Polk Power Station Expansion, Florida, United States of America
Electric's Polk Power Station is further extended to change over four existing basic cycle ignition turbine units into an incorporated joined cycle unit. The development will build the station's producing limit by an extra 460MW.
Development deals with the extension began in January 2014 and are booked for finish in mid 2017, at an expected venture of $700m.
The extension task will empower the force station to serve around 100,000 families and create 500 neighborhood employments amid the crest development stage. The development will meet the future force requests in the zone and empower Tampa Electric to supplant the current force buy understandings, which are because of terminate.
Polk power station subtle elements
The force station, covering a region of around 4,300 sections of land, is situated on State Road 37 in Polk County, roughly 13 miles (21km)south-west of the city of Bartow, Florida.
The plant has five units, which incorporate a 260MW Unit I that began business operation in late-1996, two 180MW units (II and III) that came online in July 2000 and May 2002 individually, and two 160MW units (IV and V) that came online in April 2007.
Unit I is an incorporated coal gasification joined cycle (IGCC) office, the first of its kind in the nation, while alternate units are basic cycle burning turbine units. The units at present serve around 75,000 homes altogether.
Extension of the Polk power station
The Polk power station task will fundamentally include the establishment of four warmth recuperation steam generators (HRSGs) furnished with normal gas-let go channel burners, a steam turbine generator (STG), a six-cell mechanical draft cooling tower and a crisis diesel motor generator. The new offices will supplement the current offices.
The HRSGs will recoup waste warmth from the current burning turbine generators (CTGs) to create steam, which will be passed on to the new Alstom STF60C steam turbine and Gigatop generator to deliver the extra electrical force.
The force station improvement likewise includes the development of 40 miles (around 64km) of new transmission lines and overhaul of the current transmission offices to pass on the extra yield to the lattice. The assistant cooling frameworks of the current Unit 1 will likewise be moved up to utilize the new cooling tower set up of the current cooling supply.
The changed over units will utilize characteristic gas as essential fuel and ultra-low-sulfur diesel (ULSD) as move down fuel. The undertaking will likewise present the particular reactant lessening (SCR) innovation at the site, which will diminish nitrogen oxide emanations from the current units by more than 75%. The new offices are relied upon to general expand the proficiency of the current units by 37%.
Late developments at Polk power station
A carbon dioxide catch and sequestration show venture at the site, executed by Tempa Electric in a joint effort with Research Triangle Institute International, was authorized in April 2014. The undertaking was executed with a DOE Federal award of roughly $168m.
The created Polk plant will exhibit RTI's warm-blend gas (syngas) cleanup innovation amid a one-year show period. It is required to catch 300,000t of CO² from the current IGCC unit and sequester it more than 5,000ft underneath the force station in a saline arrangement.
The recycled water task was finished in April 2015 through the synergistic exertion of Tampa Electric, Southwest Florida Water Management District and the city of Lakeland.
The $120m venture included the development of a recycled water pumping station and a 15 miles (around 24km) pipeline between the city of Lakeland's wetland treatment framework and the force station, an opposite osmosis water-treatment framework at the force plant's site and two profound infusion wells, found more than 1.5 miles underground on the force plant site.
The office recovers waste-water from the city of Lakeland and serves as cooling water at the Polk power station, subsequent to being dealt with. Extra periods of the venture to recover the wastewater from the urban communities of Polk County and Mulberry are relied upon to come online by 2017.
Temporary workers included with Polk Power Station development
The HRSGs for the venture were produced in South Korea. The gatherings included in the transportation of the HRSGs to the venture site incorporate Babcock Power, Port Manatee, BBC Chartering, Federal Marine Terminals and Beyel Brothers Crane and Rigging.The development contractual worker for the extension undertaking is Robins and Morton, while the building accomplice to the engineer is Black and Veatch.
