IM 11M12D01-01E

3rd Edition

Introduction

The EXAxt Series AV550G Zirconia Oxygen Analyzer Averaging Converter is designed for oxygen measurement at multiple points in flue ducts of industrial furnaces and can be used to optimize the combustion process. For the AV550G system, various types of EXAxt ZR Series detectors as well as optional accessories are available. The best measurement can be achieved by selecting instruments appropriate to your application.

This manual provides information, such as installation, operation, inspection and maintenance procedures, about the instruments used in the AV550G averaging converter measurement system. Any sections concerning instruments not included in your system may be skipped.

Before using the instruments, read any descriptions related to your instruments and system to ensure the best performance.

Regarding the HART communication, refer to IM 11M12D01-51E. IM 11M12D01-51E has been published as "Model EXAxt AV550G HART protocol."

Regarding the FOUNDATION Fieldbus communication, refer to IM 11M12D01-61E. IM 11M12D01-61E has been published as "Model EXAxt AV550G Fieldbus communication."

r For the safe use of this equipment

CAUTION

The cell (sensor) at the tip of the detector is made of ceramic (zirconia element). Do not drop the detector or subject it to pressure stress.

• Do NOT allow the sensor (probe tip) to make contact with anything when installing the detector.

• Avoid any water dropping directly on the probe (sensor) of the detector when installing it.

• Check the calibration gas piping before introducing the calibration gas to ensure that there is no leakage of the gas. If there is any leakage of the gas, the moisture drawn from the measured gas may damage the sensor.

• The detector (especially at the tip) becomes very hot. Be sure to handle it with gloves.

DANGER

AV550G is very heavy. Handle it with care. Be sure not to accidentally drop it. Handle safely to avoid injury.

Connect the power supply cord only after confirming that the supply voltage matches the rating of this equipment. In addition, confirm that the power is switched off when connecting power supply.

Some process gas is dangerous to people. When removing this equipment from the process line for maintenance or other reasons, protect yourself from potential poisoning by using a protective mask or ventilating the area well.

When carrying the AV550G Averaging Converter, mark sure this is done by two or more people.

1. Overview

Zirconia oxygen analyzers are used in combustion facilities to measure the flue gas oxygen concentration. Boiler operators use the oxygen measurement to optimize fuel usage, minimize atmospheric emissions and reduce energy consumption.

A multiple point oxygen measurement system may be required for situations when gas stratification in the flue duct affects combustion control. The AV550G Averaging Converter can accept inputs from up to eight zirconia oxygen detectors. It sends output signals for the individual as well as averages of multiple oxygen concentrations. A robust multipoint converter reduces installation and maintenance costs.

A large 5.7-inch color LCD display shows various measurement, setup, calibration, and trend screens. Its intuitive touch screen is easy to read and makes set up and maintenance simple. Other standard features include new self-diagnostics and a hot swap function that allows a desired probe to be disconnected/reconnected for inspection or maintenance just by turning off the power of the relevant channel.

The ZR22G separate-type detector uses a highly reliable zirconia sensor and its heater assembly can be replaced in the field. The in situ probe is mounted on the duct wall and directly measures the oxygen concentration of a sample gas at a temperature of up to 7008C. For higher temperature applications up to 14008C, the ZO21P-H High Temperature Probe Protector is available for use in conjunction with a 0.15-m ZR22G general-purpose detector.

1. Overview

The averaging converter system is ideal for combustion control in large utility boilers or various industrial furnaces.

This chapter explains system configurations with some typical examples.

1.1 System Configuration

The AV550G Zirconia Oxygen Analyzer Averaging Converter system can be configured by selecting detectors and an averaging converter that meet the individual requirements and flow setting units for calibration.

Subsection 1.1.1 presents a typical system configuration using flow setting units for manual calibration. A typical system configuration to perform automatic calibration is provided in Subsection 1.1.2.

1.1.1 System Configuration Using Flow Setting Units for Manual Calibration

This system consists of detectors, an averaging converter, and flow setting units (Model ZA8F), as shown in Figure 1.1. Note that the ZA8F Flow Setting Units are required as many as the detectors connected to the averaging converter.

A reference gas needs to be supplied at a constant flow rate to the detectors. This reference gas must be clean, dry air having a constant percentage of oxygen. Typically, instrument air that has been dehumidified down to a dew point of approximately -208C and is free from oil mist or dust, is used as the air source. This air is also used as a span gas for the detectors during calibration. A zero gas for calibration is supplied from a cylinder to the detectors.
