation IFD 258 will release control. The PLC can now pulse the air solenoid valve VR..R in order to control the capacity between high and low fire. IFD 258 10 L1, N, PE 3 µC BIO/ BIC VR..R 11 8 9 13 14 4 5 GIK..B VAS BMS IFD 258 ·

Edition 03.12l 8 Application 1.1.3 Modulating-controlled burner Control: ON/OFF/continuous The PLC uses the actuator IC 20 to move the air butterfly valve BVA to ignition position. The burner BIO/BIC starts at low-fire rate. Once the normal operating state is reached, the PLC uses the actuator IC 20 and the air butterfly valve BVA to control the burner capacity.
