CROSS STACK LASER GAS ANALYZER

Transcription

1 DATA SHEET CROSS STACK LASER GAS ANALYZER (Single beam version) ZSS-S Cross stack laser gas analyzer (ZSS) provides continuous measurement of HCl contained in fl ue gas in waste incineration 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 monitoring and process monitoring. Receiver unit Control unit FEATURES 1. Low maintenance 2. Low operating-cost: with no gas-sampling device and few parts to be replaced 3. Superior long-term stability 4. Hardly affected by cross interference from other gases Transmitter unit 5. Fast response within 2 seconds 6. Tolerant to high temperature and high dust 7. Environment friendly: 75 VA, low power consumption SPECIFICATIONS Table 1.

2 ZSS-S Measurement principle: Non-dispersive infrared (NDIR), cross-stack system Display contents: Gas components, concentration (instantaneous value, average value, O2 corrected instantaneous value, O2 corrected average value), alarm Light source: Semiconductor laser, Class 1 (O2 analyzer for hightemperature gas and O2 analyzer with instrument air purge use Class 3B laser) Analog output: 4 20 ma DC, 0 20 ma DC, 0 1 V DC, 0 5 V DC, or 1 5 V DC No-insulation, 2 or 4 points Allowable load: 4 20 ma DC, 0 20 ma DC: 550Ω 0 1 V DC: 100 kω 0 5 V DC, 1 5 V DC: 500 kω Analog input (for concentration compensation, O2 correction, and alarm output) 4 20 ma DC, 2 points or 6 points (as specified by model code) Input type (user can set the content for each channel among the followings): gas pressure, gas temperature, gas flow velocity, O2 concentration, H2O concentration, purge gas pressure Contact output: 1 from A (normally open) relay contact, 4 points (device failure, low light transmission, out of range, during hold/ during calibration) 1 from B (normally closed) relay contact, 1 point (power interruption) Contact capacity: 24 V DC, 1 A (resistive load) Contact input (option): Voltage input (12 24 V DC, 20 ma), 3 points (output hold, switchover between instantaneous value/average value, average reset) Between contacts and between each contact and the internal circuit are insulated by photo coupler. Power supply: Rated voltage: V AC Operating voltage: V AC Rated frequency: 50/60 Hz Power rating: 75 VA Purge: To remove dust and/or moisture from the transmitter unit and the receiver unit, and to decrease temperature inside the units *Purging equipment is available. See page 6. Purge gas: Instrument air that contains neither dust nor mist Use N2 for explosive gas or combustible gas, or for O2 measurement that cannot use instrument air purge Purge gas pressure: 0.3 Mpa (depends on flow rate, pipe diameter, and length of purge line) Purge gas flow rate: Purge line is required for each of the transmitter side and the receiver side Minimum 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 environment. Storage conditions: Ambient temperature: -20 C to +60 C Ambient humidity: 95% RH Dimensions: Receiver unit: approx mm Transmitter unit: approx mm Control unit: approx mm Weight: Control unit unit and receiver unit: approx. 10 kg each Transmitter: approx. 8 kg Cable length: Between transmitter unit and receiver unit: standard 2 m (Maximum 25 m) Between transmitter unit and receiver unit: standard 5 m (Maximum 100 m) Finish color: Transmitter box and receiver box: grey Control unit case: silver Control unit front cover: blue Enclosure: For outdoor installation, dust and rain proof (IP65) Transmitter unit and receiver unit: aluminum + stainless steel Control unit: aluminum Major materials of gas contacting parts: Stainless steel 316, BK7, PTFE, glass-cloth, silicone Purge gas port: Joint for 10/8 PTFE tube (Rc1/4 when the joint is removed) FUNCTIONS CONTACT OUTPUT Low 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 temperature 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. Applying the voltage again allows him/her to release the hold. OTHER FUNCTIONS O2 correction: Conversion of measured CO gas concentrations into values at reference O2 concentration Correction formula: 21 On C = Cs 21 Os C: Converted concentration Cs: Measured concentration of sample gas Os: Measured O2 concentration (Upper limit settable between 1 and 20%) On: Reference O2 concentration (changeable between 0 and 19%) The result of calculation is indicated and transmitted as an analog output signal. 2

3 Dry/wet value output: A user can switch the indication and the output between wet values (concentrations which include moisture) and dry values (concentration from which the moisture content is eliminated). The moisture concentration can be set by key or by the analog input. Communication interface: USB (for adjustment data loading) PERFORMANCE at 1 atm and 25 C, except for H2O measurement Repeatability: ±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% FS Notes: 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 presence of moisture and its change. Note that its measurement accuracy is not guaranteed. 3. There may be some difference in measured concentration 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 CONDITIONS Temperature: 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 monitor 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/m 3 (N) Dust resistant version (22th code H): 15 g/m 3 (N) O2 measurement: 10 g/m 3 (N) Low level CO: 20 g/m 3 (N) Consult us if your application has high dust. Dust resistance 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 gas For 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. CALIBRATION Cycle: Every 6 months *the cycle may change according to the operating environment. 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) Zero gas: Dry N2 Span gas: 80% to 100% concentration of each range, balance N2 (when the calibration cell is 1 m) INSTALLATION ENVIRONMENT Location: Where the transmitter unit and the receiver unit can be directly mounted across the stack Where the scaffolding for maintenance can be provided Where the transmitter unit and the receiver unit can be monitored without difficulty Where the transmitter unit, the receiver unit, and the control unit are not exposed to direct sunlight Vibration: 0.5 G ( 0.2 G for a frequency band from 20 Hz to 40 Hz) Ambient temperature (including the case temperature affected by radiant and/or conductive heat): Transmitter unit and receiver unit: -20 C to +55 C Control unit: -5 C to +45 C Ambient humidity: 90% RH Mounting angle: ±5 from the horizontal (No dew shall accumulate on the lenses of the transmitter unit and the receiver unit) Optical path length (stack inner diameter): 0.5 m to 10 m Mounting flange: JIS 10K 50A (standard), others (as specified) Purge Instrument air (if not available, a compressor is required. The air shall contain neither oil nor mist.) Use N2 for O2 analyzers other than the instrument air purge version. Purge gas pressure: 0.3 MPa (depends on the flow velocity of target gas) Calibration cycle: Every 6 months (the cycle may vary depending on the installation environment) EC DIRECTIVE COMPLIANCE Low voltage (LVD): EN : 2013 EN 62311: 2008 Installation category: II Electromagnetic Compatibility (EMC): EN 55011: 2009, A1: 2010 EN : 2006, +A1: 2009, +A2: 2009 EN : 2008 EN : 2013 EN : 2013 Measurement category: CAT II 3

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.

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. 8

11 MOUNTING DIMENSIONS (in mm) Keep purging the analyzer once you install it on a stack. Otherwise, the contamination of optical surface may result in the analyzer failure. Stack c d Angle adjustment unit (*6) a b (*6) Companion flange (*5, *6) e a: inside diameter 50 mm b: 20 to 70 mm (*1) c: approx. 200 mm (*2) d: 400 mm (*3) e: 500 to 1500 mm(*3) Scaffold (*4) *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.) ROUGH guide to mount the companion flange When θ is larger than 5, attach the companion flange with the γ angle 5 inside the circumference of radius A.
