EUROX® oxygen sensors for direct insertion are based on a zirconium oxide measuring cell, which measures against reference air from a reference air unit. Together with an active ceramic diffusion block the inner and outer protection tube effect a maximum protection of the inner components.
With an EUROX® measuring system for directly inserted probes the oxygen content in flue gas can be measured reliable and therefore a reliable feedback about the state of combustion is received. In this way, combustion can be optimised, energy can be saved and emissions reduced.
In addition, fluctuations in the heating value can also be detected and thus compensated, resulting in safe furnace operation.
EUROX® REG-System for regenerative end fired (EFF) and cross fired (CFF) furnaces is intended for a reversal of the firing side of the furnace. Short reaction times are realised through adapted construction.
EUROX® system type REG-EFF includes two sensors, for each regenerator chamber one, a reference air unit including all necessary parts for controlling, evaluation and visualising and all required piping between reference air unit and sensors.
The EUROX® REG-CFF-System includes the required number of sensors and one reference air unit for each regenerator chamber. All necessary parts for controlling, evaluation and visualising of the measurement of one side as well as all required piping between reference air unit and sensors is included. The main unit for visualising and controlling the whole measurement system can be one of the two reference air units, but also an additional main unit.
EUROX® system R-O for recuperative and oxyfuel furnaces is the best solution for furnaces without reversal of the firing side. The spotlight in the construction was a maximum protection of the measuring cell.
EUROX® R/O-System includes the required number of sensors, for each flue gas duct one oxygen sensor is recommended. A reference air unit including all necessary parts for controlling, evaluation and visualising and all required piping between reference air unit and sensors is included.
Visualisation of System type REG and System type R/O can be done via visualisation unit of OM-4 and via PLC. Evaluation can be done via OM-4 or via PLC in case of a HORN SCADA system. Adapted to the application and number of probes, all evaluated values are presented.
The following evaluations can be offered:
SENSOR TEMPERATURE IN °C, CELL VOLTAGE IN mV
MEASURED OXYGEN CONTENT IN %
RATIO REAL
FALSE AIR IN %
FLUSHING OBSERVATION
MEMORY MODULE
LAMBDA
CO IN PPM
O2 TREND VALUE IN %
SELF-CHECK MODULE
Both systems are available as a stand-alone and add-on system to a HORN SCADA system and can be offered as purchase offer or rental- and service.
