Kawerau Power Station
The Kawerau Power Station is a 100-megawatt geothermal power plant located just outside the town of Kawerau in the Bay of Plenty Region of New Zealand. The power station is situated within the Kawerau geothermal field, which is part of the Taupo Volcanic Zone. Completed in July 2008 by Mighty River Power at a cost of NZ$300 million, the plant's capacity proved greater than expected. The station is the largest single generator geothermal plant in New Zealand. Energy production The Kawerau geothermal power station boosted the country's geothermal capacity by 25 percent and significantly increased local generation capacity in the Eastern Bay of Plenty. The plant meets approximately one third of residential and industrial demand in the region and provides cost certainty to local industry including Norske Skog Tasman. The station uses a single Fuji turbine and steam from geothermal bores. The two phase fluid is flashed/separated twice to produce high and low pressure steam to fee ...

Bay Of Plenty Region
The Bay of Plenty ( mi, Te Moana-a-Toi) is a region of New Zealand, situated around a bight of the same name in the northern coast of the North Island. The bight stretches 260 km from the Coromandel Peninsula in the west to Cape Runaway in the east. The Bay of Plenty Region, governed by the Bay of Plenty Regional Council, incorporates several large islands in the bay, in addition to the mainland area. Called ''Te Moana-a-Toi'' (the Sea of Toi) in the Māori language after Toi, an early ancestor, the name 'Bay of Plenty' was bestowed by James Cook in 1769 when he noticed the abundant food supplies at several Māori villages there, in stark contrast to observations he had made earlier in Poverty Bay. History According to local Māori traditions, the Bay of Plenty was the landing point of several migration canoes that brought Māori settlers to New Zealand. These include the ''Mātaatua'', ''Nukutere'', ''Tākitimu'', '' Arawa'' and ''Tainui'' canoes. Many of the desce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geothermal Power Plant
Geothermal power is electrical power generated from geothermal energy. Technologies in use include dry steam power stations, flash steam power stations and binary cycle power stations. Geothermal electricity generation is currently used in 26 countries,Geothermal Energy AssociationGeothermal Energy: International Market Update May 2010, p. 4-6. while geothermal heating is in use in 70 countries. As of 2019, worldwide geothermal power capacity amounts to 15.4 gigawatts (GW), of which 23.9 percent or 3.68 GW are installed in the United States. International markets grew at an average annual rate of 5 percent over the three years to 2015, and global geothermal power capacity is expected to reach 14.5–17.6 GW by 2020. Based on current geologic knowledge and technology the Geothermal Energy Association (GEA) publicly discloses, the GEA estimates that only 6.9 percent of total global potential has been tapped so far, while the IPCC reported geothermal power potential to be in ...

Kawerau
Kawerau is a town in the Bay of Plenty region of the North Island of New Zealand. It is situated 100 km south-east of Tauranga and 58 km east of Rotorua. It is the seat of the Kawerau District Council, and the only town in Kawerau District. Kawerau is a small community, with an economy that is largely driven by the nearby pulp and paper mill that is run by Norske Skog and OJI Fibre Solutions. It is located along State Highway 34, southwest of Onepu, and is the terminus of the East Coast Main Trunk Railway, and the commencing point of the Murupara Branch railway. Kawerau was one of the worst-affected towns in the 1987 Edgecumbe earthquake. History and culture European settlement Kawerau, one of the youngest towns in New Zealand, was founded in 1953 as a mill town for the new Tasman pulp and paper mill. The site for the mill was chosen because of the ready availability of geothermal energy, water from the Tarawera River and the large supply of pine timber from the ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

The New Zealand Herald
''The New Zealand Herald'' is a daily newspaper published in Auckland, New Zealand, owned by New Zealand Media and Entertainment, and considered a newspaper of record for New Zealand. It has the largest newspaper circulation of all newspapers in New Zealand, peaking at over 200,000 copies in 2006, although circulation of the daily ''Herald'' had declined to 100,073 copies on average by September 2019. Its main circulation area is the Auckland region. It is also delivered to much of the upper North Island including Northland, Waikato and King Country. History ''The New Zealand Herald'' was founded by William Chisholm Wilson, and first published on 13 November 1863. Wilson had been a partner with John Williamson in the ''New Zealander'', but left to start a rival daily newspaper as he saw a business opportunity with Auckland's rapidly growing population. He had also split with Williamson because Wilson supported the war against the Māori (which the ''Herald'' termed "the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Herald Tribune
The ''International Herald Tribune'' (''IHT'') was a daily English-language newspaper published in Paris, France for international English-speaking readers. It had the aim of becoming "the world's first global newspaper" and could fairly be said to have met that goal. It published under the name ''International Herald Tribune'' from 1967 to 2013. Early years In 1887, James Gordon Bennett Jr. created a Paris edition of his newspaper the '' New York Herald''. He called it the ''Paris Herald''. When Bennett Jr. died, the paper came under the control of Frank Munsey, who bought it along with its parent. In 1924, Munsey sold the paper to the family of Ogden Reid, owners of the ''New-York Tribune'', creating the '' New York Herald Tribune'', while the Paris edition became the ''Paris Herald Tribune''. By 1967, the paper was owned jointly by Whitney Communications, ''The Washington Post'' and ''The New York Times'', and became known as the ''International Herald Tribune'', or ''IHT'' ...

Norske Skog Tasman
The Tasman Mill site is a pulp and paper mill located on Fletcher Avenue just outside the town of Kawerau in New Zealand. The Tasman Mill site is the largest single employer in the Eastern Bay of Plenty region. Three pulp or paper companies previously operated in Kawerau: Norske Skog operated the mechanical pulp mill and newsprint paper mill; Oji Fibre Solutions, formerly Carter Holt Harvey, operated the kraft pulp mill; and SCA (now Essity) who manufacture tissue and base paper (physically separate mill on Fletcher Avenue). The Tasman Pulp and Paper Mill has been a source of controversy due to the discharging of waste into the Tarawera River. Despite protests from locals (including local Iwi), resource consent was renewed in 2009 to allow for discharge into the river for the next 25 years. The workforce at the Tasman Mill declined from its peak in the 1980s. The Norske Skog Tasman mill that produced newsprint was closed in June 2021, with the loss of 160 jobs. The main produc ...

Two-phase Flow
In fluid mechanics, two-phase flow is a flow of gas and liquid — a particular example of multiphase flow. Two-phase flow can occur in various forms, such as flows transitioning from pure liquid to vapor as a result of external heating, separated flows, and dispersed two-phase flows where one phase is present in the form of particles, droplets, or bubbles in a continuous carrier phase (i.e. gas or liquid). Categorization The widely accepted method to categorize two-phase flows is to consider the velocity of each phase as if there is not other phases available. The parameter is a hypothetical concept called Superficial velocity. Examples and applications Historically, probably the most commonly studied cases of two-phase flow are in large-scale power systems. Coal and gas-fired power stations used very large boilers to produce steam for use in turbines. In such cases, pressurised water is passed through heated pipes and it changes to steam as it moves through the pipe. The d ...
