“…Bazooyar et al [14] made trails in a boiler with the biodiesel of various vegetable oils and found that the efficiency ranges from 14 -24%. Kermes and Belohradsky [15] carried out the experiments with preheated rapeseed oil methyl-ester at about 70 °C in a water-cooled horizontal combustion chamber. The emission of NO x is more compared to extra light heating oil combustion.…”

In the present work, straight sunflower oil and rice bran oil blended with diesel have been used as fuel diesel in a mini boiler. The thermal efficiency of the boiler and emission levels in the exhaust gases have been investigated by burning the oil blends of varying proportions ranging from 0-50%. An additional air supply system and compressed air atomization of fuel with a new burner have been used to improve the thermal efficiency of the mini boiler. Results revealed that the additional air supply improved the thermal efficiency up-to 7% and reduced the CO and HC emission up-to 40%. The use of compressed air atomization further increased the thermal efficiency up-to 4% and reduced the CO and HC emission up-to 70%.

“…To achieve this, a transesterification reaction of the VO with methanol, in a basic medium, was performed so as to give the corresponding fatty acid methyl esters (FAME). The combustion of both pure biodiesel − and its mixtures with diesel fuel − in conventional boilers has been widely studied, and the results were compared with derivatives of oil such as extra light heating oil and diesel fuel. It was generally found that biodiesel is a suitable fuel for domestic and industrial boilers regarding combustion effectiveness and low CO emissions.…”

“…It was generally found that biodiesel is a suitable fuel for domestic and industrial boilers regarding combustion effectiveness and low CO emissions. With regard to NOx levels, published data show that these depend on the quality of atomization and boiler operating conditions. , As a result, depending on experimental conditions, lower, ,,, equal, ,,, or higher ,,,, emissions than those using oil derivatives were obtained. Nevertheless, the main limitation of biodiesel lies in the long reaction times required to prepare it and its subsequent purification.…”

This work presents the experimental results from refined palm vegetable oil atomization and combustion processes in a low-pressure auxiliary air fluid pulverization burner. The physicochemical properties that define palm vegetable oil as a fuel (density, kinematic viscosity, heating value, and elemental analysis) were first determined. The fatty acid composition was then established by proton high-resolution nuclear magnetic resonance spectroscopy. A description was provided of a procedure based on direct photographic imaging in order to determine the macroscopic properties that define the atomization spray, spray tip penetration, and spray cone angle. The influence of varying the fuel and secondary air flows in the atomization and combustion processes was also studied. The polluting emissions and combustion efficiencies in the different test conditions and how these vary depending on the atomization parameters was then evaluated. In general, admissible combustion efficiencies were obtained, with CO and NOx emissions below permitted levels. Most of the experiments carried out showed that the lower the spray cone angle the greater the combustion efficiency.
