ABSTRACT

This research is aimed to describe the influence of mixing kerosene and  wasted cooking oil in variation of percentage that is used as fuel of stove with pressure tank. Description of those influences are average of the fire temperature, fuel flow rate, and usage efficiency of fuel heat. Percentage of kerosene were  30%, 40%, 50%, 60%, 70% (by volume) and initial pressure in fuel tank 0,4 kPa. The result shew that flare temperature rise if percentage of kerosene rise.  The avarage of each  temperature were 534.11 ^oC for  30% kerosene, 538.47 ^oC (40%), 541.63 ^oC  (50%),  543.73 ^oC (60%),  and 546.97  ^oC  (70%).  The mass flow rate of fuel were 44,867 gr/minute for 30% kerosene, 44,082 gr/minute ( 40%),  42,308 gr/minute (50%),  41,803 gr/minute ( 60%) and  40,734 gr/minute for 70% kerosene. The average of fuel flow rate was 50,949 ml/minute. The efficiency of stove with pressure tank rise if the percentage of kerosene rise, i.e   4,393 % for 30% kerosene,  5,041% ( 40%), 6,452 % ( 50%),  8,162 % ( 60 %) and 9,164 % for  70% kerosene.
