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