Coalfired power station Wikipedia

Coalfired power station Wikipedia

A coalfired power station is a type of fossil fuel power station. The coal is usually pulverized and then burned in a pulverized coalfired boiler. The furnace heat converts boiler water to steam, which is then used to spin turbines that turn generators.

A 1000 MW dry cooled coalfired power station would typically require around GL of water per year. While dry cooling reduces water consumption to around 2 GL/year (from around 17 GL/year), it also reduces sentout efficiency, which leads to higher fuel requirements and higher emissions of carbon dioxide and other greenhouse gases. ...

In the western US, wetrecirculating systems are predominant. Drycooling systems use air instead of water to cool the steam exiting a turbine. Drycooled systems use no water and can decrease total power plant water consumption by more than 90 percent. [2] The tradeoffs to these water savings are higher costs and lower efficiencies.

The turbines at coal fired power stations are steam driven. The steam is produced using highly purified water demineralised water. This water needs to be recovered due to the high costs involved in its production and also to save water. When the spent steam leaves the turbine it is at a very low pressure and high volume.
