Quantifying NOx for Industrial Combustion Processes

Modelling NOx-Formation in Combustion Processes

As the regulations of pollutant emission is getting more and more strict, models of pollutant formation, as a part of system level models for control design, are needed. In this thesis NOx (nitrogen oxides) formation is modeled. A method is developed to mix equilibrium and non-equilibrium reaction equations to model NOx formation in combustion processes. This algorithm reduces high-index DAE sy...

Low NOx Combustion Technology for Minimizing NOx

A noble low NOx combustion technology, based on partial oxidation combustion concept in a fuel rich combustion zone, is successfully applied in this research. The burner is designed such that a portion of fuel is heated and pre-vaporized in the furnace then injected into a fuel rich combustion zone so that a partial oxidation reaction occurs. The effects of equivalence ratio, thermal load, and ...

Industrial Combustion Boilers

PROCESS AND TECHNOLOGY STATUS – Combustion boilers are widely used to generate steam for industrial applications and power generation. While all kinds of energy sources fossil fuels, biomass, nuclear and solar energy, electricity can be used to generate heat and steam, the scope of this brief is limited to combustion boilers using fossil fuels and biomass. Boilers can be grouped into two broad ...
