General; Handling Of Product And Operating Precautions - Fuji Electric FE ZSS Instruction Manual

Cross-stack laser gas analyzer (ZSS) provides continuous measurement of HCl in-flue gas incineration and
NH density of denitration equipment within a short response time. The cross-stack configuration eliminates
3
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 in-
jection volume of calcium hydroxide is controlled while measuring HCl concentration.
The analyzer adopts near-infrared laser as light source. The measuring object of the analyzer is only one
spectrum line from large numbers of absorption spectrum lines, and it measures concentration by controlling
temperature and power current. Since the range of wavelengths to be measured is a few nano meters, the ana-
lyzer has 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 Handling of product and operating precautions

First read this instruction manual carefully, and then make a plan for periodic inspection to perform appro-
priate maintenance management. To maintain the long-term performance of the cross-stack laser gas analyzer
(ZSS), our periodic inspection contract is recommended.
This analyzer uses the invisible infrared laser. Do not watch the laser beam directly (with an optical measur-
ing device included) or scattering light.
