THE COMPARATIVE ANALYSIS OF NATURAL GAS, LPG, AND GASOLINE IN GENERATING ON-SITE ELECTRICITY FOR RESIDENCES

Abstract

This study targets at examining electricity generation and the system parameters have been compared for household needs by on-site natural gas, LPG and gasoline generator as well as the heating of the residence by the released exit gas during the working of the system. In this study, the issue of individual electricity generation has been experimentally analysed by a sample application. Natural gas, LPG and gasoline have been converted into electrical energy by means of an internal combustible motor and an alternator. The system has functioned at full and low load. Working at full load, the generation of 1 kWh costs $0.23 with natural gas, $0.69  with LPG and $1.07 with gasoline whereas at the low load, the costs of 1 kWh for the indicated fuels come out to be $0.25, $0.93 and $1.55 respectively. The sufficiency of the waste heat, which is obtained through the burning of the indicated fuels, in residence heating and meeting the hot water need has been analysed. Depending on the working capacity of the system, it has been noted that the hot water obtained vary between 38°C and 50°C.
