Heavy Fuel combustion model

Abstract

•Large portion of Heavy Fuel Oils (HFOs) are burned to meet the energy demand in Saudi Arabia. It is a relatively cheap and widely available fuel. •The combustion processes associated to HFOs present numerous complications from both the environmental and technical point of view. •Several aspects concerning the combustion behavior and the physics of the fuel itself are not known. A numerical description of physical and chemical phenomena involving HFOs is very challenging. •The methodologies developed for HFOs are suitable to describe other relatively heavy fuels involved in chemical processes like crude-oil and bio-fuels. •Various fuel modifications, such as different asphaltene percentages and emulsions, are studied to improve the combustion performance as well as reduce the environmental impact, a correct prediction of these phenomena would save the costs associated to the experiments.
