In combustion applications such as process heaters,steam generation boilers or furnaces, the amount of airneeded to reach optimum system efficiency can varyrapidly. The optimum heat rate for these units, which maylie within narrow limits, can be achieved with the BA2000.Accurate O measurement is also essential in the controlof NO and emissions. Equipped with a fast esponding sensor and attached directly to the fire box,this analyzer provides immediate information to allow

adjustment of the combustion process in real-time.The BA 2000 is designed to ensure accurate and rapid measurement in most combustion processes. The uniquefast loop design continuously provides a fresh sample gasstream to the zirconium oxide sensor. The sensorenclosure is heated to 350°F to avoid condensation. Thezirconium oxide sensor does not need any reference gas.1-point-calibration of the sensor takes place withinstrument air which is also used for the aspirator driving the sample gas. Optionally, a 2-point-calibration may be performed.
