ABSTRACT

The process of elaboration and consequent verification of mathematical model of NOx production during wood combustion based on the dimensional analysis theory is presented in this paper. The model is based on selected physical quantities which can be measured continually during the boiler operation. Primarily, the model was elaborated for boiler type VERNER V210 of 20 kW performances and its validity was also verified for the same construction type of boiler of lower performance (14 kW). Lump wood of lower calorific value of approximately 15 MJ∙kg-1 was used as a fuel in the boilers. The results showed that the dimensional analysis can be applied to describe such a complex phenomenon as the NOx production during wood combustion.

Keywords: mathematical modelling, nitrogen oxides, dimensional analysis, wood combustion
