Notes:1. The lower and upper limits of the measuring range shown in the above table are for a measuring path length of 1 meter. See the “calculation method” below for other path lengths.2. Consult us for the ranges below 50 ppm.

Calculation method of measuring range for optical path lengths other than 1mMeasuring range = [Lower/upper limit ÷ path length]

Example. 1) HCl analyzer, path length 5m Upper limit: 5,000ppm ÷ 5m = 1,000ppm Lower limit: 10ppm ÷ 5m = 2ppm Therefore, measuring range is between 0 to 2 ···1,000ppm

Example. 2) HCl analyzer, path length 0.5m Upper limit: 5,000ppm ÷ 0.5m = 10,000ppm Lower limit: 10ppm ÷ 0.5m = 20ppm Therefore, measuring range is between 0 to 20 ···10,000ppm

Apr. 4, 2017

Cross stack laser gas analyzer (ZSS) provides continuous measurement of HCl contained in fl ue gas in waste incin-eration plants and industrial waste disposal facilities, NH3 in power plants and denitration equipment, CO, CO2, and O2 in iron and steel plants and chemical plants with high speed response. Because ZSS is installed directly on the stack or the pipe through which the target gas passes, sample gas conditioning is not required. Being highly tolerant to dust, ZSS can be installed on the upstream of a bug fi lter where the gas sampling is usually diffi cult. ZSS is the fi rst laser gas analyzer in Japan that is designed for environmental moni-toring and process monitoring.

FEATURES 1. Low maintenance2. Low operating-cost: with no gas-sampling device and few

parts to be replaced3. Superior long-term stability 4. Hardly affected by cross interference from other gases

5. Fast response within 2 seconds6. Tolerant to high temperature and high dust7. Environment friendly: 75 VA, low power consumption

3. Consult us for the ranges above 400°C.4. Consult us if you select the O2 (air purge) version or the

H2O measuring version.5. Consult us for the ranges below 10 vol%.

Purge gas flow rate:Purge line is required for each of the transmitter side and the receiver sideMinimum flow rate (L/min) for 10k50A flange:

Flue gas flow velocity (m/s) × 10 L/min, or 20 L/min Note that required flow rate varies with operating envi-ronment.

FUNCTIONS CONTACT OUTPUTLow light transmission:

Contact is closed when the amount of the light received by the receiver unit is insufficient.

Out of range:Contact is closed when the measured value is outside the range.

Device failure:Contact is closed when the laser is failed, the laser tem-perature control is failed, the received light is excessive, and/or a communication error occurred.

During hold / during calibration:Contact is closed during calibration and during the analog output hold. The analog output is held at the preceding value or at the user-specified value.

Power interruption:Contact is closed when the power supply is interrupted.

CONTACT INPUT (OPTION)Average reset:

By applying rectangular-wave voltage (with a minimum pulse width of two seconds) to the average value resetting input terminal, a user can reset the O2-corrected average value to the initial value. By opening the contact, a user can re-start the output.

Switchover between the instantaneous value and the moving average value:

By applying rectangular-wave voltage (with a minimum pulse width of two seconds) to the instantaneous and moving average switching input terminal, a user can switch the analog output between the instantaneous value and the moving average value.

Output hold:By applying rectangular-wave voltage (with a minimum pulse width of two seconds) to the AO holding signal input terminal, a user can remotely hold the analog input. Apply-ing the voltage again allows him/her to release the hold.

OTHER FUNCTIONSO2 correction:

PERFORMANCE at 1 atm and 25°C, except for H2O measurementRepeatability:

±1.0% FS (depends on gas, range, optical path length)Linearity:

±1.0% FS (depends on gas, range, optical path length)Zero point drift:

±2.0% FS per 6 months (depends on gas, range, optical path length)

Span drift:±3.0% FS per 6 months (depends on gas, range, optical path length)

Response time (T90):Approx. 1 to 2 seconds

Cross interference:≤ ±2% FSNotes:

1. The amount of some gases (e.g. HCl, NH3) adsorbed by water or other substances are not counted.

2. H2O measurement is a function to detect the pres-ence of moisture and its change. Note that its measurement accuracy is not guaranteed.

3. There may be some difference in measured concen-tration between the laser gas analyzer and manual analysis or other kinds of gas analyzers, because some degree of compensation error is generated depending on measuring environment (moisture concentration, pressure broadening, temperature, pressure, and/or purge gas flow rate).

4. Indication adjustment with manual analysis or other gas analyzers is provided with charge, only when requested.

Warm-up time:≤ 90 min

Minimum detectable limit:1% of range

GAS CONDITIONSTemperature:

See Table1 on page 1, “Measurable components and range limits”.*For measurement of high temperature gas of 500°C or above, install a pressure sensor on the purge line to moni-tor the purging status. If the purge is suspended under the high temperature gas environment, the product may be seriously damaged.

Pressure:±10 kPa (Consult us if the gas pressure exceeds this limit.)

Dust (when the optical path length is 1 m):≤ 5 g/m3 (N) Dust resistant version (22th code H): ≤ 15 g/m3 (N)O2 measurement: ≤ 10 g/m3 (N)Low level CO: 20 g/m3 (N)Consult us if your application has high dust. Dust resis-tance varies with the target gases, specification, optical path length, particle size of dust, and other conditions.

Flow velocity:Depends on the amount of the purge gasFor 50A pipe:Flow velocity (m/s) ≈ purge flow rate (L/min) of each purge line / 10

Moisture:≤ 50 vol%, or not saturated (no condensation)*Measurement may be unavailable when the gas contains

25 vol% or more moisture, the concentration of a target gas component is low, and the component has a tendency to be adsorbed by water.

CALIBRATIONCycle:

Every 6 months*the cycle may change according to the operating en-vironment.

Method:Remove the transmitter and the receiver from the stack, attach them to the calibration cells, and flow the standard gas with a flow rate of 1.5 to 2.0 L/min. (calibration cells and standard gas are to be prepared separately)

(when the calibration cell is 1 m)

BASIC PRINCIPLEZSS uses the near-infrared semiconductor laser as the light source, and photo-diode as photodetector. Each gas component has its own wavelength range where it absorbs the light, and a wavelength range consists of a set of many absorption lines, as shown in the figures below. As ZSS can aim at only one absorption-line among them, the measurement principally receives no interference from other gases. ZSS also focus on the amplitude of modulated signal, instead of the amount of change in light intensity, to detect gas concentration.

Notes:• For O2 analyzers other than the instrument air purge version, use N2. For all the other cases, use instrument air. If you use air that contains oil and/or mist, the purge gas flow decreases due to the contaminant, which adversely affect the measurement. In such a case, frequent maintenance is required, and in some cases you may have to install a filter additionally. • Once you install the analyzer, you have to purge the equipment with instrument air or N2 regardless if the analyzer and the furnace are in operation or not. If you operate the furnace without purging, it may cause the fatal damage to the optical part.

*1: When the flue gas contains a large amount of dust, ensure the minimum length of 50 mm.*2: When the flue gas temperature is high (500°C or more), ensure the minimum distance of 400 mm. Note that in that case you have to be even more careful in adjusting the angle of the companion flange because the angle range within which the companion flange can be adjusted is narrow.*3: Make sure to install the analyzer in the place where it is easy to operate, and where there is enough clearance.*4: Scaffold is required for both the receiver unit side and the transmitter unit side.*5: Use a flanged valve where there is a risk of gas blowout or where the operator may be exposed to a dangerous situation.*6: Tightening torque for the companion flange shall be 118±14 N·m. When tightening the bolts of the flange or the angle adjustment unit, apply grease to the bolts. (Recommended grease is the one contains molybdenum.)

Keep purging the analyzer once you install it on a stack. Otherwise, the contamination of optical surface may result in the analyzer failure.
