JOINT UNDP/WORLD BANK ENERGY SECTOR MANAGEMENT ASSISTANCE PROGRAMME (ESMAP) PURPOSE The Joint UNDP/World Bank Energy Sector Management Assistance Programme (ESMAP) is a special global technical assistance program run by the World Bank's Industry and Energy Department. ESMAP provides advice to governments on sustainable energy development. Established with the support of UNDP and 15 bilateral official donors in 1983, it focuses on policy and institutional reforms designed to promote increased private investment in energy and supply and end-use energy efficiency; natural gas development; and renewable, rural, and household energy. GOVERNANCE AND OPERATIONS ESMAP is governed by a Consultative Group (ESMAP CG), composed of representatives of the UNDP and World Bank, the governments and other institutions providing financial support, and the recipients of ESMAPs assistance. The ESMAP CG is chaired by the World Bank's Vice President, Finance and Private Sector Development, and advised by a Technical Advisory Group (TAG) of independent energy experts that reviews the Programme's strategic agenda, its work program, and other issues. ESMAP is staffed by a cadre of engineers, energy planners, and economists from the Industry and Energy Department of the World Bank. The Director of this Department is also the Manager of ESMAP, responsible for administering the Programme. FUNDING ESMAP is a cooperative effort supported by the World Bank, UNDP and other United Nations agencies, the European Community, Organization of American States (OAS), Latin American Energy Organization (OLADE), and public and private donors from countries including Australia, Belgium, Canada, Denmark, Germany, Finland, France, Iceland, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Sweden, Switzerland, the United Kingdom, and the United States. FURTHER INFORMATION An up-to-date listing of completed ESMAP projects is appended to this report.

Preface This report is the principal output of a technical assistance project in Vietnam executed by the World Bank's Energy Sector Management Assistance Program (ESMAP) and financed by the Swedish International Development Authority (SIDA). The activity pursued recommendations of a previous ESMAP household energy strategy study which are to determine: (i) how the exisiting coal briquette industry can be improved, and (ii) how the current government program for the dissemination of higher efficiency cookstoves can be commercialized. After examining these subjects in detail, the report recommends a five-year pilot program to effectively push tlle market in this direction. The technical assistance activity benefited immensely from the support of the Energy Institute of Vietnam, particularly Dr. Tan Quoc Cuong, Director, Dr. Pham Kanh Toan, Head of International Cooperation and Mr. Nguyen Duy Thong, household energy specialist. Support was also provided by other agencies including the Ministry of Mines, Hanoi Architectural Institute, Vietnam Coal Trading Company, Domestic Coal Company and others. The World Bank/ESMAP team consisted of Ernesto Terrado (task manager), Wolfgang Mostert (economist), Roland Siemons (coal briquette specialist), Keith Openshaw (household energy specialist) and Xiao Ming Song (stoves technologist). The final report was written by Ernesto Terrado from contributions of the team members. TABLE OF CONTENTS PREFACE I.

Scholar, Truba Institute of Engineering & Information Technology, Bhopal (M.P.) India M.Tech. Student, Truba Institute of Engineering & Information Technology, Bhopal (M.P.) India B.Sc. (Biotech), Student, Govt. P.G. College, BHEL, Bhopal (M.P.) India Abstract: Biomass briquettes are a biofuel substitute to coal and charcoal. Briquettes are mostly used in the developing world where cooking fuels are not as easily available. Briquettes are used to heat industrial boilers in order to produce electricity from steam. The briquettes are con-fired with coal in order to create the heat supplied to the boiler. People have been using biomass briquettes since before recorded history. Biomass briquettes are made from agriculture waste and are a replacement for fossils fuels such as oil or coal, and can be used to heat boiler in manufacturing plants. Biomass briquettes are a renewable source of energy and avoid adding fossils carbon to the atmosphere. The extrusion production technology of briquettes is the process of extrusion screw wastes (straw, sunflower husks, buckwheat, etc.) or finely shredded wood waste (sawdust) under high pressure. There is a tremendous scope to bring down the waste of convention energy sources to a considerable level through the development, propagation of non-convention briquettes technology i.e.

  • Determination of Flue Gas Emission Values of Cotton and Sesame Stalk Briquettes
    Tarım Makinaları Bilimi Dergisi (Journal of Agricultural Machinery Science) 2010, 6 (1), 37 - 43 Determination of Flue Gas Emission Values of Cotton and Sesame Stalk Briquettes Sefai BİLGİN Bartın University, Vocational School of Bartın [email protected] Received (Geliş Tarihi): 19.07.2010 Accepted (Kabul Tarihi): 17.08.2010 Abstract: In this study, flue gas emission values of cotton and sesame stalk briquettes which were produced in a conical type briquetting machine were aimed to determine. In order to determine flue gas emission values, the briquettes were burned in a traditional bucket type stove used for household heating. In the study, flue gas emissions such as CO, CO2, SO2, NOx, H2S and O2, flue gas temperature and combustion efficiency were measured by means of flue gas analyzer. At the end of this study, when the combustion process had a steady-state condition, the flue gas emission values measured during burning of the briquettes were found to be very low. When the combustion process had a steady-state condition, the lowest CO emissions were 57 ppm and 160 ppm, average NOx emissions were 196 ppm and 146 ppm, H2S emissions were 37 ppm and 27 ppm, CO2 emissions were 7.92% and 7.41% and O2 emissions were 12.81% and 13.33% for cotton and sesame stalk briquettes, respectively. During the combustion process, cotton and sesame stalk briquettes had no SO2 emission. During the steady-state condition, the average flue gas temperature and combustion efficiency for cotton and sesame stalk briquettes were 400 C and 403 C, 70% and 69%, respectively.

E-mail: [email protected] Received: May 17, 2017 Accepted: July 28, 2017 Online Published: September 29, 2017 doi:10.5539/jsd.v10n5p61 URL: https://doi.org/10.5539/jsd.v10n5p61 Abstract The availability of energy and fuel is always a critical issue, and currently the increasing scarcity and price of kerosene is causing problems for both households and businesses. For example, chicken farmers in Central Kalimantan need to maintain the room temperature when nursing chicks up to 12 days old, and currently have few alternatives to kerosene stoves. Non-carbonized briquettes made from a mix of peat and sawdust can provide an alternative fuel source. The sawdust is available from local sawmills, which is otherwise an unutilized waste product that is burnt off, so adding to local smoke pollution. This study was conducted to determine the optimal composition and manufacturing process to produce bricks that have a maximal calorific content whilst maintaining a long burning time and a reduced tendency to break. Analyses in the laboratory showed that the highest calorific content obtainable was 19 020.63 kJ/kg with a peat/sawdust ratio of 2:1 (20 kg of peat and 10 kg of sawdust).

The tests applied on the orange charcoal powder and on the orange charcoal powder with corn starch (5, 10 and 15 % w/w) were the proximate analysis, the elemental analysis and the determination of the higher heating value HHV) . On the other hand, some tests were carried out on the orange charcoal briquettes, which were the determination of density and the mechanical strength (compressive strength and friability). The results showed that the obtained orange charcoal (OC) has a significant high heating value of 29,000 J/g, and can be used in different processes. When mixed with the binder, its HHV has a small decrease, 27,611 J/g to OC with 5 % of corn starch, 26,857 J/g to OC with 10 % of corn starch and 26,476 J/g to OC with 15 % of corn starch, but still they are considered high values.
