Summary
China's largest non-interference geothermal heating system has been activated at the Western China Science & Technology Innovation Harbor in Fengxi New City, Xixian New Area, Shaanxi Province.
Recently, China’s largest non-interference geothermal heating system has been activated at the Western China Science & Technology Innovation Harbor in Fengxi New City, Xixian New Area, Shaanxi Province, according to the Party Committee of Fengxi New City. Six of these integrated energy supply stations will be providing heating, cooling and hot water for buildings totalling 1.59 million square meters so as to meet the energy needs of Xi’an Jiaotong University’s 25,000 researchers and 10,000 faculty members in the Innovation Harbor.
It is understood that the project utilizes non-interference geothermal heating technology and medium-deep geothermal energy to provide a clean heat source. Using metal conduit and a heat exchange medium, heat (but not water) is taken from deep underground (2 to 3 kilometers in depth) where there are stores of geothermal energy at a temperature of 70 degrees centigrade to 120 degrees centigrade.
The project, compared with conventional coal-fired boilers, turning to this technology for heating can, in one heating period during a year, reduces carbon dioxide emissions by 68,000 tons and other emissions such as sulfur dioxide and nitrogen oxide by 850 tons, which is equivalent to 25,400 tons of standard coal.
