Abstract

To control and reduce emissions for combustion devices, numerical
simulations are becoming increasingly important. In this study, numerical
simulations of a domestic methane burner are performed to predict
the temperature profile and the formation of carbon monoxide and
nitric oxide. A detailed reaction scheme, as well as a detailed transport
model was used in this two-dimensional study. We consider premixed
laminar flames at low flow speed. Thenumerical simulations are performed
with the object-oriented C++ code Gascoigne (Becker and Braack, 2001),
which was developed recently and has the adaptive-gridding capability
allowing minimization of the error in the numerical simulation with
respect to certain functionals, for example, local values ofspecies
mass fraction and mean value of temperature or heat release. Acomparison
with experiments as well as a parametric study aimed at the minimization
of pollutants were carried out. The optimal parameters to guarantee
a good compromise between flame stability and toxic emissions are
presented.
