Experimental Study of Nozzle Hole Diameter and Air Volumetric Flow Rate on Flame Temperature of Used Oil-Fired Stove

Abstract

The utilization of used oil as fuel has begun to be used today even though only some people. Knowing how the interaction of nozzle hole diameter on fire temperature in portable stoves. This study used experimental research, by testing the value of the independent variable with (nozzle hole diameter (2, 3, 4) and variation of air volumetric flow rate, the response obtained (dependent variable) knowing the causal relationship of the study. This research processing method uses factorial ANOVA. see the interaction between independent variables on the dependent variable in addition to seeing the influence of independent variables independently on the dependent variation. The flame that produces the highest temperature is 900C in the 3mm hole diameter variation with an airflow rate of 0.004 mᶟ/s. The flame with T1 varies the diameter of the 4mm hole with an airflow rate of 0.006 mᶟ/s. Then the T2 flame has decreased graphically from the previous diameter at 3 mm hole diameter with air volumetric flow velocity at 0.006 mᶟ/s. The larger the hole, the smaller the air pressure, otherwise the smaller the diameter of the nozzle hole, the greater the pressure spread into the combustion chamber is better.
