Abstract

This paper presents the effect of varying operating conditions on pollutantsemission (carbon monoxide [CO], unburned hydrocarbon [UHC], and Soot) fromconstant pressure burner. In this research a liquid fuel used are gas oil andkerosene .The operating conditions which taken in account are atomizationpressure, inlet air temperature, equivalence ratio, as well as type of fuel.It is found that the Carbon monoxide and Unburned hydrocarbon are inverselyproportional to inlet air temperature with maximum decrease of (95%, 43%)respectively. In contrast, soot is directly proportional to inlet air temperature as themaximum increase in soot emission is 170%. Carbon monoxide , Unburnedhydrocarbon , and Soot are inversely proportional to Atomization pressure as themaximum decrease in Carbon monoxide , Unburned hydrocarbon, and sootemissions are (56.5%, 37.4%, 76%) respectively. The relation between Carbonmonoxide, Unburned hydrocarbon, and soot with equivalence ratio is directlyproportional as maximum increase in Carbon monoxide, and Unburnedhydrocarbon emissions are (130%, 81 %,) respectively, while soot emissions is 190%. Emissions from a constant pressure burner depend on the physical and chemicalproperties of fuel used, such as (viscosity, surface tension, volatility, the ratio ofhydrogen atoms number to carbon atoms number (H/C), and lower heating value).it is found that the maximum increase in Carbon monoxide, Unburnedhydrocarbon, soot emissions from gas oil are generally higher than those fromkerosene fuel by (72%,17.5%,38%) respectively`.
