biomass energy in bangladesh

Based on life-cycle assessment, net carbon emissions per unit of electricity are below 10% of the emissions from fossil fuel-based electricity. Only about 6% of the entire population has access to natural gas, primarily in urban areas. Such systems have shorter contact times and therefore are more responsive than updraught gasifiers to surge in gas demands that are experienced when fuelling engines [Fluidized-bed gasification was initially developed to overcome operational problems of fixed bed gasification of fuels with high ash content but is suitable for large capacities (more than 10 MW) in general [A 250 kW rice husk gasifier based power plant has been installed and commissioned in Kapasia, Bangladesh, in October 2007 (Figure The choice of one type of gasifiers over another is dictated by fuel, its final available form, size, moisture content, and ash content. A large amount of cattle dung, Agricultural residue, poultry dropping, water hyacinth, rice husk etc. Approximately 52.54% of the country’s land is used for agricultural practices and 17.50% for forest [The energy content or caloric value of the husks varies somewhat with the crops variety, the amount of bran mixed with the husks, and the moisture content of the husks (usually 8 to 10%). The production of rice husk and rice straw was 10.12 million tons and 25.31 million tons, respectively, in 2011 [Bangladesh, having about 15 sugar mills, produces around 1.68 million tons of bagasse in 2011 which is sufficient to produce power. It is an efficient way to utilize waste biomass and the gas produced from gasification can be used for generating electricity. Increased lighting would also indirectly help the community by increasing the business hours in the market area, improving health conditions, and encouraging new business developments.The authors declare that there is no conflict of interests regarding the publication of this paper.Copyright © 2014 Barun Kumar Das and S. M. Najmul Hoque. According to the report, the energy in 3 kg of husk approximately equals that in 1 kg of fuel oil or 1.5 kg of coal [The typical HHV of agricultural residue ranges between 15 MJ/kg and 17 MJ/kg [According to Bangladesh Bureau of Statistics and Department of Forest, a total of 2.52 million hectares area which is nearly 17.4 percent of the land mass is forests, of which 1.52 million hectares are under direct control of the department. On the other hand, wheat straw, jute stalks, maize residues, lentil straw, and coconut shell are also the promising biomass resources for power generation which counted around 118 MWe. It has been estimated that the total power generation from the agricultural residue is about 1178 MWe. The bagasse has the potential to produce power around 50 MWe which would be able to consume the mills itself and the rest of the power can be supplied to the nearby areas or to the national grid as well. The study also discusses the biomass projects undertaken by the government and non-government organizations, plans and strategies to promote biomass technologies in Bangladesh.We use cookies to help provide and enhance our service and tailor content and ads. Please note that corrections may take a couple of weeks to filter through are available in Bangladesh which is used for power generation. In Bangladesh, agricultural residues vastly meet the household energy demands in rural and semiurban areas. Adequate amount of power generation in a sustainable way is an important issue for rapidly increasing population and economic development. With this configuration, the air or oxidizing agent entering gets in contact with the chars creating the combustion zone. Renewable energy can play an effective role to meet energy demand. However, establishment of bagasse based power plants in sugar industries will lead to an enormous change in the sugar production and the rest of power will be supplied to national grid and to the local communities. With more sophisticated pyrolysis techniques, the volatiles can be collected, and careful choice of the temperature at which the process takes place allows controlling their composition.
