Abstract

The major aim of the present work is to use the self-made burner with the co-axial jet pattern to achieve the Moderate or Intense Low-oxygen Dilution (MILD) combustion in a I-shaped Recuperative Radiant Tube (RRT) and demonstrate its potentiality and superiority using experiments. For this end, the performances (e.g. uniformity of tube wall temperature as well as NOX emission) should be first explored using the traditional firing (conventional combustion) mode. The conclusions drawn suggest that, despite considerable efforts to burner optimization, it is still relatively difficult to further improve the performances. As a result, we modified the structure of I-shaped RRT to transfer the mode from conventional to MILD combustion and the remarkable upgraded performances are yielded. Moreover, the MILD combustion characteristics are verified to be governed by three critical factors (i.e., the recirculation ratio KA, flue gas temperature Tf and oxygen volumetric fraction in oxidizer fO2), and the quantitative relationship between the noted three for establishment conditions are discussed. It is found that, increasing fO2 from 0.18 to 0.30 makes the prerequisite KA significantly rise from 0.36 to 0.49 and the corresponding Tf increase from 994 K to 1341 K, to sustain the MILD combustion mode. Based on the experimental data, the analysis of stability limits suggests the narrowed MILD combustion region with the increase in fO2, especially at the situation of fO2 over 0.25. The results obtained overcame the substantial gap between the MILD technology achievement and co-axial-jet pattern in a narrow and small space. Accordingly, the present work seeks to further effectively extend the establishment mechanism of MILD combustion and theoretically guide the parameter optimization of such a common industrial heating item as the I-shaped RRT.
