Fuji Electric ZSS Straight-Inserted Laser Gas Analyzer Product Specifications (English)

CROSS St ACK LASe R GAS An ALYZe R

DATA SHEET ZSS Cross stack laser gas analyzer (ZSS) provides continuous measurement of density of HCl contained in fl ue gas in waste incineration plant and industrial waste disposal facility, NH3 in power plant and denitration equipment, CO, CO2, and O2 in iron and steel plant and chemical plant with high speed response. Since ZSS is installed directly on the fl ue(pipe)

Control unit

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 dif-

(Range in the case stack (optical path length) diameter is 1m) Max. and min. ranges for each stack diameter = (Max. and min. ranges when stack diameter is 1m) ÷ Stack diameter * Stack diameter = Optical path length (Example: In case stack diameter is 2m for HCl measurement, Max.range: 2500ppm and min. range: 5ppm).
