This necessitates that in addition to the obtainable source of power such as coal, water, petroleum etc. other sources of energy should be searched out and new and more efficient ways of producing energy should be devised. Power generation from biomass becomes attractive way for energy generation due to their high energy potential and less pollutants. In this paper we present the study and literature survey on power generation of biomass. Keywords: Biomass, coal-biomass briquette, proximate analysis, calorific value, energy value. I. INTRODUCTION Today fossil fuels such as oil, coal and natural gas represent the prime energy sources in the world (approximately 80% of the total use ). However, it is anticipated that these sources of energy will be at a low level within the next 40–50 years[14]. In the renewable energy scenario dominated by solar, wind and micro/mini hydel, biomass is beginning to look promising in the view of new emerging technologies. The renewable energy sources Biomass provides both, thermal energy as well as reduction for oxides. Biomass being a product of natural resources viz. land, water, air and sun’s energy, gives much hope as an alternative, reliable and renewable source of energy. Biomass is an organic matter produced by plants, both terrestrial and aquatic and their derivatives [12]. The two different types of non-woody biomass species are taken, one is Cassia Tora (Chakunda) and another is Gulmohar (Krishnachura).These biomass species were cut into small pieces and there different component like leaf, nascent branch and main branch were separation from each other. These biomass materials were air-dried in cross ventilator room for around 20 days. When the moisture contains of these air-dried biomass sample came in balance with that of the air, they were crushed in mortar and pestle into powder of -72 mess size. The sample of Coal for making the blend was collected from coal mines. These materials were than processed for the determination their proximate analysis and Energy values. II. ENERGY GENERATION FROM BIOMASS A brief description of the technologies for energy generation from biomass is as follows: A. Combution In this process, biomass is directly burned in presence of excess air (oxygen) at high temperatures (about 800°C), liberating heat energy, inert gases, and ash. Combustion results in transfer of 65%–80% of heat content of the organic matter to hot air, steam, and hot water. The steam generated, in turn, can be used in steam turbines to generate power. B. Transesterification The traditional method to produce biodiesel from biomass is through a chemical reaction called transesterification. Under this method, oil is extracted from the biomass and it is processed using the transesterification reaction to give biodiesel as the end-product. C. Alcohlic fermentation The process of conversion of biomass to bio-fuels involves three basic steps:  Converting biomass to sugar or other fermentation feedstock  Fermenting these biomass-derived feedstock using microorganisms for fermentation.  Processing the fermentation product to produce fuel-grade ethanol and other fuels. C. Anaerobic Digestion In the absence of air, organic matter such as animal manures, organic wastes and green energy crops (e.g. grass) can be converted by bacteria-induced fermentation into biogas (a 40%-75% methane-rich gas with CO2 and a small amount of hydrogen sulphide and ammonia). The biogas can be used either for cooking/heating applications, or for generating motive power or electricity through dual-fuel or gas engines, low-pressure gas turbines, or steam turbines. D. Pyrolysis Pyrolysis is a process of chemical decomposition of organic matter brought about by heat. In this process, the organic material is heated in absence of air until the molecules thermally break down to become a gas comprising smaller molecules (known collectively as syngas). The two main methods of pyrolysis are “fast” pyrolysis and “slow” pyrolysis. Fast pyrolysis yields 60% bio-oil, 20% bio-char, and 20% syngas, and can be done in seconds. Slow pyrolysis can be optimized to produce substantially more char (~50%) along with organic gases, but takes on the order of hours to complete. E. Gasification In this process, biomass reacts with air under extreme temperatures and results in production of producer gas, to produce power (or) react with pure oxygen to produce synthesis gas for fuel production. The combustible gas, known as producer gas, has a calorific value of 4.5 - 5.0 MJ/cubic meter. A wide range of biomass in the form of wood or agro residue can be used for gasification [14]. III.
