Recently, with the completion and operation of the last geothermal well, the first medium and deep geothermal heating project in Jilin Province - Da'an medium and deep geothermal heating demonstration project, all 8 geothermal wells have been put into heating operation.
Now, the room temperature in our home can reach 23 to 27, which is cleaner and warmer than when we used to burn coal for heating!Sun Dongmei, a resident of Dagangzi Town, Da'an City, Baicheng City, Jilin Province, said.
The project is the first geothermal heating project of the Three Gorges Corporation, which is invested and constructed by China Three Gorges New Energy (Group) Co., Ltd., a subsidiary of the Three Gorges Corporation. Through the clean heating technology of "taking heat without water", the project uses 8 coaxial geothermal wells as the heat source system and 1 surface heat exchange station to provide heating services for 4,512 households in Dagangzi Town, with a total heating area of 150,000 square meters. Compared with traditional coal-fired boilers, a heating season can save about 3,822 tons of standard coal and reduce carbon dioxide emissions by about 9,388 tons, with significant environmental benefits.
The project is a demonstration project for medium and deep geothermal heating in China's high-latitude areas, which paves a new way for clean winter heating in towns and towns in high-latitude areas, accumulates valuable experience for the development and construction of subsequent geothermal heating projects, and helps the comprehensive green transformation and development of the economy and society in Northeast China.
