Oxygen Flue Gas Analyzer
BA 2000
In combustion applications such as process heaters,
steam generation boilers or furnaces, the amount of air
needed to reach optimum system efficiency can vary
rapidly. The optimum heat rate for these units, which may
lie within narrow limits, can be achieved with the BA2000.
Accurate O measurement is also essential in the control
2
of NO and SO emissions. Equipped with a fast
x x
responding 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 unique
fast loop design continuously provides a fresh sample gas
stream to the zirconium oxide sensor. The sensor
enclosure is heated to 180 °C to avoid condensation. The
zirconium oxide sensor does not need any reference gas.
1-point-calibration of the sensor takes place with
instrument air which is also used for the aspirator driving
the sample gas. Optionally, a 2-point-calibration may be
performed.
The measurement cell is protected against dust and
particulates by a heated filter. The filter element can be
easily replaced without tools by a 90° turn of the handle.
Filter elements are available in ceramic, sintered
pleated stainless steel. The BA 2000 can be used with
these filters for dust loads up approx. 2g/m³. When the
dust load exceeds this limit, additional in-situ filters are
available.

The BA 2000 provides all necessary information for safe
operation. The controller has an integrated display with
push-buttons for input, alarm outputs, calibration function
and 4-20mA signal output.
