RT Journal Article ID 2c0857267a33cbc9 A1 Dyad'kin, Yu. D. T1 Problems of Geothermal Technology JF Heat Transfer Research JO HTR YR 1999 FD 1999-06-01 VO 30 IS 4-6 SP 289 OP 295 AB Natural, ecological, and economic conditions of the use of various systems of the production of geothermal energy are considered using economic-and-mathematical modeling of eight main types of geothermal production processes. The efficiency of geothermal circulation systems is corroborated. The schematic diagrams, the preliminary evaluations, and the prospects of new technologies of the joint development of geothermal and fuel resources to produce power-generating (with the parameters 550°C and 25 MPa) or process (140−160°C) steam are given.
