Abstract:
In the rural part of India or any other developing and under developed nation, people use biomass and kerosene for cooking application because of the low cost as compared to LPG. The thermal efficiency of biomass is about 5 – 10 %. Severe usage of biomass not only lead to deforestation, but also create an imbalance of natural resources in the ecological system. Though, LPG is a clean fuel when compared to other fuels for cooking purpose, due to its high cost and less accessibility in remote areas, people in the rural areas cannot afford LPG. Hence, due to the low cost and easy availability of kerosene, low-income group people in rural, suburban and urban areas can certainly utilize kerosene for the cooking applications. Average thermal efficiency of pressure kerosene stove is 45 %. Kerosene stoves release huge amount of CO and NOx emissions in the form of exhaust because of its incomplete combustion. Therefore, it is of vital importance to incorporate modifications in the design of kerosene pressure stove. The main purpose of the design modifications is to utilise the input energy to the maximum possible extent and to minimize the pollutant emissions. A conventional combustion device is associated with free-flame wherein the combustion takes place in the open-air environment, in which convection heat transfer is dominant.
