PCA
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 –18 to 1200 ºC (0 to 2192 ºF)
• Primary-air / ambient temperature is in the range of –18 to 999 ºC
(0 to 999 ºF)
Optional . . .
• Differential pressure/draft in the range of ±70.0 mb (±28" H
2
O)
• 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 18.8%, and the Stack (Flue
Gas) temperature is not above 1200 ºC (2192 °F)
• Stack loss in the range of 0.1 to 99.9%
• Carbon Dioxide content in flue gas from 0.1 to a fuel dependent
maximum value in percent
• Lambda in the range of 1 to 9.95
• Carbon Monoxide* content referenced to 0% Oxygen in the range of
0 to 9,999 ppm on analyzers equipped with a CO sensor.
• Nitrix Oxide* content referenced to 0% 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
• Koks
• LEG
• LPG
• Oil #2
• Oil #6
• P-Coal (available in English, German, Dutch, French, Italian,
Polish, and Spanish languages)
• Biofuel (available in Danish, Finnish, and Swedish languages)
* 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 (CU & NU) referenced to
0% 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.
