Analysis of the Flame and Spray Characteristics of Renewable Fuel in a Semi-Industrial Boiler

This study investigates the spray and combustion characteristics of a diesel and biodiesel fuel blend in a semi-industrial boiler. The principal objectives are to gain knowledge about combustion dynamics and improve the efficacy of alternative fuels. This research inquiry concerns biodiesel blends, with a particular emphasis on evaluating the effects of distinct blends and particular biodiesel varieties, including Dill, on flame temperatures and discharge patterns. The results indicate that the average flame temperature increases when biodiesel-type Dill is incorporated into a BD60% blend compared to conventional diesel fuel. The increase in temperature that was noted implies that specific varieties of biodiesel may enhance the efficiency of combustion in semi-industrial environments. Moreover, the study examines the ramifications of augmenting the fuel blend's biodiesel content. Elevated biodiesel concentrations increase densities and viscosities, thereby inducing growth in droplet diameters throughout the atomization process. It complicates the process of identifying optimal combustion conditions. The narrower spray width and smaller spray angle demonstrate how crucial it is to comprehend the properties of fuel to atomize and fire it effectively. The research demonstrates that biofuels, including biodiesel mixtures, can be seamlessly integrated into semi-industrial furnaces without necessitating any modifications. The compatibility of these biofuels with modern industrial furnaces emphasizes their potential as a dependable and adaptable energy source. According to the study's findings, increasing the use of biodiesel blend fuels may improve operational and environmental efficacy in industrial settings.
