1. DESCRIPTION
1.1 Introduction
Cross-stack laser gas analyzer (ZSS) provides continuous measurement of HCl in flue gas incineration, NH3
concentration of denitration equipment and heat treat furnace, and O2, CO, and CO2for combustion control
within a short response time. The cross-stack configuration eliminates 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 injection volume of calcium hydroxide is con-
trolled while measuring HCl concentration. The analyzer adopts near-infrared laser as light source. The ana-
lyzer targets only one spectrum line among a large number of absorption spectrum lines, and carry out a
measurement while controlling the temperature and the driving current of the laser. Since the range of wave-
lengths to be measured is as narrow as a few nanometers, the analyzer receives 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 Compliance
First read this instruction manual carefully, and then make a plan for periodic inspection to perform appro-
priate maintenance management.
This analyzer uses the invisible infrared laser (excluding O2analyzer). Do not watch the laser beam directly
or scattering light.
