Performance Analysis of LPG Cook Stoves with Modifications

Abstract

Liquefied Petroleum Gas (LPG) is a most popular fuel for domestic uses as heating and cooking applications, because of its high heat content and cleaner combustion characteristics. This paper investigates, the performance of LPG cook stove commonly used in Indian household level, through the fuel injector (nozzle) size and material of burner. It has been observed that with the increase in fuel injector size, first thermal efficiency increases at optimum value then decreases. It has been found that the maximum thermal efficiency of domestic cook stove is 68% for a brass burner and 64% for cast iron burner at the same fuel injector size of 0.77 mm.
