Bacharach 450 User Manual

Introduction ECA 450
2 Instruction 0024-9400
• Performs data logging. A series of combustion tests can be automatically
started at user-defined intervals, and the data saved for reviewing at the
conclusion of the logging period. The data can be stored in either the
analyzer’s internal memory, sent to a personal computer, or both.
• Utilizes four sources of primary-air temperature information in the
following priority: 1) A thermocouple can be inserted into the primary-air
stream and plugged into the analyzer’s front panel T-AIR connector. 2) A
primary-air temperature reading can be made with the probe’s
thermocouple and stored in memory. 3) An external thermometer can be
used to take a primary-air temperature reading and then entered into
memory using the analyzer’s front panel keypad. 4) If no other primary-air
temperature source is available, the analyzer defaults to an internal case
temperature that is measured the on printed circuit board.
• Stores test identification that is manually entered by an operator. This
information is added to the test records as they are saved, and appears
within each test record when printed.
• Stores user name information that is manually entered by the owner or
user of the analyzer. This information appears at the top of each printout.
• Displays information in either English, French, or Spanish.
• Can be set up to automatically turn off the front-panel display to conserve
battery life.
1.3 Technical Data
The ECA 450 Directly Measures and Displays:
• Oxygen content in flue gas in the range of 0.1 to 20.9% O2.
• Stack gas temperature in the range of –4 to 2400 ºF (–20 to 1315 ºC).
• Primary-air in the range of –4 to 999 ºF (–20 to 999 ºC).
• Pressure in the range of ±27.7 inches of water column (±69 mb).
• Carbon Monoxide content in flue gas in the range of 0 to 4,000 ppm CO
(corrected for the presence of Hydrogen).
Optionally . . .
• Carbon Monoxide in the range of 4,000 to 80,000 ppm CO.
• Nitric Oxide in the range of 0 to 3,500 ppm NO.
• Nitrogen Dioxide in the range of 0 to 500 ppm NO
2.
• Sulfur Dioxide in the range of 0 to 4,000 ppm SO
2.
• Combustibles in the range of 0 to 5% gas.
The ECA 450 Calculates and Displays:
The following is true only when the measured Oxygen level is not above 16.0%,
and the Stack (Flue Gas) temperature is not above 2192 °F (1200 ºC)
• Combustion efficiency in the range of 0.1 to 100%.
• Excess Air in the range of 1 to 250%.
• Carbon Dioxide content in flue gas in the range of 0.1 to a fuel dependent
maximum CO
2
value in percent.
• Carbon Monoxide content referenced to a user defined percentage of
Oxygen in the range of 0 to 99,999 ppm CO.
• Differential pressure in the range of ±27.7 inches of water column
(±69 mb).
