Flue Gas Oxygen Analyser

Ace Gas Analysers offers flue gas oxygen analyser, Model ACE 2000 Zirconia Oxygen Flue Gas Analyser is the simplest and least expensive basis for combustion control and can return as much as 90% potential fuel saving if the right oxygen sensor is used. The importance of minimising excess air is that for each 1% reduction of oxygen in the stack can give a 2% fuel saving. This is an "in-situ" on-line oxygen analyser package characterised by its robust construction and designed to measure oxygen concentration in the flue gas from the combustion processes. Typical application includes industrial power and process boilers, refinery process boilers, refinery process heaters, oxygen enrichment systems, wind boxes, incinerators and air pre-heater leakage. It can also be used for moisture analysis. Each analyser includes oxygen sensing probe, protective support shield, 6 metre cable, electronics package, reference air set and calibration gas rotameter in-built adaptor plate and accessories. The heart of the system is the Zirconia sensor, which when maintained at elevated temperatures gives an output (based on Nernst equation) which is a function of the gas constant, the absolute temperature, Faraday's constant, the natural logarithm of the rate of the partial pressure of oxygen on the two sides of the cell. This means if the temperature is held constant and air (20.9% oxygen) is used as reference air, the output becomes the inverse logarithm of the partial pressure of oxygen in the measured gas. The microprocessor-based electronics is housed in a rugged IP 65 (weather proof) enclosure. The electronics can be mounted close to the probe or in the control room with suitable cabling. The electronics is capable of giving standard log/linear output suitable for plant operation.
