Page 5: Introduction
Purpose of the analyzer The continuous COSA 9610™ analyzer determines online the Wobbe-index of a gas. The COSA 9610™ can be used both, as feed forward and feedback analyzer for gases mixing or as a feed forward analyzer for burning control. -
Page 6: Oven With Oxygen Sensor
INSTALLATION, OPERATION AND MAINTENANCE MANUAL – COSA 9610™ 1.2.1. Oven with oxygen sensor The gas/air mixture is burnt catalytically in an oven, which is kept at 812ºC with a burning spiral. The temperature is maintained with a temperature controller using a K-type thermocouple. -
Page 7: The Sample System (Scs)
INSTALLATION, OPERATION AND MAINTENANCE MANUAL – COSA 9610™ 1.2.2. The sample system (SCS) In the sample conditioning system (SCS), gas and air are mixed in a constant proportion, such that a small excess of air is present (± 2.5% oxygen) in the flue gas. The gas and air pressure, are equalized by a dome-loaded pressure reducer (or booster relay), where the gas pressure governs the air pressure. -
Page 8: Calibration Procedure
INSTALLATION, OPERATION AND MAINTENANCE MANUAL – COSA 9610™ 1.3. ALIBRATION ROCEDURE The analyzer can be calibrated in three different ways: • Single point calibration Only one calibration gas is used. The value of the gas is chosen middle of the measuring range. - Page 9 INSTALLATION, OPERATION AND MAINTENANCE MANUAL – COSA 9610™ The two-point calibration/validation procedure will be executed as followed: 1. Analyzer activates calibration/validation contact. 2. The procedure pauses for the specified “Calibration Start Delay” time for the external host to prepare for calibration/validation.

The COSA 9610™ can optionally be supplied on a 304L Stainless Steel freestanding frame. This frame is to be placed on a flat surface (i.e. concrete slab). Two holes (∅12) in the base of the frame enable the COSA 9610™ to be fixed to the floor 2.3.3. -
Page 14: Mechanical Connections
• Location and amount of connections may vary depending on type and execution of the analyzer. • Tubing connections on the COSA 9610™ are Swagelok double ferrule compression type fittings for imperial sizes. • Only seamless and annealed imperial size instrument tubing according ASTM A-249 at a maximum permissible hardness of Rockwell B-90 may be used. -
Page 15: Sample Supply
2.4.3. Calibration gasses Calibration gas composition is depending on range and process gas. COSA INSTRUMENT can advise suitable compositions. For a single range analyzer, 2 calibration gasses (low and high value) are recommended. -

SCS. For termination details see specific drawings. Signal cables The COSA 9610™ has multiple input and output signals, which can be split in two groups, analog and digital signals. For both groups, an NEC approved cable gland for use with multi core cables are foreseen. - Page 17 INSTALLATION, OPERATION AND MAINTENANCE MANUAL – COSA 9610™ Signal cables The COSA 9610™ has multiple input and output signals, which can be split in two groups, analog and digital signals. Please make sure that the cable glands used are EExd/NCE certified.

INSTALLATION, OPERATION AND MAINTENANCE MANUAL – COSA 9610™ Relationship of pressure differential (gas/air) versus Wobbe-Index with different air orifices and a fixed residual oxygen concentration of 5% (theoretically determined). It is therefore recommended that a residual oxygen concentration of 2.5% is chosen corresponding to the reference point. - Page 20 INSTALLATION, OPERATION AND MAINTENANCE MANUAL – COSA 9610™ Caution The adjusting screw is located in the gas compartment of the relay. When the insert is released, gas will escape. Be prepared before the relay is going to be adjusted, e.g. have the right equipment readily available, so the gas compartment has to be open for only a minimum of time.
