Robust Design and Reliable Monitoring

Green Instruments' oxygen analysis systems offer user-friendly and robust monitoring of oxygen in various industrial environments. Flue gas is the exhaust gas emitted by boilers. The G3620 Flue Gas Oxygen Analysis System provides data for controlling the fuel-air ratio in the combustion process and is used to regulate combustion and optimize boiler efficiency. In other words, the provided data is useful for energy optimization and environmental compliance. Insufficient oxygen supply leads to poor combustion, fuel waste, and energy loss, as well as increased black smoke and soot in the atmosphere. With the flue gas oxygen analyzer, savings of 3-5% on fuel consumption are achievable. Even when used in smaller boilers, the payback period is only a few months.

Easy Operation

The heart of every Green Instruments oxygen analyzer is a microprocessor-based unit with a simple menu structure that ensures a quick installation procedure. The oxygen analyzers are designed for easy part replacement and straightforward system calibration. They use a zirconia sensor cell based on proven and reliable sensor technology.

Control Combustion and Optimize Boiler Efficiency

The G3620 Flue Gas Oxygen Analysis System is a decisive instrument consisting of an oxygen analyzer, a sampling board, and an ejector probe with an oxygen sensor for optimizing boiler efficiency and reducing excess oxygen. Too much excess oxygen absorbs heat, meaning valuable energy is lost. The system is installed in the chimney near the boiler and provides real-time, wet oxygen measurements under actual exhaust gas conditions. This means that the flue gas is analyzed in situ without being passed through vulnerable sample lines. The analyzer is highly configurable, delivers excellent performance, and ensures reliable in-situ real-time monitoring.

Easy Calibration and Automatic Backflush

Calibrating the G3620 Flue Gas Oxygen Analysis System is simple and automatic, minimizing maintenance. Calibration is performed at regular intervals and uses instrument air. Automatic backflushing of the probe head keeps it clean from loose soot and dust.

The Ejector Probe

Ejector probes are used in areas with low or negative gas pressure. The ejector probe on the G3620 Flue Gas Oxygen Analysis System drives an ejector pump, which draws the sample gas into the measuring chamber. This ensures a fast response time.

Service and Support

The G3620 Flue Gas Oxygen Analysis System is compact and easy to install. Consumables are easy to replace. In case assistance is needed, such as replacing parts or retrofitting, Green Instruments provides full service and support to ensure optimal operation throughout the product's lifecycle.
