New oxygen and combustibles analyzer
ABB has launched a new oxygen and combustibles analyzer for measuring the efficiency of fossil-fired boilers and process heaters used in power generation, steam generation plants, incineration, petrochemical and iron and steel production applications. Replacing ABB’s SMA90 system, the AZ40 analyser incorporates a range of features enabling users to easily and accurately fine-tune their combustion processes to improve efficiency, lower fuel costs and reduced production of nitrogen oxides (NOx). The AZ40 analyzer monitors both the oxygen and the unburned combustibles in terms of carbon monoxide equivalent (COe) using two sensors. The oxygen reading indicates the percent by volume measurement of the net oxygen. Typically, this reading is the primary indicator for combustion control.
