  • Page 2: Preface

    PREFACE We thank you very much for purchasing Fuji Electric’s cross-stack laser gas analyzer (Type: ZSS). • First read this instruction manual carefully until an adequate understanding is acquired. Then proceed to installation, operation and maintenance of the laser gas analyzer. Improper handling may result in an accident or a failure.

  • Page 3: Caution On Safety

    CAUTION ON SAFETY First of all, read this “Caution on safety” carefully, and then use the particle counter in the correct way. The following items are important for safe operation and must be fully observed. These safety precautions are ranked in 2 levels; “DANGER” and “CAUTION.” ANGER If operation is incorrect, a dangerous situation may occur, resulting in death or serious injury.
  • Page 4 Caution on Wiring AUTION • Be sure to connect a ground wire securely to the specified place by per- forming class D grounding work. Otherwise electric shock or malfunction may result. • If the power supply voltage exceeds the rating, electric shock or damage to the instrument may result.
  • Page 5 Caution on operation and use ANGER • When handling the standard gas such as calibration gas, read the instruc- tion manual of the standard gas carefully, and use the gas correctly. • When toxic fumes, corrosive gas or inert gas is used as calibration gas, be sure that the position of the air ventilation or exhaust port is suitable.
  • Page 6 AUTION • If the cause of any fault cannot be determined despite reference to the in- struction manual, be sure to contact your dealer or Fuji Electric’s techni- cian in charge of adjustment. If the instrument is disassembled carelessly, you may get an electric shock or injury.

  • Page 11: General

    1. GENERAL 1.1 General Cross-stack laser gas analyzer (ZSS) provides continuous measurement of HCl in-flue gas incineration and density of denitration equipment 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 in- jection volume of calcium hydroxide is controlled while measuring HCl concentration.
