A simple device to reduce the wastage of cooking gas

E.M. Ranatunga, W.G.D. Dharmaratna


We have invented a simple device to reduce the wastage of cooking gas. The main objective is to reduce the energy loss to the surroundings due to convection, radiation and conduction from pans with spherical bottoms like thachchiya used in cooking traditional food such as hoppers. In particular, the heat loss to the surroundings between the burner and the surface of the cooking pan is considered here. The efficiency of the device is compared with that of the bare pan by measuring the time taken to boil a fixed amount of water while keeping other conditions the same. The result indicates that the device reduces the gas consumption by about 23%. The device can be easily manufactured locally at low cost for practical applications.
