India has the second largest population in the world. There are 33.6 million or 17.5% of the households in the country using LPG (Liquefied Petroleum Gas) as their primary cooking fuel. These comprised 7.845 million homes (or 5.67% of the population) in rural areas and 25.752 million (or 47.96% of the population) in urban areas. While the worldwide average growth rate for LPG demand was about 3.7% per year during the 1990s, it is estimated that India’s annual growth in LPG consumption was over 11% between 1999 and 2005. The largest growth rates in commercial sector will be in China and India; in 1985, 5% of the total world residential-commercial LPG consumption was in these two countries, but by 2005, this consumption raised to more than 20% of the world total. Existing designs of most conventional LPG stoves have typically relied on open combustion flame, where a large amount of energy loss with the flue gas arises, resulting in relatively low thermal efficiency. The development of combustion equipment (LPG stove) must be directed at environmental compatibility, high efficiency, high intensity, plus low capital and operating costs. In this project work, our aim is to improve the overall efficiency of the stove by recovering waste heat. The stove we have modified which recovers waste heat with the help of water, has a higher overall efficiency than the conventional stove. The modified stove utilizes the empty space to store water which acts as a heat storage medium.
