Analyzer for measuring boilers and process heater efficiency
ABB Measurement & Analytics’ Endura AZ40 analyzer is designed to measure the efficiency of fossil-fired boilers and process heaters used in power generation, incineration, petrochemical, and iron and steel production. The analyzer simplifies fine-tuning combustion processes for increased efficiency, lower fuel costs, and reduced NOx pollution and is suitable to operate in temperatures up to 1650 C (3000 F). ABB’s Endura AZ40 analyzer uses two sensors to continuously monitor 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 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. 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. Other features include a heated manifold designed to avoid acid corrosion of the sensor assembly. Advanced diagnostic and verification functions ensure proper analyzer operation through regular self-checks on critical variables.
