The extensive use of coal-fired boilers is an important cause of serious air pollution. At present, the Beijing municipal government has clearly stipulated that coal-fired boilers should be replaced by oil or gas in major urban areas to reduce the degree of air pollution.

However, the initial investment and operating costs of gas and fuel are very expensive. The development of geothermal resources provides a feasible way to solve this problem. Vigorously advocating and popularizing geothermal heating will make an important contribution to environmental protection.

2, bath health care

Beijing geothermal water belongs to medium-low temperature hot mineral water, which is rich in minerals such as lithium, fluorine, radon, metaboric acid, metasilicic acid, etc., and has certain medical, health care and health preservation functions. Bathing with hot mineral water often has certain curative effect on hypertension, coronary heart disease, cardiovascular and cerebrovascular diseases, rheumatism and dermatosis. Hot mineral water entering the room will undoubtedly greatly improve the quality of life of residents.

3. Entertainment and tourism

Relying on hot spring bath therapy, we can develop a series of entertainment and tourism projects such as swimming pool, water park, recreation center, conference center, convalescent center, hot spring hotel, hot spring resort and high-class hotel.

Extended data:

The formation of hot springs:

One is formed by magmatism in the crust, or accompanied by volcanic eruption. In the dead volcanic terrain where volcanic activity has occurred, the crustal plate movement makes the surface uplift, and there is still uncooled magma underground, which will continuously release a lot of heat energy. Because of the heat concentration of this kind of heat source, as long as there are pores in the nearby water-bearing rocks, they will not only be heated into high-temperature hot water, but also boil into steam, mostly sulfate springs.

The second is formed by the infiltration and circulation of surface water. That is to say, when the rain drops to the surface, it penetrates downward and goes deep into the aquifer in the earth's crust, forming groundwater. Groundwater is heated by geothermal energy below to become hot water, and deep hot water mostly contains gas, mainly carbon dioxide. When the temperature of hot water rises, if there is a dense impermeable rock above it to block the way, the pressure will be higher and higher, so that hot water and steam are in a high pressure state, and as long as there are cracks, they will rush up.
