ZO-303
zirconia oxygen content analyzer (constant temperature type) consists of
two parts: an |
|
analyzer and a flue oxygen
sensor. It is suitable for measuring the oxygen content in the furnace
|
|
and flue of various boilers,
kilns, petrochemical power plants, etc. that need to be heated and
|
|
combusted with coal, oil, and
other substances. If matched with automatic control devices, it can
|
|
instantly and effectively
control the flue damper, throttle, damper, etc. ZO-303 zirconia oxygen
|
|
content analyzer has a
significant role in improving combustion efficiency, saving energy, and
|
|
reducing pollution. |

◆
The oxygen transmitter adopts intelligent single-chip microcomputer and
dedicated module circuit design, with high calculation and
|
|
control accuracy and good stability, fully meeting the requirements of
the DCS system; |
|
◆
The instrument
calibration adopts a two-point calibration method, which can
independently adjust the zero point and range to ensure the |
|
measurement linearity of the
full range; |
|
◆
The instrument has a
couple breaking protection function; Unique overall design, easy to
operate, and low maintenance. |
|
◆
Programmed heating to
avoid sensor damage and furnace burnout due to excessive heating; With a
temperature sensor, it automatically |
|
corrects and compensates for
oxygen content errors caused by ambient temperature fluctuations |

(1)
Energy conservation; (2) Reduce environmental pollution; (3) Extend
furnace life. |
|
In the
process of furnace combustion, when the air excess coefficient is too
small, that is, the oxygen content is insufficient, the thermal |
|
efficiency decreases due to
incomplete combustion of the fuel. At the same time, the chimney emits
black smoke, causing significant |
|
environmental pollution. When
the air excess coefficient is too large, that is, too much oxygen, the
excess air carries away too much heat, |
|
which also leads to low thermal
efficiency. At the same time, excessive oxygen can lead to an increase
in the content of SO2, SO3, and NOX |
|
in the flue gas, which on the
one hand causes serious pollution to the environment, and on the other
hand, SO2 and SO3 can also corrode |
|
the tail of the boiler.
Therefore, controlling the oxygen content within a reasonable range can
not only improve the thermal efficiency of the |
|
fuel, play a role in saving
energy, but also reduce the environmental pollution caused by exhaust
gas and the corrosion of SO2 and SO3 on |
|
the boiler tail, extending the
furnace life. The zirconia oxygen analyzer can monitor the oxygen
content in the flue gas online and real-time, |
|
and directly feed back the
monitored oxygen content value to the combustion control system,
controlling the oxygen content within a |
|
reasonable range, thereby
achieving the above objectives. |
