1. DESCRIPTION

1.1 Introduction

Cross-stack laser gas analyzer (ZSS) provides continuous measurement of HCl in flue gas incineration, NH3 concentration of denitration equipment and heat treat furnace, and O within a short response time. The cross-stack configuration eliminates the need for transfer of the preparation measurement gas to the analyzer for proper measurement. Dust resistant construction enables installation upstream of bug filter units and the application for which injection volume of calcium hydroxide is controlled while measuring HCl concentration. The analyzer adopts near-infrared laser as light source. The analyzer targets only one spectrum line among a large number of absorption spectrum lines, and carry out a measurement while controlling the temperature and the driving current of the laser. Since the range of wavelengths to be measured is as narrow as a few nanometers, the analyzer receives minimum interference by other crossovers. For the concentration detection, the modulated intensity of signal amplitude is employed instead of the amount of change of light.

1.2 Compliance

, CO, and CO2 for combustion control

First read this instruction manual carefully, and then make a plan for periodic inspection to perform appropriate maintenance management. This analyzer uses the invisible infrared laser (excluding O

analyzer). Do not watch the laser beam directly

or scattering light.

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.)

4.3 Mounting range of companion flange

Mount the companion flange so that it satisfies the conditions of the following figure (Fig. 4－2). If the conditions below are not satisfied, light cannot be received even if the light axis adjustment is performed by the

angle adjustment unit. In such a case, mount the companion flange again.

When θ (angle determined by laser light source and flange diameter) is bigger than 5°, mount the companion flange within the angle γ (≤ 5°) inside the circle with radius A. When the distance between laser light source and stack is long, or θ angle is less than 5° because flange diameter is small, both radius A and angle γ will become smaller, and the mounting conditions will be strict.

4.7.1 How to use the angle adjustment unit 1

(1) When you tighten the flange B

Turn the fixing bolt and the anchor nut clockwise at the same time. If it is difficult to turn them, slightly loosen the anchor nut first. (approx. one-tenth rotation)

(2) When you loosen the flange B

Turn the fixing bolt and the anchor nut counter-clockwise at the same time. If it is difficult to turn them, slightly loosen the anchor nut first. (approx. one-tenth rotation)

(3) When you fix the flange B

When angle is determined after adjustment in 1) or 2), turn them in the direction opposite to each other to fasten them. Be careful because if the fixing bolt and the anchor nut are too far away from the flange B, the angle will slip.

Note) Pay attention to the insertion angle of the tool. Take utmost

care not to turn at the angle which may let the bellows contact

with the head of the spanner. Otherwise, the spanner may crush

the bellows.

4.11 Light intensity adjustment

Note that if you loosen multiple bolts and nuts at a time, it takes considerable time to re-adjust the angle.

4.11.1 When an optional optical axis adjusting tool (laser pointer) is used

(1) Connect the digital voltmeter using the BNC cable, referring to “4.6 Received light ”. (2) The reference light intensity is based on the output in zero calibration or voltage value of light intensity

which is described in a nameplate. If the output is not as much as that measured at the time of calibration before the adjustment, find a position where the received light intensity increases, moving the transmitter box from side to side and up and down slowly. (*1)(*2)(*3)

e.g.) In the case that the light intensity increases when the

whole transmitter box is moved upward.

As the light intensity increases when the light axis turns

→

downward, tighten the fixing bolt in reference to “4.7.2 How to use the angle adjustment unit 2”.

(3) If the output voltage is less than the value obtained during a zero calibration despite your adjustment of

the transmitter box to make the output maximum, fix the transmitter box and then move the receiver box to adjust the optical axis.

Do not loosen more than one bolt or loosen fixing bolt and nut widely in both cases of adjustment.

Light axis may deflect again.

(4) Retighten all volts to fix them (If the light intensity decreases at retightening, adjust again).

*1) Received light intensity might not increase to its maximum that was confirmed by “4.6 Received light ”

due to the influences from dust and moisture in the stack.

*2) When using the high-speed/AGC version (i.e. the 22th digit of code symbols is "H"), adjust the light axis

under the status that the level of AGC is "01" (refer to "5.3 Outline of screen ").

*3) When using CO + O

Page 34

4.11.2 When an optional optical axis adjusting tool (laser pointer) is not used

which is described in a nameplate. When the light intensity is completely zero V, move the transmitter box from side to side and up and down slowly to find the position where the received light intensity increases. If you cannot still confirm the light intensity, loosen the fixing bolts and nuts further, and check reaction of the digital voltmeter while moving the box back and forth slowly.

(3) If you find reaction of light intensity increases, fasten the fixing bolts and nuts temporally, and perform

the operation in 2). (*4)

(4) If output is not as much as that measured at the time of calibration even if output is at its maximum on

the transmitter side, fix the box at the maximum output angle temporality and adjust the light axis, moving the box on the receiver side similarly. When you can confirm the output at the time of adjusting any of the boxes, do not loosen the fixing bolts and nuts too much, or the light axis can deflect further. Do not loosen more than one bolt or loosen fixing bolt and nut widely in both cases of adjustment. Light axis may deflect again.

(5) Move the transmitter unit and the receiver unit from side to side and up and down to adjust until the

voltage value of light intensity of digital multimeter becomes smaller in all directions.

(6) Retighten all volts to fix them (If the light intensity decreases at retightening, adjust again).

*4) Received light intensity might not increase to its maximum that was confirmed by “4.6 Received light ”

due to the influences from dust and moisture in the stack.

4.12 How to use the bolt for angle fine adjustment (standard accessory)

This bolt is used for adjustment when the light path length in the stack is long and when the light intensity misses too much at the time of retightening in the procedure in “4.11 Light intensity adjustment”. When each retightening is finished, perform fine adjustment by pressing with this bolt. When you use the fine adjustment screw, set it to the flange A before mounting the receiver and the transmitter boxes on the angle adjustment unit. The fine adjustment screw cannot be set after mounting these boxes.

4.13 Connecting to control unit

Do not supply the power until all the wiring work is completed. To ensure the watertight property of the cable glands, use the cables that have an outer diameter from 6 mm to 10 mm.

4.13.1 AC power connection

AC power connecting terminal is positioned at the lower left of the control unit (see Fig. 4－15.). Use the AC cable that has a flame resistance of 600 V, a cross-sectional area of 1.25 mm

(AWG16) or more, and an

outer diameter between 6 mm through 10 mm. Connect the grounding wire to the protective earth terminal.

When connecting the AC cable to the input terminal, the ground cable should be longer than the L, N line. The cable length should be adjusted so that when the AC cable is pulled from the external, the L, N line will be removed from the terminal block first, and the ground cable will be removed last. Add a ferrite core both inside and outside of the case. If you install the control unit outside, we recommend taking a measure to protect the ferrite core attached outside the case from deterioration; for example, cover it with plastic tape.

When noise source is in the vicinity

Avoid installing this analyzer near an electrical apparatus which produces power source noise. (Such as high frequency furnace, electric welder, etc.) If the analyzer must be used near such equipment, a separate power line should be used for avoiding noise. In case noise may enter from a relay, solenoid valve, etc. through power supply, connect a varistor (e.g. ENA211 OKAYA) to the noise source as shown in Fig. 4－16. If the varistor is located away

from the noise source, no effect is obtainable.

Fig. 4－16

CAUTION

• For power line, use the cables that have a cross-sectional area of 1.25 mm2 or more.

• Connect the power cable to the socket with the ground slot (class D grounding). For grounding line, use the cable that has a cross-sectional area of 2 mm

or more.

• For signal lines, use a shielded wire in order to suppress the influences by noise.

• For the digital contacts and the digital input lines, use cables that have a cross-sectional area of 0.12

(AWG26) or more.

• After the AC power cable is connected, put a power terminal cover on.

• Do not install the instrument near objects which considerably disturb power waveforms. Do not share their power supplies either. Otherwise, it may cause a display error.

• Power supply and output signal lines should be separated from each other.

• Use M4 solderless terminals for terminal connection.

• For the power line and the grounding line, use solderless terminals of the type that core wires and shield lines are crimped separately.

4.13.2 Connecting analog input/output

Connect the analog input and output properly, referring to “3.2 Wiring diagram”. According to your order, 4– 20 mA DC or 1–5 V DC analog signal is emitted. For connection of the signal cable, use an insulated converter (WS2DC Series, manufactured by Fuji Electric Technica Co., Ltd. or equivalent) to supress the influences by noise. Analog input signal shall be 4 to 20mA DC.

Note) If you connect the analog input to the analog output terminal, the printed circuit board may be dam-

aged. Check the terminal before connecting them.

4.13.3 Connecting digital input/output

Connect the contact input and output properly, referring to “3.2 Wiring diagram”. If it is provided with the separately submitted approved drawing, connect the contact input/output as shown in the drawing. For wiring, use shielded wires of which cross-sectional area are 0.12 mm
