OVERVIEW Rapid advances in the design of 'across the duct' infrared gas analyzers have
led to the general acceptance of this technique for the monitoring of gas levels
in flue gases of power generation boilers and large industrial process steam
boilers.
The CCO 5500 is designed to operate on duct widths of less than 26 ft (8 m)
at flue gas temperatures up to 572
o
F (300
o
C). Their rugged construction
makes installation extremely simple, and through the use of microprocessor
technology they have many advanced features:
• Local normalizing inputs for compliance with legislation requirements
• Serial data facility to allow communication between analyzers and a
central data logging station
• User-definable output in either mg/m
3
, mg/Nm
3
or ppm
• Four rolling averages are held - selectable from 10 seconds to 30 days
• Integral, back lit 32 character LCD provides diagnostic and
measurement information
• Plant status input to prevent emissions dilution during plant off periods
SYSTEM DESCRIPTION The CCO 5500 Carbon Monoxide (CO) Analyzer Monitor consists of four
items (Figure 1-1):
• An infrared transmitter unit to project a beam of infrared radiation
across the duct
•A receiver to measure that radiation
•A power supply unit to provide the necessary power rails, and
•A signal processor to compute the gas concentration from the signals
provided by the receiver unit.
