Improve operational efficiency of heating systems and utilization of combined heat and power, reducing 300,000 tons of coal consumption and 500,000 to 550,000 tons of CO2 emission annually
Harbin, China, January 31, 2007 - ABB, the leading power and automation technology group, announced today that the Harbin Daoli district heating project supported by ABB’s technology and a Danish loan has been completed. As the biggest district heating infrastructure construction project in Harbin, this project helps reduce greenhouse gases by cutting energy loses and carbon dioxide emissions and improving operational efficiency of heating systems. Meanwhile, ABB automation control technology also enables one million local residents to enjoy comfortable room temperature above 18°C, even when the average temperature is -21 °C.
Daoli is one of the seven districts of Harbin. In the heating project, ABB uses the hot water produced from Harbin Hua Neng District Heating Co. Ltd. as primary heating resource. Water from the pre-insulated underground pipes is transferred to 156 self-operating heating exchangers units instead of the traditional boiler room and then directly fed into residential radiator installation, covering an area of 17.58 million square meters. With ABB’s advanced automation technology, the temperature and the flow velocity of the water is regulated automatically based on the actual consumer heat consumption and the outdoor temperature so as to provide comfortable room temperatures, save energy and protect the environment.
Senior Vice President of ABB China Bernd Muehe stated at the project completion ceremony, “we are very proud of participating in China’s biggest district heating project. ABB’s world leading district heating technology is characterized by energy-efficiency, low noise, flexible control and customization. It could help our customer in the ‘Ice City’ of Harbin to raise the utilization of combined cycle energy production and improve the operational efficiency of heating systems as well as reduce the consumption of coal and emission of greenhouse gases considerably.”
At the end of October, 2004, ABB succeeded in winning the US$ 40 million main contract of Daoli district heating project. Under the contract, ABB provided 96.1 km of pre-insulated pipes, 378 frequency converters, 252 secondary network circulation pumps, 126 secondary network pressure holding pumps, 252 Heat Exchangers, 2000 instruments that are used to supervise and control the network and substations, as well as one Saturn SCADA system with more than 10,000 signals. ABB also helped the customer rebuild 42 turnkey substations and include them in the SCADA system.
All substations are autonomously controlling the temperature and flow at each substation, freeing stokers from low-end intensive labor work. The operation center equipped with ABB Saturn SCADA system is used to monitor and if needed to control the operation of the 168 heat exchangers units.
ABB also provided integrated technical training to the stokers and engineers from Hua Neng District Heating Co. Ltd, enabling the customer to deal smoothly with the daily operation and maintenance of all of the products and systems, helping them raise the consciousness of protecting their investment and extend the lifecycle of the equipment.
Throughout the implementation period, intensive contacts have been maintained with the city, its local government, the district heating utility, design offices and involved parties. ABB and the Danish District Heating Export Organization also jointly held two symposiums, discussing how to save energy and evaluate the life cycle costs by adopting new design principles and ideas.
Mr. Chen Yuwei, Project Manager from Harbin HuaNeng District Heating Co. Ltd said proudly, “When all consumers are connected, we can save 300,000 tons of standard coal annually, reduce emission of 2,200 tons of SO2, more than 500,000 tons of CO2 and 11,000 tons of dust. Inhabitants in Daoli District could enjoy cleaner and greener living environment besides more comfortable heating service.”
Reduction in the CO2 emission is part of a CDM (Clean Development Mechanism) contract between the Danish Government and China, under the Kyoto Protocol from December 1997. According to this agreement, the Danish Government is buying the CO2 reduction (so called CER’s or Certified Emission Reductions) from the HuaNeng District Heating Co. for a period of ten years. The market price is at the moment around 10 USD per certified ton CO2 emission reduction.
ABB has more than 25 years of experience in delivering district-heating projects worldwide. Its leading products and systems have been widely deployed in more than 200 projects and cities throughout the world, including TianJin, Xi’an, HouMa in Shanxi, Zunua in Hebei and Hihezi in Xinjiang (all supported by Danish Government Loan) as well as many other cities in China and Central Asia.
