説明

With a view to save fuel, the use of a regenerative burner as a heating source has been spreading in the field of industrial furnaces. By combining a burner with a regenerative air preheater, a second generation regenerative burner-the Rotary Regenerative Combustion System (RRX) has been developed, which makes for lower emissions of air pollutants and compactness, in addition to fuel savings.<BR>In this paper, heat transfer characteristics of RRX were deduced theoretically based on the heat transfer theory of a regenerative air preheater and investigated experimentally using two test rigs. A commercially operating fired heater was revamped in the summer of 1994 to install 3 sets of RRXs, and it has been sucessufully operated for one year.<BR>As a result, it was recognized that the heat transfer rate in a RRX can be predicted within ± 10% of deviation, by considering not only convective but also radiative heat transfer. Furthermore, it was confirmed both theoretically and experimentally that fuel efficiency exceeding 90% was stably attained in a commercialized fired heater. Around 60 ppm of NOx emission (as dry, 6% O2) was also measured, although the preheated air temperature was calculated as high as 930 K.
