The Hekinan Power Plant ( Japanese 碧南 火力 発 電 所 , Hekinan karyoku hatsudensho ) is a coal-fired power plant in Japan , which is located on Mikawa Bay near the city of Hekinan in Aichi Prefecture . With an installed capacity of 4.1  GW , it is the most powerful coal-fired power plant in Japan. After the Kawagoe power plant (4,802 MW), it is the Chubu Electric Power Company's most powerful power plant that uses fossil fuels. It serves to cover the base load .

On August 22, 2003, the Hekinan power plant reached a total of 200 billion kWh produced since the first unit went into operation on October 18, 1991. On January 18, 2007 the mark of 300 billion kWh generated was exceeded. It thus produces around 30 billion kWh per year, which is not quite a quarter of the total electricity generated by Chubu Electric Power.

Power plant units

The power plant consists of a total of five blocks with different capacities that went into operation from 1991 to 2002. The following table gives an overview:

block Max. Power (MW) Start of operation turbine generator Steam boiler
1 700 10/18/1991 Toshiba Toshiba MHI
2 700 06/12/1992 Babcock- Hitachi Hitachi Hitachi
3 700 04/22/1993 MHI Melco IHI
4th 1000 11.2001 Toshiba Toshiba IHI
5 1000 11.2002 Toshiba Toshiba IHI

All blocks use supercritical steam generators ( English supercritical : see supercritical water ). In blocks 1 to 3, the temperature of the steam is 538 and 566 ° C and the pressure is 24.1  MPa . For blocks 4 and 5, the corresponding values ​​are 566 and 593 ° C and 24.1 MPa. The speed of machines 4 and 5 is 3,600 revolutions per minute.

On January 20, 2014, a fire broke out in Block 3.

fuel

The Hekinan power plant requires around 10 million tons of coal per year; the price on August 31, 2012 was around US $ 90 per ton. From October 1990 to November 11, 2006, a total of 100 million tonnes of coal were delivered to the power plant. In the 2005 financial year, most of the coal came from Australia (56.6%), Indonesia (32.7%) and China (7.8%). The coal is delivered by ship. The power plant therefore has its own pier .

In 2007, Chubu announced that around 400,000 tons of wood waste from paper production will be burned together with the pulverized coal. In 2010, Chubu announced that tests had been carried out since May 2009 and that around 300,000 t of woody biomass would be burned in the future. This corresponds to approx. 3% of the coal consumption.

In the 2005 financial year, approx. 930,000 t of ash were produced, which were used as follows:

  • Aggregate for cement 760,000 t
  • other use 100,000 t, e.g. B. as artificial zeolites 3,000 t or as an addition to plastic and rubber
  • Disposal on landfill 70,000 t.

Others

The English newspaper The Telegraph ranked Hekinan in 2007 with 28.9 million t in 8th place of the 25 largest CO 2 emitters worldwide. According to the Kiko Network, Hekinan was the largest CO 2 emitter in Japan with 24.1 million t . According to this source, Hekinan ranks 65th among the most powerful power plants in the world.
