Suralaya Power Station is a coal-fired power station located on Cilegon, Banten in Indonesia. The station has a maximum generating capacity of 4,025 megawatts. [1]

Coal-fired power station One or more generators which convert coal into electricity

A coal-fired power station or coal power plant is a thermal power station which burns coal to generate electricity. Coal-fired power stations generate over a third of the world's electricity but cause hundreds of thousands of early deaths each year, mainly from air pollution.

Banten Province in Indonesia

Banten is the westernmost province on the island of Java, in Indonesia. Its provincial capital city is Serang. The province borders West Java and the Special Capital Region of Jakarta to the east, the Java Sea to the north, the Indian Ocean to the south, and the Sunda Strait to the west, which separates Java from the neighbouring island of Sumatra. The population of Banten was officially estimated at 12,959,169 in the middle of 2019, up from over 10.6 million during the 2010 census. Formerly part of the province of West Java, Banten became a separate province in 2000. The province is a transit corridor to the neighbouring Indonesian island of Sumatra. Historically, it has had a culture distinct from the rest of Java and that of the broader Indonesian archipelago. In recent years, the northern half, particularly those areas near Jakarta and the Java Sea coast, have experienced rapid rises in population and urbanization, while the southern half, particularly that facing the Indian Ocean, maintains more of its traditional character.

History

The power station project was built in four steps and now has eight units. Step 1 = 2x400 MW operated in 1984 Step 2 = 2x400 MW operated in 1984 Step 3 = 3x600 MW operated in 1997 Step 4 = 1x625 MW operated in 2011

Step 1 with two units was built in 1984. Coal is the primary fuel used in this unit. Units 5,6,7 and 8 were built in 1997 and 2011, this is the newest and most efficient unit at Suralaya Power Station. It is able to burn a wide variety of fuels like natural gas, heavy fuel oil, straw, wood pellets and sugarcane in the same burners. The plant facilities can transfer 900 tons of wood pellets per hour from ship to shore, although some environmentalists question the benefits of biomass. As a by-product, high quality plaster is made when cleaning the flue gas.

Natural gas fossil fuel

Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium. It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years. The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in the gas.

Heavy fuel oil Fuel oils of a tar-like consistency

Heavy Fuel Oil (HFO) is a category of fuel oils of a tar-like consistency identified as a "worse case substance". Also known as bunker fuel or residual fuel oil, HFO is the result or remnant from the distillation and cracking process of crude oil. For this reason, HFO is contaminated with several different compounds including aromatics, sulfur and nitrogen, making emission upon combustion more polluting compared to other fuel oils. HFO is predominantly used as a fuel source for marine vessel propulsion due to its relatively low cost compared to cleaner fuel sources such as distillates. The use and carriage of HFO on-board vessels presents several environmental concerns namely: the risk of oil spill and the emission of toxic compounds and particulates including black carbon. Presently, the use of HFOs is banned as a fuel source for ships travelling in the Antarctic as part of the International Maritime Organization's (IMO) International Code for Ships Operating in Polar Waters. For similar reasons, an HFO ban in Arctic waters is currently underway as IMO committed to the prohibition of the use or carriage of HFO within the next several years.

Straw agricultural byproduct of cereal crops

Straw is an agricultural byproduct consisting of the dry stalks of cereal plants after the grain and chaff have been removed. It makes up about half of the yield of cereal crops such as barley, oats, rice, rye and wheat. It has a number of different uses, including fuel, livestock bedding and fodder, thatching and basket making.

Power lines

The power plant connects to the industrial and metropolitan area using 500 kV and 150 kV transmission lines.

Kingsnorth power station

Kingsnorth 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 2000 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.
