Introduction Fuji Electric’s NDIR (Non-Dispersion Infrared Ray) gas analyzers have been widely used in many applications. The dual beam infrared gas analyzer models ZRF & ZRG can be incorporated with a zirconia oxygen sensor to measure oxygen. And with an internal microprocessor increases functionality, improves operationally and easy maintenance. And single beam infrared gas analyzer model ZRH which has simple structure, economical and easy maintenance has added joy to the family.
Contents Why use infrared analyzer for emission monitoring? What’s unique about Fuji’s gas analyzer? How reliable is Fuji’s gas analyzer?
I) Why use infrared analyzer for emission monitoring? Total production of SO2 & NOx analyzers in Japan in 1997 that is approved by JQA are 917 sets. JQA: Japanese Quality Assurance Organization NDIR: Non-Dispersion Infrared CLD: Chemi-Luminescence Detector UV: Ultra-Violet
I) Why use infrared analyzer for emission monitoring? • Both SO2 and NOx can be measured • Easy maintenance • Most cost effective • CLD : • Expensive • Difficult maintenance • UV: • Expensive • Short life (Light source approximately 6 months)
II) What is unique about Fuji’s gas analyzers? Various product’s line-up ZRH CO, CO2, CH4 & SO2 Simple Structure & Minimum Maintenance ZRF CO, CO2, NOx, SO2 & CH4 (+ O2) High Performance & 19” Rack Mounting ZRG CO, CO2, NOx, SO2 & CH4 (+ O2) High Performance & Wide Range, (CO: 0-2ppm) ZFP9 CO2 Controller Simple Air Monitoring
II) What is unique about Fuji’s gas analyzers? NDIR= Non-Dispersion Infrared Ray Gases have different kind of infrared absorption and by utilizing the wavelength corresponds to the waveband, we are able to determine the amount infrared ray being absorbed by the gases and we are able to tell the concentration. Internal pressure in the left detector will be higher than one in the right detector. And by blocking the ray, the pressure in both detectors will be equalized the changing volume of absorbing infrared ray is detected.
II) What is unique about Fuji’s gas analyzers? 1) Mass Flow Sensor Offers Excellent Linearity: ±1% FS High Rangeability: 20 to 1 Against Condenser Microphone (10 to 1) Less Effect By Vibration No Moving Mechanical Parts
II) What is unique about Fuji’s gas analyzers? 2) Single light source provides:- Long Term Stability : ±0.5% to 2% FS/week (Other suppliers show the stability for one day only) Against dual light source → Both sources cannot be exactly same → It creates error in measurement • Our test data of span drift for 28 days: Less than 1%FS (97.1ppm SO2/N2)
II) What is unique about Fuji’s gas analyzers? Butterfly wing sector 3) Single Point Chopper with Fuji’s peculiar rotary sector provides • Repeatability : ±0.2 to 0.5% FS because of excellent S/N ratio against conventional double point chopper
II) What is unique about Fuji’s gas analyzers? 4) Interference Compensating Detector Eliminates • Interference of Moisture Cross sensitivity to moisture : Less than 2 ppm at 2℃ of saturated H2O → Twin detector (Main detector + IC Detector) result in excellent compensation. • Interference of moisture & CO2 for NO measurement
II) What is unique about Fuji’s gas analyzers? 5) Wide Measuring Range → Minimum~Maximum Range CO : 0-50 ppm~100% (0-2 to 10ppm By Sample Switching Type) CO2 : 0-5 ppm~100% NO : 0-20 ppm~4000 ppm SO2 : 0-50 ppm~10% CH4 : 0-200 ppm~100%
21- On 21 - Os II) What is unique about Fuji’s gas analyzers? 6) Various Functions Standard 1) Self Diagnostic 2) Holding Output Optional Functions 1) Automatic Calibration in hour, day or week 2) Alarm Output 3) Remote Range Change 4) O2 Correction = x NOx or SO2 or CO 5) Average Value Output (In 1 or 4 hours)
III) How reliable is Fuji’s gas analyzers? 1) Long experience since 1952 10,000 installations as system 2) Many references for different industries Iron & Steel (700 sets), Incinerator (4,000 sets), Power Station (3,000 sets) & Others. 3) Accepted by major consultants & EPC • MHI ・Chiyoda • KHI ・JGC • IHI ・Toyo Engineering • SHI ・Ebara • Mitsui Ship Building
III) How reliable is Fuji’s gas analyzers? 4) Approved OEM suppliers with brand of • YOKOGAWA ELECTRIC (Japan) More than 200 sets per annum • CALIFORNIA ANALYTICAL INSTRUMENTS (USA) More than 200 sets per annum • SIGNAL (U.K.) More than 20 sets per annum • SIEMENS (Holland) More than 300 sets per annum
