CONCLUSIONS The needs of developing increasingly efficient burners in terms of pollutant emissions has led to the definition of a consolidated procedure for their planning. f To this aim, an integrated system of infrastructures for the study of the various aspects 0 aerodynamics and combustion has been created. h The mathematical construction of models, thanks to high hardware potentl' a I'l tl,e s an d to t de increasingly developing software, has reached very high levels of response. CFD allowed reduce reactor schemes to be defined and tested through detailed NOx kinetics. , d Such approach has permitted the development, in a short time, of a Low-NOx burner for Oll an gas, named TEA 111<2, with a NOx reduction of 650/0 and with smaller LlP between the windbox and the combustion chamber compared to the previous version. , , The same procedure allowed the development of the TEA-C burner prototype for coal obtammg a NOx reduction of about 500/0 compared to a traditional burner. 9 |
