PENGARUH SUPLAI UDARA TERHADAP KARAKTERISTIK BENTUK DAN TEMPERATUR NYALA API DARI UAP PREMIUM

Abstract

The scarcity of LPG gas that often occurs in Indonesia often makes Indonesian citizens
uneasy. This scarcity led many researchers to conduct research that could reduce the
dependence of Indonesian citizens with LPG gas. In this study, researchers conducted
tests related to the use of premium steam as fuel. This test is carried out by varying the
air supply, where this supply has been determined at 2 km/cm2
, 3 km/cm2
and 4
km/cm2
, in addition to the air supply this test also performs fire temperature
measurements using thermocouples and data logers, where the location of the
thermocouple has been located at points 1 cm, 3cm and 5 cm from the mouth of the
nozzle. Based on the test results, the shape of the flame from variations in the air supply
obtained the best and stable results were in the 3 km/cm2
air supply, while the other for
the 2 km/cm2
air supply was found to be unstable fire and for which the 4 km/cm2
fire
air supply looked large and unstable. Whereas for the highest temperature of the three
placement points the thermocouple is located at the top point with a distance of 5 cm
from the mouth of the fire with an average temperature of around 900oC and the lowest
temperature is at 1 cm from the nozzle mouth, where the temperature is at 400oC to
550oC, in addition The temperature stability is in the air supply of 3 km/cm2
