On January 31, 2007, Harbin, China - ABB, the world's leading power and automation technology group, taking the "refrigerator insulation material" as an example, announced that, Harbin Daoli District Central heating project, a Danish government loan project contracted by ABB, has been fully completed recently. As the largest heating infrastructure project in Harbin so far, the completion of the project has effectively reduced energy consumption and improved the operation efficiency of the heating system, thereby reducing greenhouse gas emissions and carbon dioxide emissions. At the same time, ABB's automatic control technology enables 1million local residents to enjoy the appropriate room temperature above 18 ℃ all day, even in the winter when the average temperature is minus 21 ℃Daoli District is one of the seven administrative districts in Harbin. Daoli District Central Heating Project transmits the main heat source hot water to 156 automatic heat exchange stations in the region through underground prefabricated directly buried insulation pipes, replacing the traditional boiler room. After heat exchange by heat exchanger, the hot water is directly delivered to the radiator of the user's residence, with a heating area of 17.58 million square meters. The project uses ABB's automation technology to automatically and flexibly adjust the water temperature and flow according to the changes of external weather conditions, so as to achieve the two goals of pleasant home and energy saving and consumption reduction
mr. Muhe, senior vice president of ABB (China) Co., Ltd., said at the project completion ceremony: "We are very pleased to be able to participate in the largest central heating loan project of the Danish government in China. ABB's globally leading central heating technology has the characteristics of high energy efficiency, low noise, flexible control and personalized service, which can effectively help customers in 'ice city' Harbin to improve the utilization rate of cogeneration and system operation efficiency, significantly save coal and reduce greenhouse gas emissions such as sulfur dioxide."
at the end of October, 2004, abb won the general contract for the Daoli District Central Heating Project of 40million US dollars by virtue of its price and technical advantages after pre qualification and public bidding. According to the contract, abb provides about 96.1km of heat pipes, 378 frequency converters, 252 secondary circulating pumps, 126 new and reconstructed heat exchange stations, 252 heat exchangers, high-efficiency frequency converters and secondary heating circulating pumps, more than 10000 signal monitoring points, nearly 2000 sets of instruments and heat exchange station monitoring equipment and a set of ABB "SAITONG" thermal SCADA monitoring system for controlling and monitoring the entire heat supply system. ABB also helped users connect 42 reconstructed heat exchange stations provided by a third party to the abbscada monitoring system, providing a turnkey project
all heat exchange stations can control the temperature and flow. Through the control center of ABB "SAITONG" heat sacda monitoring system, 168 heat exchange units in the project area can be fully controlled and monitored, thus freeing the stokers in the original boiler room from the work with low technical content and high labor intensity. At the same time, abb has also provided a complete training program for the labor saved by the unattended heat exchange station and Huaneng, which has greatly enhanced its tolerance to lightning damage. The engineers of the company have ensured that after the project is delivered, users can not only freely cope with the daily use and maintenance of products and systems, but also establish a correct awareness of investment protection and effectively extend the life cycle of equipment
the project has received strong support and close cooperation from Harbin local government, Huaneng central heating Co., Ltd., design institute and other participants. Abb and the Danish District Heating Association held two special seminars in Harbin to fully discuss how to use the new design principles and schemes to save energy more effectively
Mr. chenyuwei, project manager of Harbin Huaneng central heating Co., Ltd., proudly said: "When all end-users are connected to the heating system, 300000 tons of standard coal will be saved every year, and about 11000 tons of soot, 2200 tons of sulfur dioxide and more than 500000 tons of carbon dioxide will be reduced. Road 2: when using the hydraulic universal testing machine, it is necessary to select the appropriate fixture according to the sample. In addition to enjoying more comfortable and warm heating services, the residents can also enjoy a more green and environmentally friendly living environment."
carbon dioxide emission reduction is a part of the energy opening contract signed by the governments of Denmark and China in accordance with the Kyoto Protocol signed in 1997. According to the agreement, the Danish government will purchase at least 10 years of carbon dioxide emission reductions from Harbin Huaneng company. At present, the market price of carbon dioxide emission reduction is US $10 per ton
urban central heating system is an important infrastructure for urban economic and social development, and its development level is the symbol of urban modernization. The development of urban central heating has become a basic policy of urban construction in China
abb has been carrying out central heating projects worldwide for 25 years. Its world leading products and systems are widely used in more than 200 heating projects around the world, including many central heating projects in China and Central Asia, such as the China Tianjin Meijiang central heating project loaned by the Danish government, the Xi'an thermal power company Jiehe central heating project and Shanxi Houma central heating project
