Oxygen attack in boilers - Lenntech

The steam heats the water to the steam saturation temperature and removes the very last traces of oxygen. Deaerated water falls to the storage space below where a steam blanket protects it from recontamination. It is usually stored in a separate tank.

Boiler Combustion Efficiency | Zirconia Oxygen Sensors

Setting the boiler to burn with excess oxygen is the normal solution to reducing emissions. SSTs Zirconium Dioxide oxygen sensors can help customers optimise their boiler combustion efficiency within the oil coal gas and biomass boiler market. Results of incorrect combustion include fuel waste an increased level of toxic emissions and potentially damaging the combustion system.

Steam Boiler Types Construction and Working Principle ...

What is a steam boiler? A boiler or a steam boiler in simple words is a device used to generate the steam at a desired pressure and temperature by transferring heat energy which is generally produced by burning fuel in order heat the water to change it to steam. The steam used in the boiler is used for external purposes i.e. electricity generation heating or other industrial purposes.
