Combustion is one of the most difficult processes to deal with in Nature and engineering. It involves simultaneous three-dimensional multiphase fluid dynamics, heat transfer (conduction, convection, and radiation), chemical kinetics, and the turbulent mixing of different species, all of which processes are coupled to each other. Chemical kinetics is heavily dependent on the temperature level, while thermal analysis is also strongly related to the energy utilization efficiency of the whole system when coal, oil, or gas is combusted. Thus, heat transfer is a very important issue to be considered. This chapter provides a brief review on heat transfer in combustion systems, with the three heat transfer modes – conduction, convection, and radiation – being discussed separately. For each heat transfer mode, the basic concept is introduced, including the important dimensionless parameters, theory, and some analytical or empirical correlations; heat transfer mechanisms, as applied to combustion systems, are then reviewed. Within the chapter, analytical or empirical correlations are provided for the thermal analysis of combustion systems, together with details of recent research into heat transfer modes in industrial combustion systems. It is hoped that the chapter will be helpful in both the design and thermal analysis of combustion systems.
