INTRODUCTION
1. General
Energy is an essential input for economic development and for improving the quality of life. India’s per capita consumption of commercial energy is only one eighth of global average. Industrial countries with only 22% of world’s population produce 54% of total global energy and consume 84% of it. On the other hand, developing countries with 78% of world’s population produce only 46% of total energy and consume just 16% of it. About 2.4 Billon people used the traditional biomass mainly for cooking and heating essentially all of those uses traditional reside in developing countries and most of them lives in rural area. Low income and lack of access to alternative, modern fuel explain their choice of traditional energy supply. About 46% of the total energy consumption of India is through cooking energy. The rapid growth in world population has created manifold rise in energy consumption. The resulting energy shortage necessitated research and development in alternate and local resources.
1.2 Bio- energy utilization
In rural areas for cooking, cookstoves are used generally based on wood. Wood is primary energy source for more than one third of world’s population. In many of these areas 80 to 90% of households depend on wood as primary source of energy. About 70% of wood, which is cut in the forest used only for cooking purpose in rural areas. Approximately 150 million of wood is burnt for cooking every year in India. It is therefore necessary to conserve cooking energy by every possible means.
1.3 Fuel and their types
What is fuel? Any source of heat energy is called fuel. The term “Fuel” includes all combustible substances that combine with oxygen from the atmosphere with the evolution of large amount of heat capable of being economically applied to domestic and industrial purpose.
Types of fuel -
There are three types of fuels: -
1. Solid fuel- It includes coal,
