Why Monitor Flue Gas?

In an ideal combustion process, fuel and air burn
stoichiometrically to yield only heat, water vapor and
carbon dioxide. In reality, burners age, mixing is
imperfect, caloric value of fuel varies and firing rates
change. These factors change the amount of air required
for safe and efficient combustion of fuel. Accurate flue
gas analysis minimizes fuel costs and reduces pollution
in all combustion processes.

Combustibles applications typically trim burner air supply to
run excess oxygen at an optimal level to ensure complete
combustion. Reducing excess oxygen reduces fuel costs by
improving combustion eff iciency.

OxyTrak 390 Series_A Step Ahead of
Traditional Flue Gas Analyzers

The OxyTrak 390 combines state-of-the-art
measurement technology with a unique sampling
design. The result is an accurate, low-cost analyzer that
stays on the job for extended periods with minimal
maintenance. It responds in seconds to changes in flue
gas concentrations of oxygen and/or combustibles,
constantly providing the information you need to keep
your boiler or furnace operating at maximum efficiency.
OxyTrak 390 special design features include:

Stable, Accurate, Wide-Range Oxygen Sensor

The zirconium oxide oxygen sensor, is housed in a
furnace that maintains the O2sensor at a steady 1292°F
(700°C). The temperature stability improves accuracy
and extends the sensor’s life.

Corrosion-Resistant Design

The manifold heater block located at the sample inlet
prevents manifold corrosion due to flue gas acid
condensation and corrosion is prevented, ensuring
maximum analyzer life with minimum maintenance.

Optional Platinum-Catalyst Combustibles Sensor

A unique platinum-catalyst sensor is available to
measure levels of combustibles (CO plus H2). This is
useful for detecting incomplete combustion or defective
burner equipment.

Simple Installation

The OxyTrak 390 can be installed on a flue or furnace on
an existing flange mount. Because it utilizes the ex situ
convection loop design, reference air is not needed.

Fast, Easy Routine Maintenance

Calibration is easily achieved by introducing a calibrated
gas through the convenient calibration port and making
an automatic adjustment via the display controller. For
sensor replacement, there is no need to remove the
entire analyzer from the flue. Since the sensor is ex situ,
it can be quickly removed with basic tools.

Plug-Resistant Sample Path

A diffusion-based sampling technique greatly reduces
the entry of particulates into the analyzer. If necessary,
quick and easy cleaning is possible without
disassembling the unit.
