INFRARED GAS ANALYZER FOR STACK GAS
DATA SHEET
ZSP
This instrument consists of an (or two) infrared gas analyzer(s),
a zirconia O2 sensor and a sampling device. It is used for
measuring the NOx, SO2, CO and O2 components in the flue
gas of various boilers, garbage incinerators, furnaces, etc.
through a selective combination of the components.
The instrument has passed a type approval test in compliance
with regulations on measurement and weighing (specified in
Japan) of each component. It is extensively applicable as a
gas analyzer for environmental pollution control and combustion control.
FEATURES
1. Simultaneous measurement of five components
A combination of two infrared gas analyzers plus a zirconia
0 2 sensor allows simultaneous measurement of four
components, NOx, SO 2, CO, CO2 and O2.
2. Easy operation with multiple functions
This analyzer can be equipped with a number of functions
such as auto calibration, O2 correction and self-diagnosis.
It is easier to operate and maintain than a separate type
calculator system.
3. Little interference from other gases
Measuring error due to interfering gases contained in
sample is nearly zeroed by the Permapure dryer and
interference compensating detector adopted in the analyzer section respectively.
4. Excellent measuring accuracy and stability
The optical system is so constructed as to be free from
external stress by using a single light source and double
beam paths, and therefore assures improved measuring
accuracy plus excellent stability.
5. High sensitivity and wide dynamic range
The infrared gas analyzer, which mounts a mass flow
sensor, has a high sensitivity and a broad dynamic range,
and is capable of switching the measuring range to obtain
1:20 at maximum.
6. Reliable sampling system
Simple but reliable sampling system based on Fuji's rich
experience in the field enables easy maintenance and
reduces frequency of maintenance.

Functions of individual components
• Gas extractor (type ZBA):
With heating type stainless steel filter;
standard diameter 40µm for filter.
• Gas conditioner (type ZBH9):
For separating drain and removing sulfuric
acid mist and oil mist or fine dust particles.
Automatically extractor air to prevent drain
from being sucked when internal pressure
reaches –6.78kPa {–690mmH20}.
• Pump(typeZBG8):
A diaphragm type suction pump to
extractor sample gas (sample gas flow
rate approx. 2L/min).
• Electronic gas cooler (type ZBCA):
An electronic dehumidifier which dries
the moisture in sample gas to a dew
point of approximately 2°C.
A valve for adjusting sample gas flow rate
and to be operated while monitoring the
flowrator on the front panel.
• Converter (type ZDL):
Added to the NOx analyzer. A converter
using a special catalyst which converts
NO2 gas into NO. The catalyst must be
renewed once every year.
Temperature controller is equipped in the
unit.
• Solenoid valve (type; AB21):
Used for introducing calibration gas when
auto calibration function is provided.
• Membrane filter (type ZBBM):
Eliminates fine dust particles with a paper
filter made of glasswool or Teflon, and
permits monitoring dust adhering condition on the front panel of the gas analyzer.
• Flow rotor:
Monitors standard flow rate of sample gas.
• Standard gas (type ZBM):
Reference gas used for calibrating zero
and span of the analyzer. When using a
zirconia oxygen meter, this is used together with air for calibrating zero for NO,
SO2, and CO and for calibrating span for
O 2.
• Zirconia O 2 sensor (type; ZFK4)
Used in combination with the infrared
analyzer. Outputs about 0V at measurement of the air, and an inverse logarithm
of about 1V at measurement of 0.05% O 2.
