Description and Specifications
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.
