The Effect of Upper and Lower Limit Pressure on the Thermal Performance of Liquefied Petroleum Gas Stove

: The paper presents the effect of the LPG's upper and lower limit working pressure on the thermal performance of an LPG single-burner gas stove. The measurement method for determining LPG stove thermal performance is based on Indonesian National Standard (SNI). The recent standard is SNI 8660:2018 about low-pressure LPG and LNG/NG gas stoves for households. According to the SNI, the working pressure required by the standard is 280 ± 5 mmH 2 O (2.8 ± 0.05 kPa). In this study, the effect of gas stove thermal performance for the upper limit pressure was carried out at a working pressure of 290 mmH 2 O, and the lower limit pressure was carried out at a working pressure of 270 mmH 2 O. A regression method was applied to determine the effect of upper and lower limit pressure on the thermal performance standardization of single-burner gas stoves. At the 95% confidence level, the input pressure significantly affects the heat input but has no significant effect on the thermal efficiency. The results show that the range of input gas pressure on the heat input measurement is 280 ± 5 mmH 2 O with special attention to pressure stability, while the thermal efficiency measurement can expand to 280 ±
