Abstract:
In this work, the combustion of soya and rapeseed vegetable oils in a low-pressure auxiliary air fluid pulverization burner is carried out. The facility used has several parameters that can be adjusted to achieve maximum combustion efficiency and minimum flue gas emissions. These parameters are: the fuel flow supplied to the burner, the secondary air flow, the temperature and pressure of the combustion chamber. The latter two were adjusted by changing the cooling air flow in the combustion chamber and the dumper aperture located in the chimney. The work has been carried out in various stages. First, the physicochemical properties and fatty acid profile of the vegetable oils were determined. The combustion of the vegetable oils studied is then performed varying the burner adjustments, and analyzing regulated gas emissions. Once the optimum operating conditions have been established, each experiment is repeated eight times. The data obtained were then analyzed using the Shapiro-Wilk test and measures were found to be repeatable. Finally, multifactorial variance analysis (ANOVA) revealed that the secondary air flow and temperature of the combustion chamber have the most significant effect on CO2, CO and NOx regulated emissions.
