“…After combining IBE with diesel, spray evaporation characteristics vastly improve, according to experimental findings. Moreover, the ambient temperature had a significant effect on the spray evaporation of both pure diesel and IBE/diesel blends, with an increase in temperature resulting in smaller spray streams [38]. To enhance the pre-evaporation of liquid spray in confined spaces, electrostatic fields to control the location of electrically charged droplets of fuel have been studied [39].…”

Due to the current global crises related to fossil fuels (prices up and sources shortage) and in order to diminish the remnants and the negative effects of harmful gas emission (CO and NOx), the fielded researchers and academics try to find alternative source of fossil fuel. Bio fuels consider one of promised source of clean energy. Palm vegetable oil widely separated in Malaysia which considered one of dominant production of this oil globally. Atomization and evaporation radically represent a challenge when using liquid fuel especially fuels with high viscosity and density which is not easy to atomize and evaporate without pre-heating or blende it. A numerical investigation has been proposed to do comparison between two different external evaporative chamber and internal evaporation without using conventional liquid fuel evaporation methods. Findings revealed that both configurations have a good performance in term of emission concentrations and turbine inlet temperature (TIT) which was about 899 C with chamber using internal recycle tube evaporation with CO emission about 183 ppm with outer pre-evaporation chamber. Chamber with internal evaporation was chosen due to technical and fabrication reasons. Besides that, a six different inlet and exhaust ducting ports tested with the chosen chamber with internal recycle tube evaporation chamber, all configurations revealed a non-symmetrical flame flow near chamber exhaust which is not desirable as it will cause turbine unstable operation. The configuration with square duct exhaust was suitable with stable and symmetric flame flow field and slight small CO emission about 312 ppm.
