The Green Instruments G3621 is a Stack Gas Oxygen Analyzing System which provides user-friendly and robust oxygen monitoring in marine environments. Stack gas is the exhaust gas which is emitted from ship boilers. The G3621 Stack Gas Oxygen Analyzing System provides data for controlling the fuel-air ratio in the burning process and is used for controlling combustion and optimizing boiler efficiency. Insufficient oxygen supply leads to poor combustion, fuel waste, and loss of energy as well as more black smoke and soot in the atmosphere. With the stack gas oxygen analyzer, savings of 3-5% in fuel consumption are achievable.
The G3621 Stack Gas Oxygen Analyzer comes with a microprocessor-based unit with a simple menu structure to ensure fast set-up. The oxygen analyzers are designed for easy replacement of parts and simple system calibration. They use a zirconia sensor cell, which is well-proven and reliable sensor technology.
The Green Instruments G3621 consists of an oxygen analyzer, a sampling board and a diffusion probe with an oxygen sensor for optimizing boiler efficiency and reducing excess oxygen. Too much excess oxygen absorbs heat, which means valuable energy is lost. The system is installed in the stack close to the boiler, providing real-time, wet oxygen measurements under actual exhaust gas conditions. This means that the stack gas is analyzed in-situ without being led through vulnerable sampling lines. The analyzer is highly configurable, delivering outstanding performance and reliable in-situ real-time monitoring.
