ABB Introduces Endura AZ40 Analyzer

ABB introduces an oxygen and combustibles analyzer for measuring the efficiency of fossil-fired boilers and process heaters used in power generation, incineration, petrochemical and iron and steel production. Replacing ABB’s SMA90 system, the Endura AZ40 analyzer simplifies fine-tuning combustion processes.

Using two sensors, ABB's Endura AZ40 analyzer continuously monitors combustion waste gases to measure both excess air and unburned fuel. The analyzer provides an unburned fuel measurement in terms of carbon monoxide equivalent (COe). The COe reading supplements the net oxygen measurement to permit further trimming of combustion efficiency.

The analyzer consists of a sensor assembly, probe with filter assembly, transmitter and interconnecting cable. The sensor assembly mounts to a duct or process wall  with the probe extending into the flue gas stream. Available in lengths up to 8+ feet (2.5 meters) and suitable for temperatures to 3,000°F (1650°C), the probe continuously draws in the sample for analysis. Automatic sensor calibration uses test gases of known concentrations to calibrate both sensors and ensure continuous accuracy, according to the company.

High efficiency filters and optional blowback prevent clogging of the Endura AZ40 probe head filter.  A heated manifold avoids acid corrosion of the sensor assembly. Advanced diagnostic and verification functions reportedly ensure proper analyzer operation through regular self-checks on critical variables. The analyzer's HMI shares the same look and feel as ABB’s other instrumentation. Users can access, program and adjust settings and operational data from one screen. The Endura AZ40 analyzer is fully backwards compatible and can be retrofitted in the field to ABB’s previous generation of SMA 90 combustibles analyzers.
