World class oxygen analysis technology enables optimal combustion efficiency and compliance with international, environmental legislation

Fuji Electric offer an oxygen analyser modular platform, built around zirconia sensor technology, which provides the perfect solution for combustion control in boilers, incinerators and furnaces. This cutting-edge device facilitates the reduction of CO₂, CO, SOx, and NOx emissions and saves energy – and extends the combustions plant’s longevity.

Fuji’s analyser is widely used to continuously measure oxygen concentration in combustion exhaust gas emitted from industrial boilers and furnaces. It is ideal for combustion management and control, in applications such as waste incinerators as well as all sizes of boilers, to control combustion and therefore enable a considerable reduction in energy costs.

This instrument’s measurement principal is based around zirconium oxide, that conducts oxygen ions when heated. The analyser measures oxygen concentration by sensing the electromotive force generated by the difference of oxygen concentration in air and the sample gas.

Fuji have years of experience in providing state-of-the-art instrumentation suited for some of the harshest environmental and industrial conditions. Their technology is ubiquitous in some of the most demanding industries such as steel, petroleum and petrochemical, energy, ceramics, food and beverage, paper and pulp and textiles.

This versatile and highly user-friendly analyser platform transmits measurement data securely and reliably via the new Hart Protocol with RS-485 standard electrical signalling. It has been designed to facilitate the reduction of excess air in the combustion process, which leads to a significant reduction in costs by enhancing combustion efficiency. The zirconia sensor, which has a significantly longer life expectancy than others of its kind, is quick and easy to replace, which means far less maintenance and its associated delays. No air supply or flue gas extraction is required – and the instrument typically generates measurement data within 4-7 seconds, as well as performing predictive and advanced diagnostics. 

This device also includes several important safety features. The converter shuts down the power supply to the detector if a thermocouple burnout is detected, it can also be quickly and easily cut off in emergencies and a key lock facility significantly reduces the probability of operator error.
