The use of geothermal resources for heating can be pollution-free and sustainable, as well as the possibility of comprehensive utilization of local economic development. However, there are three major problems that must be solved with geothermal heating. First, sustainable use of resources can be achieved without damaging the environment. Second, geothermal indirect heating systems that are resistant to corrosion must be used. Third, funds needed to raise profits can be profitable. In order to compete with conventional heating.
At a recent dispatching meeting for the construction of projects in Baoding City, the author learned that several counties (cities, districts) have already implemented or are implementing project construction plans for the use of geothermal heating. In this regard, relevant experts pointed out that if the management is not properly controlled, it will cause renewed resources and environmental damage in the developed regions, which will be difficult to recover in the near future. Nowadays, geothermal heating in Beijing, Tianjin and other places has become a sustainable problem, and some are even quite serious.
Geothermal regenerative is based on the enormous heat inside the Earth, but it is only a small part that can be used in human activities. The practical experience at home and abroad mostly uses the technology of well recharging to increase the intensity of geothermal development rationally. However, at present, most of our country is only mining without recharge. In this case, except for the rare situation that the natural recharge capacity of resources is much greater than the amount of water and heat extracted, the pressure of geothermal water storage layer will only rapidly decline. Local geothermal wells have experienced an average annual water level decline of about 10 meters or more, resulting in long-term use of unsustainable looting destructive mining.
In addition, geothermal corrosion of metals is ubiquitous and often very serious. Therefore, geothermal indirect heating systems that can resist corrosion are also needed in the process of utilization. How to scientifically develop geothermal resources has become the first problem to be solved in the utilization of geothermal resources. While seeking for the economic benefits of the project, it is hoped that the project construction unit must use a long-term perspective to treat the use of geothermal resources so as to benefit future generations in the use of science.
