ZO-300
in-line zirconia probe is suitable for boilers, kilns, petroleum,
chemical, power plants, |
|
and other furnaces and flues
that require coal, oil, and other fuels for heating and combustion.
|
|
This instrument can accurately
and quickly reflect the instantaneous oxygen content during furnace
|
|
combustion, and can timely and
effectively control the flue damper, throttle, damper, etc. It has a
|
|
significant role in improving
combustion thermal efficiency, saving energy, and reducing pollution.
|
|
The flue at the insertion point
of the ZO-300 in-line zirconia probe must have a negative pressure
|
|
because the reference gas of
the zirconia probe is air, which flows naturally in the flue Only
under negative pressure can the air intake probe generate electric
potential. Zirconia probes have three |
|
main functions: |
|
(1) Saving energy (2) Reducing
environmental pollution (3) Extending furnace life |
|
◆The
core component - zirconium oxide head, with small internal resistance
and fast response speed. |
|
◆Zirconia
components are designed to reduce stress, improving the seismic
resistance and mechanical strength of the components, |
|
reducing the possibility of
fracture; |
|
◆The
surface of zirconia electrode has undergone special processing, which
can improve the measurement sensitivity, service life, and
|
|
corrosion resistance on the
original basis; |
|

|
This zirconia probe is widely used to monitor the oxygen concentration
of combustion gases in large or small boilers, power plant |
|
boilers, various industrial
furnaces, and combustion devices, or to control low oxygen combustion
and monitor the oxygen content in |
|
exhaust gas from various
combustion systems, in order to achieve low oxygen rational combustion,
reduce fuel consumption, burn loss, |
|
stabilize processes, improve
product quality, and reduce environmental pollution. Wide application
range and fast response speed of the |
|
product |
