Maximize Efficiency, Minimize Emissions with SST’s Zirconium Oxygen Sensors

SST’s Range of Zirconium Dioxide Oxygen Sensors Have 25 Years Proven Operation in Combustion Controls Industry and many other applications which require harsh environment operation.

Many manufacturers of industrial boiler heating equipment have discovered the benefit of using SST’s Zirconium oxygen sensors to improve efficiency and reduce fuel costs. Zirconium Dioxide sensors are the most common type of sensor used in this field and the sensors from SST have been used reliably in boiler exhaust gasses for many years.

The can be used regardless of fuel type and are currently operating in gas, coal, oil, biomass and waste fuelled systems.


How Does the Technology Work?

The air to fuel ratio on boilers is set during commissioning. Over time, though, this falls away from the optimum because of changes in the fuel’s calorific value, changes in the combustion air temperature and wear in the control linkages.

Boiler controllers with SST Zirconia Dioxide Oxygen Sensors overcome these problems by continuously measuring the free oxygen concentration in the boiler flue – an accurate indicator of the air to fuel ratio. The controller then regulates the air rate to maintain the best combustion conditions at all times, maintaining maximum boiler efficiency, saving fuel and reducing emissions.

The full porous stainless steel cap allows free flow of the flue gases to reach the sensor while trapping any soot or debris which might otherwise lead to sensor malfunction. SST’s sensors will last for years even in badly regulated combustion processes before the dirt and pollution has any effect.
