Transcription

1 IN-SITU IRCONIA OXYGEN ANALYER DATA SHEET FK8, KM, TA This oxygen analyzer is used to continuously measure oxygen concentration in combustion exhaust gas of industrial boilers furnaces, and is ideally suited f combustion management and control. The analyzer system is comprised of the detect and converter coupled together as a complete system. Detect setting configuration includes the detect flow guide tube and detect sens. The flow guide tube is inserted directly into the gas and directs gas to the sens f measurement. The converter (KM) is comprised of the signal process, input/ and communications, display and system controls. The converter is equipped with advanced functionality such as perfming the sens diagnostics and sens recovery function, so the detect can be used within long term stability. General-use detect (FK8) High-temperature detect (TA) FEATURES. Gas sampling device is unnecessary F quick response, insert the detect directly into the flue Gas sampling functions such as a gas aspirat and a dehumidifier are not required.. Easy maintenance The sens equipped with the detect, has unit construction, it is easy to replace. By separating the detect and the flow guide tube, filter replacement is easy.. Me reliable than sens diagnosis, sens recoverable function Depending on the concentration of the measurement gas, the power of the sens might deteriate. The equipment includes sens recovery function electronically, checking the deteriation status of the sens depletion. Therefe, it has high reliability and long-lasting stability. 4. Safe and secure System detects thermocouple break f heater control on the sens side. Safety functions of isolating power to the detect isolating power via external input are also.. Easy operation The operation and setting f the converter can be perfmed interactively, and available as English, Japanese Chinese f language display. <IP66> Converter (KM) SPECIFICATIONS <IP67> Converter (KM) General Specifications Measuring object: Oxygen in noncombustible gas Measuring method: Directly insert type zirconia system Measuring range: 0 to setting range at option in 0 vol% O (in vol% O steps) Repeatability: Within ±0.%FS Linearity: Within ±%FS Response time: Within 4 to 7 sec, f 90% (from calibration gas inlet) Warmup time: Me than 0 min Analog : 4 to 0mA DC (allowable load resistance less than 00W) 0 to V DC ( resistance me than 00W) Power : Rated voltage; 00 to 0V AC (operating voltage 90 to V AC) 00 to 40V AC (operating voltage 90 to 64V AC) Rated frequency; 0/60Hz Power consumption: Maximum 40VA (Detect: approx. 00VA, Converter: approx. 40VA) Typical 70VA (Detect: approx. 0VA, Converter: approx. 0VA) EDSX-7e Date Oct. 0, 0

The inclusion of crosive gas (Si vap, alkaline metal, P, Pb etc.) will shten the life of the sens. When the measured gas temperature is high (+00 C higher), the flange should be separated from the furnace wall in der to bring the detect flange surface temperature below the specified value + C). The flow guide should be attached in the direction in which the gas flow to the detect decreases. When much dust is included in the gas, the flow guide tube should be attached at an inclination so that the flow goes from below to above. And the flow guide tube should be attached in the direction in which the gas flow to the detect decreases. In the case of a refuse incinerat, automatic blow down of the flow guide should not be perfmed (to prevent crosion of the flow guide tube due to drainage). Blowdown should be perfmed manually when change in the indication has become very little with the furnace stopped.
