Beijing Plain Shallow Geothermal Exploration Results Can Be An International Leader

April 28 from Beijing Geological Prospecting Bureau

, the international launch of the first investigation and assessment of shallow geothermal energy work that Beijing Plain Shallow geothermal energy resource potential of 662 million tons of standard coal equivalent, may be heating area of 959 million square meters. According to the plan, Beijing "during" the use of shallow geothermal energy construction area is expected to reach 35 million square meters, will save 36,000 tons of standard coal annually and reduce emissions of 840,000 tons of carbon dioxide to reduce emissions of 10,000 tons of sulfur dioxide is about reduce dust about 1.3 million tons, reducing 03,900 tons of nitrogen oxide emissions.

It is understood that officers took three years of geological exploration survey in Beijing plain area 6400 square kilometers within the 15-150 m depth of the shallow geothermal energy resources and distribution of the characteristics and conducted Ground Source Heat Pump Appropriate zoning, middle of this month, "Beijing Plain Shallow geothermal energy resources, geological survey report" through expert assessment, the overall results achieved international advanced level.

Shallow geothermal energy is embedded in the shallow crust layer, temperature range of less certain depth (usually less than 200 meters) of rock and soil and groundwater, in the current technical conditions, with the development of value in low temperature geothermal resources. It is with deep geothermal energy Solar Energy The product of joint action, both clean Energy , Is renewable energy, natural and artificial recharge through or winter and summer temperature using a reverse two seasons remained after the geothermal field of dynamic equilibrium, which in the long term recycling.

According to the geological survey in Beijing, Deputy Secretary, Health shun the project leader introduced the basis of geological, hydrogeological, economic and technological conditions on the shallow geothermal energy resources development and utilization of appropriate methods, the project team divided the water ground source Heat Pump And Geothermal ground source heat built-up areas and further divided into suitable areas, more appropriate for the area, more appropriate, and ban the construction area. Among them, the ground source heat pump suitable areas and more appropriate for the total area of 1345 square kilometers; Geothermal ground source heat pump suitable areas and more appropriate for the total area of 3496 square km.

"Project team preliminary analysis of the plain area of Beijing from 3 to 150 m of shallow geothermal energy resource potential, the results show that the plain area of Beijing shallow ground temperature to the static reserves 1.9 1015 kJ, equivalent to 662 million tons of standard coal, heating area can be 959 million square meters, which can meet the overall planning of Beijing in 2020, the total heating area of the request. "Wei shun said that based on the Survey, the project team selected 30 typical Project Statistical analysis, and conventional heating boilers and water chillers project compared the use of shallow geothermal energy in winter heating energy consumption can be Energy More than 30%, 10% energy savings over summer.

According to reports, Beijing is China's exploitation of shallow geothermal energy earlier cities. As of the end of 2008, the city has more than 500 projects, 13 million square meters of buildings using shallow geothermal energy heating and cooling, these projects are located in different parts of Beijing, both suitable for Water Source Heat Pump The region is also suitable for areas of ground source heat pump, in which Sinopec Management Institute of ground source heat pump system is the currently the largest ground source heat pump to run Engineering, Beijing Friendship Hospital project is the largest coal-fired boiler to water heat pump heating projects.
