Abstract

In this chapter, we conduct a comprehensive study of MILD and MILD oxyfuel combustion from the viewpoints of both the first and the second law of thermodynamics. In the beginning, kinetic modeling is performed for methane in a zero-dimensional reactor ignoring molecular diffusion and turbulent mixing. The initial boundary conditions of reactor inlet temperature as well as mixture oxygen concentration are identified for realizing the MILD combustion regime of methane at different equivalence ratios. Subsequently, more realistically, the flame structure and entropy generation characteristics of biogas MILD oxyfuel combustion are examined in a counterflow diffusion flame by varying the preheating temperature and oxygen concentration of the oxidant. This chapter will provide useful information on establishing and optimizing MILD and MILD oxyfuel combustion.
