G362x Stack Gas Oxygen Analyzing System

The G3620 Stack Gas Oxygen Analyzing System offers a decisive tool for optimizing boiler efficiency and reducing the oxygen content of exhaust gas.

The system is installed in the stack close to the boiler and measures under actual flue conditions. The sample is analyzed in situ without being passed through vulnerable sampling lines.

High Quality and Low Maintenance

The automatic simplified calibration ensures minimum maintenance. At regular intervals (freely configurable), the analyzer calibrates itself using instrument air. The automatic back-flushing of the probe head cleans the probe head from loose soot and dust.

Benefits to Economy and Environment

The fuel-air ratio in the burner is crucial to optimizing the combustion and boiler efficiency. With the G362x you can typically optimize combustion and save 3-5% fuel – in some cases even more.

Compared to the sheer volume of fuel consumption of marine boilers, the cost of installing a G362x Stack Gas Oxygen Analyzing System is only a minor investment. Its payback time will usually be a matter of months. As a result, you spare the environment of emissions and your budget of fuel costs.

Ejector probe and Diffusion probe

You can choose a stack gas oxygen analyzing system which is combined of an analyzing board with an ejector probe - type G3620 or an analyzing board with a diffusion probe - type G3621.

The ejector probe has a built-in ejector that drives the pump drawing the sample gas into the measuring chamber ensuring a fast response time. An ejector probe requires an estimated air consumption of min. 2l/min at 1 bar.

In the diffusion probe, the gas is diffused to the measuring chamber. Although its response time is not as quick as the ejector probe’s, it is sufficient for most industrial applications. Since the diffusion probe does not require any ejecting air, it will mean high cost savings for the owner. Furthermore, the simple design also ensures less and easy maintenance.
