| China's first chicken manure-biogas plant GE Energy's ecomagination-certified Jenbacher gas engines will use biogas created from chicken manure to generate needed power and heat at a large chicken farm north of the China's capital city of Beijing. The plant is the first of its type in China and could pave the way for similar applications in the future. With commercial start-up of the Beijing Deqingyuan Chicken Farm Waste Utilization plant, the project comes as the country seeks innovative ways to meet its energy and environmental requirements. Providing 14,600 MWh of electricity per year, the project is designed to help reduce sub-urban electricity shortages. By using the biogas for power generation in place of previously used coal-fired power, the new project is expected to reduce the equivalent of about 95,000 tons of CO2 per year, qualifying the project for the U.N.-sanctioned Clean Development Mechanism (CDM) program. The Beijing Deqingyuan project is also reducing the farm's dust levels, further enhancing the area's air and water quality by controlling odors and improving the work environment for the farm's employees. Located in YanQing District, about 50 kilometers north of Beijing, the farm owns three million chickens, producing 220 tons of manure and 170 tons of wastewater each day. The farm's new cogeneration system features an anaerobic digester system to treat the waste material, producing enough biogas to fuel two GE's Jenbacher JMS 320 GS-B.L gas engines. The plant has an installed electric capacity of more than 2 MW for use at the chicken farm. Additionally, the plant's thermal output is used to support the chicken waste fermentation process and also heat the chicken farm in the winter. "This biogas project will quickly pay for itself by meeting the customer's demand for cost-effective electricity and heat," said Jack Wen, president and CEO of GE Energy China. "We estimate that the customer will save more than US$1.2 million a year in electricity costs alone." write your comments about the article :: © 2008 Construction News :: home page |
