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`.
