AbstractThis paper presents the effect of products cooling on the pollutants emission of (carbon monoxide [CO], unburned hydrocarbon [UHC], nitrogen oxide [NOX], and Soot) from a continuous combustion chamber. Products cooling technique was accomplished by installing heat exchanger in the way of the exhaust gases. The water flow rate through heat exchanger was varied from 0 to 30 liters per minute with 10 liters per minute increment. With a droplet size of 80 µm for gas oil fuel and kerosene fuel, and local equivalence ratio was varied from 0.8 to 1.4. When using the products cooling technique it was found that the NOX is inversely proportional with increasing the water flow rate through heat exchanger with the maximum decrease in NOX emissions of 18.76%. But , CO , UHC and soot are directly proportional to increasing the water flow rate through heat exchanger as the maximum increase in CO , UHC and soot were (27.43%,26.32%,19.87%) respectively .also found the emissions from gas oil fuel more than kerosene fuel .
