GENERATORS

GENERATOR SETS ARE POWERING TWO KEY BIOGAS PROJECTS IN CHINA

Beijing Yiqing Biomax Green Energy Co., Ltd. is a subsidiary of Beijing Environmental Sanitation Engineering Group Co. It was primarily responsible for the construction and operation of the Dongcun Classified Waste Integrated Treatment

Plant Project in Beijing, and is also a large-scale environmental protection enterprise which uses an anaerobic digestion process to treat domestic waste. The company handles the treatment of kitchen and food waste in Dongcheng District, Xicheng District, Vice

Center and the Yizhuang Development Zone of Beijing. The Dongcun biogas power plant is designed to generate power from the biogas produced from anaerobic fermentation of municipal domestic waste (food waste) and kitchen waste. The plant is equipped with a biogas collection system, biogas storage tanks, biological desulphurization system, biogas de-watering facility and a filtration and pressurization treatment system. Four MWM TCG 2020 V16 biogas generator units (single units with a capacity of 1,560kW) were selected with a total installed capacity of 6,240kW. The whole system is equipped with a biological desulphurization and denitrification system, a waste heat boiler and a biogas generation cogeneration unit. The power produced by the system is then sent to the municipal grid. The MWM gas generator sets are highly efficient at treating complex anaerobic biogases. Power supply method: the plant runs off the power it generates and supplies the surplus power to the grid, maximizing the use of resources. Dongcun Biogas Power Plant is the first anaerobic digestion biogas power plant for kitchen and food waste in Beijing, and the first distributed energy project in

Tongzhou District. The power plant adopts a model whereby biogas is produced from waste, generating electricity, supplying electricity, using electricity for internal equipment, and sending surplus electricity to the grid. This is a highly environmentally friendly strategy, and an energy saving project that can effectively treat waste and achieve resource recycling. It is of great importance

THE CONSTRUCTION AND OPERATION OF THIS PROJECT HAS FILLED THE GAP OF ANAEROBIC DIGESTION BIOGAS POWER GENERATION FOR KITCHEN AND FOOD WASTE IN BEIJING, OPTIMIZING THE ENERGY CONSUMPTION STRUCTURE OF TONGZHOU DISTRICT. THIS HAS CONTRIBUTED TO ENERGY SAVING AND EMISSION REDUCTION EFFORTS. IT HAS ALLEVIATED AN ENERGY ‘BOTTLENECK’ .”

both in terms of environmental benefits and resource utilization. The construction and operation of this project has filled the gap of anaerobic digestion biogas power generation for kitchen and food waste in Beijing, effectively optimizing the energy consumption structure of Tongzhou District. This has contributed to energy saving and emission reduction efforts, is alleviating the energy “bottleneck” constraints of economic and social development, is relieving environmental and ecological pressure, and is transforming the region’s economic growth model. This is consistent with the high-end positioning of Beijing’s sub-centre, and can be used to achieve a coordinated and sustainable development for the city. Around 1,400 kilometers to the North-East lies Mundanjiang City, place of the first landfill gas power generation project in Heilongjiang Province. Mudanjiang Guojiagou Landfill Gas Power Plant is located in an area, where the average temperature in winter reaches below minus 20°C , with a historical extreme of minus 42°C. The annual period in which heating is required can last as long as six months. As the first landfill gas power generation project in Heilongjiang Province, the power plant was established in 2007, and its first phase was connected to the grid in 2009. In its first phase, the plant consumed 840 cubic metres of landfill gas per hour, with an annual consumption of landfill gas reaching approximately 6 million cubic metres, saving about 7,000 tons of standard coal per year. In 2020 the site took part in the landfill stock treatment project in Mudanjiang City. To treat the landfill gas after the stock had been overlaid, Pauway (a distributor of MWM) created a customized MWM TCG 2020 V12 containerized gas generator set with an output of 1.1MW for the second phase of the project according to the customer’s demand. The gas-fired generator set passed the acceptance test of the State Grid in November 2020, and was subsequently officially connected to the grid on 31 December 2020. After the unit was put into operation, the daily power generation capacity of Guojiagou landfill gas power plant reached up to 40,000kWh. Its daily consumption of landfill gas is 38,000m3, and its annual landfill gas consumption is 12,000,000m3, saving around 12,000 tons of standard coal per year. The MWM TCG 2020 gas gensets are custom-tailored to the challenges of a dynamic market setting. The model portfolio offers an output range of 1,000 to 2,000 kWel and is thus perfectly suited to the high demands of a broad application spectrum. The generator sets stand for efficiency, reliability, flexibility and environmental compatibility together with low lifecycle costs and high profitability. For more information please visit:
