Swirling Flame Combustion of Heavy Fuel Oil Blended with Diesel: Effect of Asphaltene Concentration

Heavy fuel oil has an energy density content comparable to distillate fuels but a very high viscosity that necessitates extra heating before spray combustion inside boiler. is also characterized by asphaltenes, carbon residues, trace metals, such as vanadium and nickel, fuel-bound nitrogen, sulfur. Asphaltenes are heavy polycyclic aromatic compounds with embedded heteroatoms significantly affect the physico-chemical properties of fuels; this makes them difficult burn leads formation large cenospheres (lightweight, inert, hollow spheres), due inefficient burning process. The primary goal study experimentally investigate influence asphaltene concentration on HFO under swirling flame, finally reducing gaseous solid pollution. We tested samples containing concentrations 4, 6, 8, 16, 24 wt.%, prepared blending light diesel pure asphaltenes HFO. This work provides quantitative information about effect different contents viscosity, density, value, thermogravimetry air N2, flame characteristics, including analysis particle emissions. results indicated in was critical factor for incomplete increased sample. Reducing improves its characteristics performance reduces emissions sulfur metal elements.
