Flue gas emissions of the combustion of gasoil formulated with a mixture of Mexican oils in an experimental furnace

The quantification of emissions from the open chamber combustion of a 1 wt. % sulfur gasoil is presented. Three different gasoil formulations were tes ted in a typical burner using steam as aid for fuel injection. The componen ts of the gasoils were derivatives of a mixture of 42 vol. % of Maya heavy crude oil with 58 vol. % of Isthmus light crude oil. The influence of fuel flow as well as oxygen concentration on the emissions of the combustion pro cess was determined using two levels for each parameter. All NOx and SOx em issions were within the limits of the standard, where as the particulated m atter went beyond the limits when a 3 wt. % oxygen concentration was used. The level of particulated matter satisfies the standard when a 5 % oxygen c oncentration was used. The gasoil composition was found to influence the ef ficiency of the burner when primary heavy oil was used to formulate the gas oil. The main effect is reflected on the increase of particulate matter emi ssions.
