Aiming at the increase in use of combustion technologies for heavy oil fuel containing a lot of carbon residue and in order to develop heavy oil fired burners having excellent environmental performance, Mitsubishi Heavy Industries, Ltd. (MHI) examined the structure of atomizers and swirlers, which are the main components of the burners, mainly using numerical analysis. It was confirmed that the developed structure attained a reduction in particle size by 38% in a spray test and that the developed swirler remained undamaged even after one year of operation in actual equipment. In this way, the effectiveness of MHI's burner development was verified. This paper describes the analysis technologies that were newly established in the burner development.
