CRoss stack LAseR GAs AnALYZeR

Ross stk LseR Gs nlyzer DT SHEET ross stack laser gas analyzer (ZSS) provides continuous measurement of density of Hl contained in fl ue gas in waste incineration plant and industrial waste disposal facility, NH3 in power plant and denitration equipment, O, O2, and O2 in iron and steel plant and chemical plant with high speed response. Since ZSS is installed directly on the fl ue(pipe) where objective gas fl ow to be measured, preparation is not required for measured gas to be introduced to the analyzer, which is required for sampling method. This analyzer can be used under high dust conditions, so it is possible to install upstream of the bagfi lter where gas sampling is normally diffi cult. This is the fi rst laser gas analyzer for environment and process in Japan produced by Fuji. Receiver unit ontrol unit ZSS FetuRes. Maintenance free thanks to using the long-term stable parts. 2. Running cost is minimized by no need of gas sampling devices and having few parts to replace. 3. Long and high stability due to almost no drift. 4. Since adopting the near-infrared semiconductor laser which emit light of the wavelength of measured component, hardly affected by interference of other gas.. It is suitable for injection control of slaked lime, measuring the residual ammonia gas and monitoring and control of converter furnace of combustible gas recovery due to high-speed response for to seconds.(high-speed response type: to 2 seconds) 6. It is measurable at high temperature and dust circumstance. In addition performance of dust resistance has been improved. 7. It is environment-friendly product. ecause power consumption is V or lower when V. speifitions Measurement principle: Non-dispersive infrared absorbance system (NDIR) Measuring method: ross-stack system (path system) use application: Waste incineration plant, industrial waste disposal facility, power plant iron and steel plant, paper plant, pulp mill, chemical plant and bioplant etc Light source: Near-infrared laser Laser class: lass (excluding some of O2 meters) outline (D W H) mm: Receiver unit (8 x approx.4 x approx.mm) Transmitter unit (24 x approx.4(432) x approx.6mm) ontrol unit (37 x2 x 44mm) Transmitter unit Mass: Receiver/Transmitter unit: pprox. kg ontrol unit: pprox. 8kg structure: Outdoor use type, dustproofi ng/rainproofi ng structure (IP6) ox finish color: Receiver/Transmitter box: gray ontrol unit cover: blue ontrol unit case: silver Measurable component and range: omponent Min. measuring Max. measuring range range Hl ppm ppm Hl+H2O (*) ppm (Hl) ppm (Hl) NH3 ppm ppm NH3+H2O (*) ppm (NH3) ppm (NH3) O2 (low output type) 4 vol% vol% O2 (For use in high dust) 4 vol% vol% O2 (For combustion control) 2 vol% 2 vol% O 2. vol% vol% O (For use in high temperature) vol% vol% O2 2. vol% vol% O2 (For use in high temperature) vol% vol% O+O2 2. vol% vol% O+O2 (For use in high temperature) vol% vol% H4 ppm vol% (*) Range for H2O is fi xed at vol% m.
