Highly preheated lean combustion

The terms “high temperature air combustion (HiTAC)” and “moderate and intense low-oxygen dilution (MILD)” combustion have only recently been defined. First published in the Combustion Institute Proceedings in 1998 (Katsuki and Hasegawa, 1998) and then in the Mediterranean Combustion Symposium Proceedings in 2000 (de Joannon et al., 2000), the definitions of these terms arose from a series of publications which have stressed features of interest pertaining to energy conversion and pollutant formation reduction. Proceedings papers concerning HiTAC (Crest, 2000; [HiTAC, 2000] and [HiTAC, 2002]) have added information on possible variants of the process. The review paper of Cavaliere and de Joannon (2004) and the monographic papers of (de Joannon, et al, 2000) and (de Joannon, et al, 2007) and Peters (2001) have discussed the possibility of extending the application of MILD combustion by studying the process in a simple well-stirred reactor. Although classifying a process as HiTAC or MILD combustion is straightforward when the process is evaluated based on its beneficial effects, it is not always clear to which elementary process these effects should be attributed
