Combustion

The Endura Combustion Gas Oxygen Analyzer AZ20 is the latest in a long line of high-quality, combustion gas analyzers from ABB. The sensor, based on a zirconium oxide cell, is mounted at the tip of the probe that is inserted in the flue duct. The resulting direct, in situ measurement provides accurate and rapid oxygen reading for combustion control optimization and emissions monitoring.

The Endura AZ25 is an in situ combustion gas oxygen analyzer system designed for use in high temperature applications > 600 degrees C. The sensor, based on a zirconium oxide cell, is mounted at the tip of the probe that is inserted into the furnace or flue duct. The resulting direct, in situ measurement provides accurate and rapid oxygen reading for combustion optimization, process control and furnace atmosphere monitoring.

ABB's NEW Oxygen & Combustibles Analyzer, Endura model AZ40, is a microprocessor based industrial grade combustion analyzer that continuously samples and analyzes industrial flue gases (oxygen only or optional oxygen and combustibles).The analyzer is designed for use on gas, oil or coal fired combustion processes and has a high temperature operating range.Typical applications include those found in the utility and petrochemical industries.

The 9610 calorimeter measures Wobbe Index, BTU/Heating Value and CARI (Combustion Air Requirement Index).  Key advantages of this calorimeter is its insensitivity to changes in ambient temperature, a very fast response with the ability to measure gases with BTU values down to zero and the measurement of the Combustion Air Requirement Index besides Wobbe Index and Heating Value.

Reliable flow measurement for hot and dust laden gases - single channel solution

The McON Air Compact flow measurement system is a single channel solution which works according to a patented correlation principle. The system measures the time of flight of unique signal patterns created by particles contained in the gas. Because the principle is time based it is accurate and drift free over the entire lifetime.

Advantages & Benefits

• Reliable measurement of dust laden gases
• Temperature range up to 1000 °C/1800 °F
• Drift free - no calibration, no purging
• Virtually no maintenance
• Turn down ratio up to 25
• No K-Factors - direct time of flight measurement Hot tapping solution for full plant availability
• Even for emission monitoring: Most accurate measurement of the total stack flow

The McON IR flow measurement system is a single channel solution which works according a patented correlation principle. The system measures the time of flight of unique signal patterns created by particles contained in the gas. Because the principle is time based it is accurate and drift free over the entire lifetime.
