PCA Technical Characteristics
2.0 TECHNICAL CHARACTERISTICS
The PCA Directly Measures and Displays:
• Oxygen content in flue gas in the range of 0.1 to 20.9 % O
2
• Flue gas temperature in the range of 0 to 2192 ºF (–18 to 1200 ºC)
• Primary-air / ambient temperature is in the range of 0 to 999 ºF
(–18 to 999 ºC)
Optional . . .
• Differential Pressure and Draft in the range of ±28" H
2
O (±70.0 mb)
• Carbon Monoxide* content in flue gas in the range of 0 to 4000 ppm
• Nitric Oxide* content in flue gas in the range of 0 to 1000 ppm
The PCA Computes and Displays:
When the measured oxygen level is not above 16.0%, and the Stack (Flue
Gas) temperature is not above 1832 °F (1000 ºC)
• Efficiency in the range of 0.1 to 99.9%
• Excess Air in the range of 1 to 250%
• Carbon Dioxide content in flue gas from 0.1 to a fuel dependent
maximum value in percent
• Carbon Monoxide* content referenced to a percentage of Oxygen in
the range of 0 to 9,999 ppm on analyzers equipped with a CO sensor.
• Nitrix Oxide* content referenced to a percenage of Oxygen in the
range of 0 to 9,999 ppm on analyzers equipped with a NX sensor.
Standard Fuels** Available for
Combustion Calculations:
• Natural Gas
• Oil #2
• Oil #4
• Oil #6
• Kerosene
• Propane
• Coal
* For the PCA 30, 35, 60, & 65, the display can be set up to show
either measured values of Carbon Monoxide and Nitric Oxide (CO
& NX), or show the calculated values of these gases (CF & NF)
referenced to Oxygen. In either case, all values are listed on the
printout of analzyers equipped with a printer.
** Custom fuels available upon request. Contact factory for details.
