    May 21,  · The Krafla area is named after one of the mountains at the centre of the region and is the location of the Krafla geothermal power plant, which pumps cold water into the ground and uses the rising steam to make electricity. At Krafla Power Station, high- and lowpressure steam from 18 boreholes drives two 30 MW turbines. Built by the Icelandic government, Krafla came under the ownership of Landsvirkjun in Construction began with trial boreholes in , the first turbine unit started up in August , and regular operations began in February

The Krafla geothermal power plant is a geothermal power generating facility located in Iceland, close to the Krafla Volcano and the lake Mývatn. It is considered to be Iceland's largest power station with its 33 boreholes, and it is able to produce GWh of electricity annually with its installed capacity of 60 MW (2 x 30 megawatts).Country: Iceland.

@article{osti_, title = {SVARTSENGI FIELD PRODUCTION DATA AND DEPLETION ANALYSIS}, author = {Gudmundsson, J.S. and Thorhallsson, O.S.}, abstractNote = {There have been two major high-temperature geothermal field developments in Iceland in the last decade; Krafla in the north-east, and Svartsengi in the south-west.

These and other geothermal developments have recently been reported Cited by: 4. Krafla geothermal power station. Local sightseeing and tourism Krafla‘s location near Lake Myvatn makes it an ideal stopping place for travelers in north Iceland.

Just above the station is a popular hiking area including the recent lava field around "Leirhnjukur" and the explosion crater "Viti" (Hell), both popular sightseeing attractions.

Information about Krafla Wikimedia, Creative Commons, Photo Credit: Earthquakes Krafla. Krafla is a caldera, part of a greater volcanic system of the same name, located north of Lake Mývatn in North Iceland.

It is one of the country’s most explosive volcanoes, having gone off approximately 29 times since the country was first settled. This paper deals with the Krafla geothermal field, northeastern Iceland, and illustrates how the upgrade of high enthalpy geothermal plants can be effective and lead to increased power production.

The aim of this paper is to examine ways of improving the thermodynamic performance of the power plant at Krafla in light of the recent fdn2018.com: G. Langella, V. Paoletti, R. DiPippo, A.

The Iceland Deep Drilling Project Well 1 was designed as a 4- to 5-km-deep exploration well with the goal of intercepting supercritical hydrothermal fluids in the Krafla geothermal field, Iceland.

The well unexpectedly drilled into a high-silica ( % SiO2) rhyolite melt at approximately km. Some of the melt vesiculated while extruding into the drill hole, but most of the recovered. The approach to Krafla is part of the beauty of the area.

The gigantic pipes of the Geothermal Power Station, Kröflustöð, flank the road and create a bizarre gateway which welcomes you in this evocative realm, while all around plumes of steam placidly rise from the silver chimney over the desolate ground.
