Generating electricity by thermoelectricity is a kind of efficient mode using terrestrial heat solar energy, oceanic energy, surplus heat or deposed heat, which can convert the low potential energy into electricity.
Geothermal energy power development in New Zealand first began in the mid 1950s, and there is thepotential for the supply of up to ten per cent of the country's power needs.
Low temperature heat cable, source of which is electricity, has widely application and development in the heating system worldwide, which can avoid the disadvantages from traditional heating.
The work in this paper develops of low temperature radiation heating cable, analyses thermal field under application environment, and affords theoretic basic for making the cable in our country.
Combined with the sedimentary burial history and basin geothermal history, the modeling of carbon isotope kinetics provides a new and effective means for the determination of the origin and accumulation history of natural gas pools.
The carbon isotopic characteristics of natural gas are not only affected by the gas source and maturity of the source rock, but also are related to the accumulation condition and geothermal gradient in a basin.
Several natural associations composed of thermophilic anaerobic bacteria capable of utilizing various cellulose materials at 60 ± 2°C and pH 6.0-7.0 were isolated from the sludge of Kamchatka geothermal springs.
Temperature is an important factor affecting seismic velocity, and terrestrial heat flow is the most direct indication of temperature distribution of the lithosphere.
It has higher resolution and greater depth penetration than the direct current method and is especially fit for geothermal energy exploration and low-and mid-level groundwater detection.
The nine metallic materials have been hung in geothermal water and corrosivepotential,polarizing curve and polarizing resistance have been measured.Thecorrosion under this condition maybe prevented by RTF coating.
The U. S. energy scenario, at the present time is highly complex. The U. S. had become to a great extent,dependent on oil and gas and has not as yet turned over to the more abundant coal and uranium. However, the present administration is trying to remove many of the restrictions, to encourage the development and exploitation of all possible domestic resources including coal, nuclear energy, oil, gas, shale, geothermal and renewable energy and to encourage the use of coal.
This article gives a brief description of the Model D3-1.7/0.5 experimental geother-mal steam turbine unit developed by Qiangdao Steam Turbine Works. Two units of this type have been in operation in Yangbajing experimental geothermal power station and the third one is now under installation. Design considerations for the thermody-namic system, plant layout, steam turbine proper, the oil system for governing and safety control, butterfly valves and some major auxiliary equipment are given. The article conclu...
