  • Coal-fired Power Station | GDF SUEZ
    anthracite The last three coals in this process are usually called black coal the coal mined for power generation at Hazelwood and Loy Yang B is brown coal in which the process of coalification began 45 million years ago The main difference between brown and black coal is brown coal has a much higher moisture content The brown coal at Hazelwood and Loy Yang B has between 60 and 70 moisture whereas black coal has between 8 and 12 THE ELECTRICITY GENERATING PROCESS Hazelwood Power Station The Hazelwood mine covers an area of over 800 hectares The coal is mined by bucket wheel dredgers and is transported to the power station by a 40 kilometre conveyor system and into a pulverising mill To reduce the high water content it is crushed and dried into a very fine powder which allows it to burn more easily The intense heat from burning the coal turns water in the boilers into super heated steam The water in the boiler is contained within thousands of pipes When the coal is burnt a lot of ash is produced This ash by product is processed by electro static precipitators which capture 95 99 per cent of the dust before allowing the hot gases to escape into the atmosphere via giant chimneys The high pressure steam from the boiler is injected onto the blades in the steam turbine causing the blades to rotate at 3000 revolutions per minute The turbine turns a generator which contains an electromagnet at very high speed about 50 times a second inside copper wire conductors This generates electricity As the steam leaves the turbine it is converted back into water in the condenser The pipes inside the condenser are full of cool water The majority of power stations use river water and

    its electricity output thereby increasing the energy efficiency of the station efficiency refers to how well the power station transforms energy from gas to electricity The process of generating electricity at Pelican Point Power Station works like this Natural gas arrives at the Power Station via a pipeline The gas is burnt in a mixture of compressed air The air is drawn through filters and then compressed This process produces high pressure high temperature combustion gases that drive a turbine connected to a generator The generator spins an electromagnet at very high speed about 50 times a second inside copper wire conductors This generates electricity The exhaust gases from the turbines are then directed to the Heat Recovery Steam Generator where it is used to boil water in a series of pipes producing superheated steam Any remaining exhaust gas is released through a large chimney The superheated steam is delivered to a steam turbine which in turn drives another generator to produce electricity The steam powered turbine and generator increases the overall efficiency of the gas steam turbine or combined cycle operation of the power station to more than 53 per cent The steam used to rotate the steam turbine

  • Mining Coal | GDF SUEZ
    cut mine covers a very large area over 1000 hectares at grass level The perimeter of the mine is over 16 kilometres The mine is larger than the size and depth of Uluru Ayers Rock though it would be a better fit if you turned the great rock upside down The brown coal is covered by overburden mainly a combination of clay gravel and top soil This must be removed before the coal can be mined although the top soil is reclaimed for mine rehabilitation work The average depth of overburden is 18 metres and the average depth of the coal seam is around 100 metres The key to mining brown coal at Hazelwood is the bucket wheel excavator or dredger the huge digging machine that eats into the batters walls of the soft coal The dredger digs and then deposits the coal on the first of many conveyor systems which eventually transport this coal to the power station boilers The dredger is an enormous and powerful machine but it is easy to overlook the fact that it is also a precision instrument The dredgers operations are guided by lasers In fact this was one of the world s first applications of laser technology in the industry Lasers provide reference for the path of the bucketwheel and ensure that digging is efficient and minimises waste GDF SUEZ Australian Energy has four dredgers and multiple conveyors systems on different levels in the Hazelwood mine Three are generally scheduled to dig coal with two supplying coal to the power station and one removing the overburden material The fourth dredger is available in case of plant breakdown HAZELWOOD MINE CONVEYORS Each dredger supplies coal to a system of conveyor belts which carry the coal out of the mine Over 21 kilometres of conveyors
