Which city is the geothermal heating smokeless city?

The smokeless city of geothermal heating is xiong'an new area.

Since 2009, xiong'an new area began to use geothermal energy for central heating on a large scale, and now geothermal energy heating has covered more than 95% of the buildings in the county, making it a "smoke-free city". The indirect heat exchange technology is adopted to promote the development and utilization of geothermal resources and make geothermal energy a new force for clean heating in winter. It not only brings comfort and convenience to local residents, but also provides experience for the development and utilization of clean energy in China.

The technical highlight of "Xiongxian Model" is to adopt the process of "indirect heat exchange" to realize "taking heat without taking water", that is, after the geothermal water is pumped out, the heat is taken through the heat exchanger, and then the cold water is re-injected into the groundwater layer by the recharge well. At the same time, another circulating system sends the heated water to thousands of households through heating pipes, achieving the effect of "balance between mining and irrigation" and making geothermal energy a new force for local clean heating in winter.

geothermal resource

Geothermal resources refer to geothermal energy, geothermal fluid and their useful components that can be developed and utilized in the earth's crust, and are a renewable and clean energy source. Xiongxian County in Hebei Province is known as the "hometown of hot springs", and its geothermal resources development began in the 1970s. However, due to the lack of unified planning and effective management, local resources have been exploited and utilized in a predatory manner, resulting in serious waste of geothermal resources and secondary pollution of the surface environment.

Geothermal energy is a stable, reliable, green and low-carbon renewable energy, which is not affected by natural conditions such as weather, and the average energy utilization rate is much higher than that of solar energy and wind energy. Geothermal energy resources are buried underground 1500m ~ 2500m, which has the characteristics of large reserves, wide distribution, cleanliness and environmental protection, and can be used in many fields such as power generation and heating.
