IN-SITU

ZIRCONIA OXYGEN ANALYZER

DATA SHEET

This oxygen analyzer is used to continuously measure oxygen concentration in combustion exhaust gas of industrial boilers or furnaces, and is ideally suited for combustion management and control. The analyzer system is comprised of the detector and converter coupled together as a complete system. Detector setting conﬁ guration includes the detector ﬂ ow guide tube and detector sensor. The ﬂ ow guide tube is inserted directly into the gas and directs gas to the sensor for measurement. The converter (ZKM) is comprised of the signal processor, input/ output and communications, display and system controls. The converter is equipped with advanced functionality such as performing the sensor diagnostics and sensor recovery function, so the detector can be used within long term stability.

FEATURES

1. Gas sampling device is unnecessary

For quick response, insert the detector directly into the

ﬂ ue Gas sampling functions such as a gas aspirator and a dehumidiﬁ er are not required.

2. Easy maintenance

The sensor equipped with the detector, has unit construc-

tion, it is easy to replace.

By separating the detector and the ﬂ ow guide tube, ﬁ lter

replacement is easy.

3. More reliable than sensor diagnosis, sensor recoverable function

Depending on the concentration of the measurement gas,

the power of the sensor might deteriorate. The equipment includes sensor recovery function electronically, checking the deterioration status of the sensor depletion.

Therefore, it has high reliability and long-lasting stability.

4. Safe and secure

System detects thermocouple break for heater control on

the sensor side. Safety functions of isolating power supply to the detector or isolating power via external contact input are also.

5. Easy operation

The operation and setting for the converter can be per-

formed interactively, and available as English, Japanese or Chinese for language display.

CAUTIONS

• If combustible gas (CO, H2 etc.) exists in the measured

gas, error will occur due to burning at the sensor section. The inclusion of corrosive gas (Si vapor, alkaline metal, P, Pb etc.) will shorten the life of the sensor.

• When the measured gas temperature is high (+300°C

or higher), the flange should be separated from the furnace wall in order to bring the detector ﬂ ange surface temperature below the speciﬁ ed value +125°C). The ﬂ ow guide should be attached in the direction in which the gas ﬂ ow to the detector decreases.

• When much dust is included in the gas, the ﬂ ow guide

tube should be attached at an inclination so that the ﬂ ow goes from below to above. And the ﬂ ow guide tube should be attached in the direction in which the gas ﬂ ow to the detector decreases.

• In the case of a refuse incinerator, automatic blow down

of the ﬂ ow guide should not be performed (to prevent corrosion of the ﬂ ow guide tube due to drainage). Blowdown should be performed manually when change in the indication has become very little with the furnace stopped.
