Biomass
Biomass is the fuel normally employed in water tube, or thermal oil boilers for the generation of super-heated vapour, heating the thermal oil and/or providing heat for a range of applications.
It is common to generate high levels of CO2 and unburnt and black gases in this type of boiler as a result of combustion with an excess or deficit of comburent air. It is therefore essential to control the atmosphere and correctly regulate and monitor the input of combustion air.
Continuous changes to the working and fuel conditions (ambient humidity, morphology of the product, temperature and atmospheric pressure, etc.) mean these types of installations usually have a low energy performance.
The continuous control of the %O2 in the boiler burner assembly can result in savings of up to 15% in the consumption of biomass.
