RÉSUMÉ

In this work, the concept of a nonsprayed porous burner (NSPB) of liquid kerosene is presented by numerical and experimental studies. The porous media are designed and utilized for both evaporation and combustion processes. The NSPB consists of a porous evaporator (PE) and a porous combustor (PC). The kerosene complete evaporation within the PE is self-sustained via thermal radiation from the PC. Afterward, the vaporized kerosene and preheated air are mixed in the small mixing chamber which is located between two porous media. Then, the homogeneous combustion occurs in the PC, instead of heterogeneous combustion in conventional sprayed burner. The results show that the prediction of temperature profiles has similar trends to those of experimental. The NSPB can extend the operation conditions with higher turndown ratios (6:1) and wider equivalence ratios (0.52−0.84). The NSPB is a new strategy without spray atomizer to fulfill future requirements.
