  • Page 5: Introduction

    General Information Introduction Overview The Model 9700 analyzer system (see Figure 1) is an integrally housed combination of analyzers designed to continuously monitor the two primary components of flue gas which are the best indicators of combus- tion efficiency and safe operation. Through use of volumetric percentage...

    T-joint where a spray nozzle introduces a fine water mist. This mist cools and wets the sample. A strainer is built into the system to prevent the nozzle from being clogged by particulates in the cooling water.

  • Page 8: Oxygen Analyzer Section

    General Information Model 9700 Oxygen Analyzer Section The analysis system (see Figure 3) employs a Model 326B Analyzer which features a TBE/AI unique, patented Micro-Fuel Cell oxygen sensor. This electrochemical transducer provides an electrical signal that is directly proportional (and specific) to the oxygen concentration in the gas phase immediately adjacent to its sensing surface.
  • Page 9 To eliminate the inaccuracies caused by varying temperature conditions that are inherent in most methods of analysis em- ploying transducers, a system composed of a combination of temperature compensation and control is used in the analyzer. TELEDYNE BROWN ENGINEERING Analytical Instruments...
  • Page 10 General Information Model 9700 To protect the Micro-Fuel Cell against damage from low ambient temperatures and reduce the range required of the compensation circuit, the analyzer is equipped with a thermostatically controlled heating system that will not permit the interior of the instrument to drop below 85 deg F.
  • Page 11: Optional Features

    The relays are arranged to be in an energized condition when the oxygen concentration of the sample is in the safe region of the scale. The form “C” SPDT relay contacts are rated at 3 amperes (non-inductive). TELEDYNE BROWN ENGINEERING Analytical Instruments...
  • Page 12 General Information Model 9700 • E-to-I Converter A voltage (E) to current (I) conversion of the output signal generated by the analyzer is available. This conversion allows I (current) to P (pneumatic) devices, as well as low-impedance current-operated indicating and/or recording and controlling instruments to be directly driven without the need of accessory equipment.

    2 Theory of Operation Model 9700 An optional CAUTION alarm circuit utilizes potentiometer P4 to establish the setpoint. When the setting of P4 is exceeded. transistor Q2 is turned on and relay K1 is energized, resulting in an alarm. The optional FAILURE alarm circuit is set up so that if the detector opens up, an alarm comparator will trip and turn off a relay, which is normally energized, i.e., during the non-alarm condition, the normally...

    4 Operation Model 9700 The Micro-Fuel Cell is supplied separately in a controlled atmosphere package and must be installed prior to startup. To install the cell, use the following procedure: Note: Do not open the sealed package until the system is to be started and a flue gas sample is available .
  • Page 31 Note: It is particularly vital to the condition of the A-3 cell employed in flue gas (or high CO content applications) that the cell not be exposed to a CO free environment for a prolonged period of time. TELEDYNE BROWN ENGINEERING Analytical Instruments...
