The Key Technical Analysis on the Hot Dry Rock in Northeast Cold in China

Abstract:

Article Preview

Northeast heat supply is an eternal demand, it would cost tens of thousand of moneys for heat supply, on the other hand, the resource of coal and fossil fuels is non-renewable source of energy, in the future it will be consumed, so it is still a serious problem to solve the winter heat supply. At the same time, the hot dry rock has three essential factors including a huge number, renewable and not polluting the environment, which will open up new ways on heat supply in cold area. Based on its advantages the paper will design a heated system more effective than the technology of shallow ground source heat pump, meanwhile analysis the key technology during exploiting the hot dry rock progress, then the thermal conductivity of rock under high temperature and high pressure and the heat transfer ability between rock and water as well as pipe material and insulation technology, all of which will realize the key technology about the dry-heat rock heating. In conclusion, if the key technology on heated system would be settled, it will bring breakthrough about using the hot dry rock on heated supply in cold areas.
