1. OVERVIEW

This infrared gas analyzer (type: ZKJ) measures the concentration of NO, SO

2

, CO

2

, CO and CH

4 contained in sampling gas on the principle that different atomic molecules have an absorption spectrum in the wave band of infrared rays, and the intensity of absorption is determined by the Lambert-Beer law.

Since this instrument incorporates a compact paramagnetic O

2

sensor, it allows measuring up to 5 components simultaneously by using the built-in O

2

sensor (up to 4 components if O

2

sensor is excluded).

Furthermore, use of a microprocessor or large sized liquid crystal display realizes improvement of operability, accuracy and multi-functions.

This instrument is optimum for measuring combustible gas exhausted from boilers or incinerators, and it is effective for steel gas analysis (blast furnace, steel converter, thermal treatment furnace, sintering

(Pellet equipment), coke furnace), storage and maturity of vegetable and fruit, biochemistry (microbe),

[fermentation], air pollution [incinerator, exhaust gas desulfurization, denitration], automotive emission

(excluding tester), protection against disasters [detection of explosive gas and toxic gas, combustion gas analysis of new building material], growth of plants, chemical analysis [petroleum refinery plant, petroleum chemistry plant, gas generation plant], environment [landing concentration, tunnel concentration, parking lot, building management] and various physical and chemical experiments.

3.4 Sampling

3.4.1 Conditions of sampling gas

(1) Dust contained in the sampling gas should be completely removed with a filter. For the final stage filter, use a filter that allows removing dust particles of 0.3

µm.

(2) Dew point of sampling gas must be lower than the ambient temperature to avoid occurrence of drain in the gas analyzer. If vapor is contained in the sampling gas, dew point should be lowered to 0˚C by using a dehumidifier.

(3) If SO

3

mist is contained in the sampling gas, use a mist filter or cooler to remove SO

3 mist.

Other mists should be removed by using a mist filter or cooler.

(4) Corrosive gases such as Cl

2

, F

2

and HCl, if they are contained in the sampling gas in considerable amounts, will shorten the life of instruments.

(5) Temperature of sampling gas should be within 0 to 50˚C. Provide a means that prevents entry of hot gas directly into the instrument.

3.4.2 Sampling gas flow

Flow of sampling gas should be 0.5L/min

± 0.2L/min.

Avoid flow fluctuation during measurement.

Observe the flow reading by a flowmeter provided as shown in the example of the sampling system configuration (Item 3.4.6).

3.4.3 Preparation of standard gas

Routine calibration is required by standard gas for keeping this instrument under normal operation condition (once a week). Prepare a standard gas cylinder for zero calibration and span calibration.

3.4.4 Purging of instrument inside

The inside of instrument need not be purged generally except for the following cases.

(1) A combustible gas component is contained in sample gas.

(2) Corrosive gas is contained in the atmospheric air at the installation site.

(3) The same gas as the sample gas component is contained in the atmospheric air at the installation site.

In such cases as above, the inside of analyzer should be purged with the air for instrumentation or N

2

.

Purging flow rate should be about 1L/min.

If dust or mist is contained in purging gas, it should be eliminated completely in advance.

• Avoid installing this instrument near an electrical unit (high frequency furnace or electric welder) that generates much electrical noise. If using the instrument near such a noise generating unit is unavoidable, use a different power line to avoid noise.

Main unit power supply

Varistor or spark killer

• Mount a noise suppressor such as varister or spark killer as shown at right figure to the noise generating unit when noise is generated from relays or solenoid valves.

Mount the suppressor near the noise generating source, or it will have no effect.

Install (connect) near the source.

[% full scale] represents the percentage with the CO range regarded as 100%.

Action of peak alarm

Example

If CO concentration exceeds the alarm value, counting will begin. If the number of peaks is over the set times per hour, a peak alarm contact output becomes closed (ON). If it is less than the set times per hour, it is open (OFF). Since 5 times of peaks /hour is marked at (1) section from the above graph, the peak count alarm is turned ON. Since peaks of more than 5 times per 1 hour occur at the interval between (1) and (2) , the peak count alarm remains ON. Since at (2), peaks are reduced to 4 times per hour, it is turned OFF.

Like the hysteresis of the alarm setting , the hysteresis prevents possible chattering when measured gas is fluctuated near the alarm value.

* For 10 minutes after the power is turned ON, a peak alarm counting is not carried out.

Releasing peak count alarm

To release the peak count alarm, set the peak alarm to OFF.

Turning on the peak alarm initiates counting from 0.

7.3.2 Cleaning method for sample cell (block cell)

(1) Turn off the power switch, stop the sample gas, and allow the zero gas to flow for several minutes to purge the cell interior.

Loosen the setscrew (2 pieces) from the top cover and remove it.

(2) Remove the internal gas inlet tube.

(3) Loosen the 2 detector set bolts.

Note) The distribution cell, block cell and detector are fastened by the same bolts.

(4) Using the furnished cell mounting tool, turn the window fixture to the left and remove it from the cell.

(See the structure of sample cell (block cell) in Fig. 7-2.)

(5) For cleaning the infrared transmission window and cell inside surface, first eliminate coarse dust by soft brush or the like and then wipe them by soft rag.

The window is easy to get scratched.

Pay utmost attention so as not to damage it.

(6) After the end of sample cell cleaning, mount the cell in place and proceed to running.

After cleaning sample cell, be sure to perform optical zero adjustment (see

Item 7.3.3) and moisture interference compensation adjustment (see Item

7.3.4).

2. Standard Functions

Output signal holding:

Output signals are held during manual and auto calibrations by activation of holding

(turning “ON” its setting).

The values to be held are the ones just before start calibration mode or setting value.

It is selectable.

Indication of instantaneous values will not be held.

Remote output holding:

Output signal is held at the latest value or setting value by short-circuiting the remote output holding input terminals.

Holding is maintained while the terminals are short-circuited. Indication of instantaneous values will not be held.

Switch ranges:

The switch ranges is available in manual, auto, and remote modes. Only preset switch method is effective.

Manual: Allows range to switch by key operation.

Auto: Allows range to switch from low to high range when 90%FS or more is available in the low range.

Allows range to switch from high to low range when 80%FS or less is available in the low range.

Remote: No-voltage contact input (for measurable components)

Allows range to switch via an external signal when remote range switch input is received.

When the contact input terminals for each component are short-circuited, the first range is selected, and it is switched to the second range when the terminals are open.

Range identification signal:

The present measuring range is identified by a contact signal.

The contact output terminals for each component are short-circuited when the first range is selected, and when the second range is selected, the terminals are open.

Auto calibration:

Auto calibration is carried out periodically at the preset cycle.

When a standard gas cylinder for calibration and a solenoid valve for opening/closing the gas flow line are prepared externally by the customer, calibration will be carried out with the solenoid valve drive contacts for zero calibration and each span calibration turned on/off sequentially at the set auto calibration timing.

Auto calibration cycle setting:

Auto calibration cycle is set.

Setting is variable within 1 to 99 hours (in increments of 1 hour) or 1 to 40 days (in increments of 1 day).

Gas flow time setting:

The time for flowing each calibration gas in auto calibration is set.

Settable within 60 to 900 seconds (in increments of 1 second)

Auto calibration remote start:

Auto calibration is carried out only once according to an external input signal.

Calibration sequence is settable in the same way as the general auto calibration.

Auto calibration is started by opening the auto calibration remote start input terminals after short-circuiting for 1.5 seconds or longer.

Auto zero calibration:

Auto zero calibration is carried out periodically at the preset cycle.

This cycle is independent on “Auto calibradion” cycle.

When zero calibration gas and solenoid valve for opening/closing the calibration gas flow line are prepared externally by the customer, zero calibration will be carried out with the solenoid valve drive contact for zero calibration turned on/off at the set auto zero calibration timing.

Auto zero calibration cycle setting:

Auto zero calibration cycle is set.

Setting is variable within 1 to 99 hours (in increments of 1 hour) or Setting is variable within 1 to 40 days (in increments of 1 day)

Gas flow time setting:

The timing for flowing zero gas in auto zero calibration is set.

Settable 60 to 900 seconds (in increments of 1 second)

Upper/lower limit alarm:

Alarm contact output turns on when measurement value reach to the preset high or low limit alarm value.

Contacts close when the channel value of each channel becomes larger than the high alarm limit value or smaller than the low alarm limit value.

Instrument error contact output:

Contacts close at occurrence of analyzer error No. 1, 3 or 10.

Calibration error contact output:

Contacts close at occurrence of manual or auto calibration error (any of errors No. 4 to 9).

Auto calibration status contact outputs:

Contacts close during auto calibration.

Pump ON/OFF contact output:

During measurement, this contact close.

While calibration gas is flowing, this contact open. This contact is connected in power supply of pump, and stop the sample gas while calibration gas flowing.

Within 60 seconds including replacement time of sampling gas

(when gas flow rate is 0.5L/min)

Gas replacement time depends on the number of measuring components,and measuring range calculation:

The result of O2 conversion or instantaneous O2 value can be outputted as an average value in the preset period of time.

Used for averaging is the moving average method in which sampling is carried out at intervals of 30 seconds.

(Output is updated every 30 seconds. It is the average value in the determined period of time just before the latest updating.)

Averaging time is settable within 1 to 59 minutes (in increments of 1 minute) or 1 to 4 hours (in increments of 1 hour).

Average value resetting:

The above-mentioned output of average value is started from the initial state by opening the average value resetting input terminals after short-circuiting for 1.5 seconds or longer.

Output is reset by short-circuiting and restarted by opening

CO concentration peak count alarm:

(added only for CO/O2 measurement)

Alarm output turns on according to the preset concentration and count.

Whenever the instantaneous value of CO exceeds the preset concentration value, count increments. If the count exceeds the preset value in one hour, the alarm contacts close.

Note 1 a) When “B” is specified at the 6th digit, O

2

sensor signal has to be set as 0-1V DC linear corresponding to full scale.

b) External Zirconia O

2

sensor and external O

2

analyzer are not included in the scope of supply, and has to be separately

ordered.

Note 2 a) When “H”, “L” and “M" with purging are specified at 5th digit, only one set of gas inlet/outlet is provided.

In this case, NO

2

/NO converter cannot be mounted in between of two measuring cells.

b) Resin coupling with purging cannot be manufactued.

Note 3 Rated voltage and plug type of the attached power cable is different depending on the code “J”, “E” and “U” in the 10th digit.

Select appropriate code according to operationg power supply voltage in the final destination.

Note 4 Measuring range can be selected within either the minimum or maximum range.

(Within min. or max. range, you can change the actual range settings locally.)

Initial setting from Fuji factory is Min. range for the 1st range, and Max. range for the 2nd range.

When range preset at Fuji factory is required, please select “specified range” at 23rd digit and inform Fuji of specified range table.

Refer to Table 1, for possible combination of measuring components and ranges in the data sheet.

Note 5 “1E” can be specified at 11th & 12th digits, ONLY for CO

2

measurement.

In this case, be sure to select “with purging” at 7th digit.

Note 6 O

2

conversion is calculated only for NO, SO

2

and CO.

Both average value output after O

2

calculation and O

2

average value output are provided at the same time.

a) Peak count alarm can be added only for CO measurement.

Note 7 When “Y” is specified at the 6th digit, 22nd digit always has to be specified as “Y”.

Note 8 a) If you would like Fuji to deliver ZKJ analyzer with specific range setting, select “specified range” and separately inform

Fuji of the actual range of each component together with your purchase order.

b) In case that the measurement unit is specified as “mg/m3”, it is necessary to select “unit : mg/m 3 ” (Code “F” or “G”)

at the 23rd digit.

Please refer to the table shown below for the corresponding range code based on “mg/m 3 ”.
