Demonstration Project Biogas Power Generation from Agricultural and Herding Waste

Abstract The project belongs to the competitive grants sub-activities of the priority demonstration projects at the provincial level. After the project put into operation, the first phase project will produce daily about 10,000 cubic meters of biogas with the installed capacity of 1MW, daily power generation of 20,000 kWh, annual power generation of 7.5 million kWh, daily production of 8 tons of solid organic fertilizer, and daily production of 200 tons of liquid organic fertilizer. At the same time, the annual methane emission reduction can reach nearly 0.9 million cubic meters equivalent to reducing CO2 emissions of 3,240 tons / year.

6 Renewable Energy, 6.5 Biogas

Biogas Handbook

Abstract In line with the ever increasing price of energy, biomass energy sources such as biogas have entered a new phase of development. Household biogas technology has enjoyed a period of rapid development, and the technology is continuing to mature, with more varieties and models developing, and the field of use becoming ever wider. In order to assist more peasants to easily choose an appropriate digester, this book has been written as a reference to aid the comprehensive use of biogas and its digesters. This book features a systematic and detailed explanation of the types and application environments of digesters, construction and commissioning of digesters, use and management of biogas, and the comprehensive holistic use of gas. This book is designed for farmers and friends interested in using biogas.

Rural Biomass Energy 2020 in the People’s Republic of China

Abstract This publication explores the potential of biomass energy to close the urban-rural energy gap, raise farmer incomes, and address some of the environmental concerns in the People’s Republic of China (PRC). Its findings are useful for other developing and medium-income countries currently in the process of drawing up their respective energy-for-all strategies. The report examines the promises and limitations of leading biomass energy technologies and resources for various distribution scales, including but not limited to household biogas digesters. The information is based on lessons learned and experiences from the ADB-financed Efficient Utilization of Agricultural Wastes Project in the PRC, as well as findings and conclusions from a technical assistance grant to assist the government draft a national strategy for developing rural biomass energy.

Biofuels in the Greater Mekong Subregion

Abstract In the Greater Mekong Subregion (GMS), a growing demand for biofuels could help support the agriculture sector and provide an alternative source of energy. However, if deployed unsustainably, biofuels development can be associated with numerous risks that have negative ramifications for human development. This paper reviews existing literature and integrates various themes to provide an overview of four main issues related to biofuels deployment in the GMS: the need for alternative energy, risks to food security, considerations for environmental management, and opportunities for rural development. This paper was prepared as a discussion piece for the GMS 2020 International Conference (20–21 February 2012 in Bangkok, Thailand).

Completed Equipment Development of Power Generation by Circulating Fluid Bed Straw Gasification

Abstract It is one of the sub-grant projects in the second round of state-level biomass competitive activities. The project aims to design a large and complete biomass circulating fluidized bed pyrolysis process system, including the biomass pyrolysis device, gas purification system, waste heat recovery system and flue gas purification system to carry out the demonstration construction, through improving the existing technologies. The pyrolysis process of fluidized bed is working at high temperature, uniformly and stably. While the straw pyrolysis gas is used for generating power, it cracks tar, which improves the straw utilization efficiency and gas quality. The technical support unit is the Department of Thermal Engineering of Tsinghua University, and the equipment manufacturing unit is the Tangshan Xinde Boiler Group Co., Ltd. The project is currently underway.

Development of Briquetting Machine Model BCYK

Abstract It is one of the sub-grant projects in the second round of of National Biomass competitive grant activities. It is planed that the project develops the biomass briquetting molding prototype with low energy consumption at normal tempreture, through reasearching the two core technologies of the formation of power transmission and molding module. The prototype changes the traditional “compression molding with positive pressure at high temperature ” to “grind molding with partial tensor at normal temperature”, which solves the problems of “poor force conductivity” and “high moisture” of the biomass raw materials of straw type from the mechanism, and reduces the pressure and energy consumption needed by molding radically. The molding machines improve effectively the stability of the equipment and extend the working life of the core components. The project is currently underway.
