Butibori Power Plant

Last updated

Butibori Power Project is a coal-based thermal power plant located at Butibori near Nagpur in the Indian state of Maharashtra. The power plant is operated by the Reliance Power.

Contents

The Engineering, procurement and construction contract is given to Reliance Infrastructure and Shanghai Electric Corporation of People's Republic of China is supplying the boiler, turbine and generator (BTG) for the power plant. [1] Along with Power generation units, there are two reservoirs of water, one of which has intake from the MIDC area and the other from the nearby Wadgaon dam. The premises of the power plant also include a Coal Handling Plant (CHP), an Ash Handling Plant (AHP) and a Water Treatment Plant.

The basis for generation of electricity in this plant is the reheat Rankine cycle.

Working Process

The plant has two 72 m high tangentially fired, water tube boilers. The boilers have a capacity of 1024 m3/hr each, with the output steam being supplied at 167 bar and 540 °C. The boilers are heated by coal. The coal is initially about 300 mm in size. It is crushed to 20 mm and then put into a coal mill, which pulverizes it into extremely fine powder of around 70 microns. The powdered coal is then supplied to the top of the boilers via tubes and primary air (PA) fans, where it is burnt to generate heat and convert the water in the boilers to steam.

The steam generated in the boilers is then supplied to the turbine, which is coupled to a generator. The steam is supplied via 2 out of 3 boiler feed pumps. Two pumps are always active, while one pump is on standby. The turbines run at a constant speed of 3000 rpm, so as to provide a steady output of 50 Hz. The turbines are divided into 3 parts : High Pressure (HP) turbine, Intermediate Pressure (IP) turbine and a Low Pressure (LP) turbine. The steam is supplied to the HP, which sends it back for reheating. This reheated steam then goes to the IP and the LP, which in turn run the generator to produce electricity.

The steam let out from the turbine goes to a condenser, which converts the steam into water to be reused in the boiler.

The burning of coal releases ash and flue gases. The flue gases are released out into the surroundings, 220 m above the ground level via two chimneys. Post combustion, the mixture of flue gases and ash passes over an Electrostatic Precipitator (ESP). This attracts the ash particles, which are usually positively or negatively charged, to its surface and lets the uncharged flue gases through to the chimneys. This ESP has 8 stages, to even out the accumulation of ash and prevent overloading. The ash is collected in a storage via a hopper. This ash is then carried away to the AHP until it is shipped if the need arises.

Before the water is supplied into the boilers, it is treated in the water treatment plant, which removes all dissolved minerals in the water, disinfects it and removes dissolved air and silica. The turbidity of water is also reduced to less than 1 NTU. Chemicals used in the Water treatment plant are Lime Dolomite, Poly electrolyte, Chlorine gas, SMBS (Sodium metabisulphate) and an antiscalant.

Capacity

It has an installed capacity of 600 MW.

Although the plant has a capacity of 660 MW, it supplies only about 540 MW to the grid. 30% of the power generated is used to run the plant itself.

Status updates

Vidarbha Industries Power Limited (VIPL), a subsidiary of Reliance Power Limited, has made 141 out of its 170 staffers at the 600 MW Butibori power plant tender their resignation. The plant was closed since January 2019 and the staffers were doing only maintenance and preservation work. The remaining 29 staffers will continue this work. Station director Rajendra Kale said the plant had closed down due to regulatory issues after Adani Power took over Reliance’s power distribution business in Mumbai. “We initially closed one 300 MW unit and then had to close the second one too,” he added.

A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy. On land, when used to make electricity the most common type is called a combined cycle gas turbine (CCGT) plant. The same principle is also used for marine propulsion, where it is called a combined gas and steam (COGAS) plant. Combining two or more thermodynamic cycles improves overall efficiency, which reduces fuel costs.

A thermal power station is a type of power station in which heat energy is converted to electrical energy. In a steam-generating cycle heat is used to boil water in a large pressure vessel to produce high-pressure steam, which drives a steam turbine connected to an electrical generator. The low-pressure exhaust from the turbine enters a steam condenser where it is cooled to produce hot condensate which is recycled to the heating process to generate more high pressure steam. This is known as a Rankine cycle.

Cockenzie power station was a coal-fired power station in East Lothian, Scotland. It was situated on the south shore of the Firth of Forth, near the town of Cockenzie and Port Seton, 8 mi (13 km) east of the Scottish capital of Edinburgh. The station dominated the local coastline with its distinctive twin chimneys from 1967 until the chimneys' demolition in September 2015. Initially operated by the nationalised South of Scotland Electricity Board, it was operated by Scottish Power following the privatisation of the industry in 1991. In 2005 a WWF report named Cockenzie as the UK's least carbon-efficient power station, in terms of carbon dioxide released per unit of energy generated.

Kingsnorth power station was a dual-fired coal and oil power station on the Hoo Peninsula at Medway in Kent, South East England. The four-unit station was operated by energy firm E.ON UK, and had a generating capacity of 2,000 megawatts. It was capable of operating on either coal or oil, though in practice oil was used only as a secondary fuel or for startup. It was also capable of co-firing biofuel, up to a maximum of 10% of the station's fuel mix. A replacement power station, also coal-fired, was considered by owners E.ON, but plans were abandoned. The proposed replacement attracted substantial public protests and criticism, including the 2008 Camp for Climate Action.

Dunston Power Station refers to a pair of adjacent coal-fired power stations in the North East of England, now demolished. They were built on the south bank of the River Tyne, in the western outskirts of Dunston in Gateshead. The two stations were built on a site which is now occupied by the MetroCentre. The first power station built on the site was known as Dunston A Power Station, and the second, which gradually replaced it between 1933 and 1950, was known as Dunston B Power Station. The A Station was, in its time, one of the largest in the country, and as well as burning coal had early open cycle gas turbine units. The B Station was the first of a new power station design, and stood as a landmark on the Tyne for over 50 years. From the A Station's opening in 1910 until the B Station's demolition in 1986, they collectively operated from the early days of electricity generation in the United Kingdom, through the industry's nationalisation, and until a decade before its privatisation.
