Get Coal Power Plants Webquest Answer Key

Coal impacts: air pollution When coal is burned it releases a number of airborne toxins and pollutants. They include mercury, lead, sulfur dioxide, nitrogen oxides, particulates, and various other heavy metals.

Initially coal is pulverized (D) and burnt in a furnace (C). The heat energy released is used to heat water into super hot steam which is then used to turn turbines (B). The turbines drive the generators (A) which produce electricity. The steam is then condensed and recycled.

Power Plant Start-up Procedures Filling the condensate/feedwater system. Firing a steam boiler. Rolling a steam turbine. Synchronizing a generator to the electrical grid. Increasing load.

There are two main phases in coal formation: peatification and coalification. Bacterial activity is the main process that creates the peat during peatification. Increasing temperature and pressure from burial are the main factors in coalification.

Burning fossil fuels at power plants creates emissions of sulfur dioxide (SO2), nitrogen oxides (NOX), particulate matter (PM), carbon dioxide (CO2), mercury (Hg), and other pollutants.

Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

The Rankine cycle or Rankine Vapor Cycle is the process widely used by power plants such as coal-fired power plants or nuclear reactors. In this mechanism, a fuel is used to produce heat within a boiler, converting water into steam which then expands through a turbine producing useful work.

Coal-fired power plants burn coal to make steam and the steam turns turbines (machines for generating rotary mechanical power) to generate electricity. Many industries and businesses have their own power plants, and some use coal to generate electricity for their own use and mostly in combined heat and power plants.
