Evaluation of the solid particle from heavy fuel oil and its formation trend

Abstract

This experimental study aimed to comprehensively classify all types of solid particles formed during the heating process of heavy fuel oil and investigate the effects of adding light fuel additives on these particles. Heavy fuel oil is a significant energy source due to its affordability and efficiency. However, pollution, especially the emission of suspended particles, threatens nature and human health. This study identified four particles formed during the heating process of heavy fuel oil droplets until combustion. It was shown that these particles have unique characteristics in terms of size, physical characteristics, temperature conditions and formation process. Temperature behaviour, droplet size, and ignition delay time were carefully investigated. Also, the addition of lighter fuel changes the behaviour of heavy fuel oil and affects the temperature range and diameter size change for solid particle formation. This study provides a deeper understanding of the nature of solid particles in heavy fuel oil and their formation, which is crucial for developing effective strategies to reduce their harmful effects.
